Clinical examination for Sciatica

Sensory testing

—Posterior thigh
—Lateral & posterior calf
—Foot


Power testing

—Footdrop (plantar flexed foot)
—Weakness of knee flexion


Reflex testing

—Knee jerk – INTACT
—Ankle jerk – ABSENT
—Plantar response - ABSENT


Nerve root tension tests
- Moving the legs in certain ways that stretch the sciatic nerve
- If the patient experiences pain during these tests, an irritated sciatic nerve is likely to be a source of the pain.


1. Straight Leg Raising test (SLR) & Bragard’s test
- positive if pain occurs between 20 & 70 degrees


2. Crossed straight leg raise test
- Symptoms are reproduced in the symptomatic leg by performing a straight leg raise test on the opposite leg

3. Sciatic palpation test

Complications Arising from sciatica, as well as Prognosis

Complications
• 
Loss of Bowel or Bladder Function.

Urinary continence, a strong, sudden need to urinate, followed by instant bladder contraction and involuntary loss of urine. Urination occurs without knowing.Occurs during rising from bedrest, especially post-recovery after surgery.

Partial or complete loss of leg movement
• 
. Partial damage to the nerve may demonstrate
weakness of knee flexion (bending),
weakness of foot movements,
difficulty bending the foot inward (inversion),
or bending the foot down (plantar flexion). A person's reflexes may be abnormal, with weak or absent ankle-jerk reflex.

Several different tests can be performed to find the cause of sciatic nerve dysfunction.

• 
Partial or complete loss of sensation in the leg
.Abnormal sensations such as tingling or numbness which may be due from remaining in the same seated or standing position for a long time, injury to a nerve (eg: a low back injury can cause numbness or tingling down the back of the leg), pressure on the spinal nerves (eg: herniated disc) or pressure on peripheral nerves from enlarged blood vessels, tumors, scar tissue or infection.

• 
Medication Side effects : Nsaids
1.Gastric Ulceration
2.Bleeding
3.BP increase
4.Delayed Stomach Emptying
5. Depression
6. Confusion
7. Elderly : Tinnitus *ringing in the ears* , headache, dizziness, skin rash allergy*
8. Weight gain
9. Kidney failure


Prognosis
1)Studies shows 75% patients suffer
at least one recurrence of backpain over
a course of year.

2)Most acute low back pain recover within a month or so.
1/3 with uncomplicated low back pain recovers within a week.

Intervertebral disc prolapse

The intervertebral disc bursts and fragments of the outer annulus fibrosus, together with some of the inner gelantinous nucleus pulposus, press on ligaments and nerves running close to the disc and produce pain.Once this has happened, that disc will never be normal again. It's resistance to further injury is considerably reduced and anyone who has had a burst intervertebral disc is always at risk of further episodes of acute pain.
Pathophysiology
Although any disc in the entire spine can prolapse or burst, the most common ones to which this happens are the lowest two, that is between the fourth and fifth lumbar vertebrae and between the fifth lumbar and the top of the sacrum. The most likely explanation is that the stresses experienced by the spine are the greatest at these levels. Also the sacrum does not stand vertically but is tilted backwards, so producing a sharp curve in this region and giving a wedge shape to the discs. This wedge shape may concentrate the stresses in the back of the disc so making these lower lumbar discs particularly liable to damage. Briefly in a prolapse, the disc ruptures or bursts so that debris from the disc protrudes and can damage the surrounding structures. Most commonly these ruptures occur at the back of the disc but to one side or the other. These are known technically as the postero-lateral edges of the disc. Sometimes, however, the burst may occur directly backwards in the midline and this is known as a central posterior prolapse. Prolapsed disc bursting backwards and to one side due to the presence of the posterior longitudinal ligament in the spinal canal.
Stages of Spinal Disc Herniation
Disc herniation can occur in any disc in the spine, but the two most common forms are lumbar disc herniation and cervical disc herniation. The former is the most common, causing lower back pain (lumbago) and often leg pain as well, in which case it is commonly referred to as sciatica.
Lumbar disc herniation occurs 15 times more often than cervical (neck) disc herniation, and it is one of the most common causes of lower back pain. The cervical discs are affected 8% of the time and the upper-to-mid-back (thoracic) discs only 1 - 2% of the time.
The following locations have no discs and are therefore exempt from the risk of disc herniation: the upper two cervical intervertebral spaces, the sacrum, and the coccyx.
Cervical disc herniation
Cervical disc herniations occur in the neck, most often between the fith & sixth (C5/6) and the sixth and seventh (C6/7) cervical vertebral bodies. Symptoms can affect the back of the skull, the neck, shoulder girdle, scapula,shoulder, arm, and hand. The nerves of the cervical plexus and brachial plexus can be affected.
Thoracic disc herniation
Thoracic discs are very stable and herniations in this region are quite rare. Herniation of the uppermost thoracic discs can mimic cervical disc herniations, while herniation of the other discs can mimic lumbar herniations.
Lumbar disc herniation
Lumbar disc herniations occur in the lower back, most often between the fourth and fifth lumbar vertebral bodies or between the fifth and the sacrum. Symptoms can affect the lower back, buttocks, thigh, and may radiate into the foot and/or toe. The sciatic nerve is the most commonly affected nerve, causing symptoms of sciatica. The femoral nerve can also be affected.[9] Can cause the patient to experience a numb, tingling feeling throughout one or both legs and even feet or even a burning feeling in the hips and legs.
Risk Factors
-Disc herniations can occur from general wear and tear, such as jobs that require constant sitting, but especially jobs that require lifting.
-Traumatic (quick) injury to lumbar discs commonly occurs from lifting while bent at the waist, rather than lifting while using the legs with a straightened back.
- Minor back pain and chronic back tiredness is an indicator of general wear and tear that makes one susceptible to herniation on the occurrence of a traumatic event from bending to pick up a pencil or a traumatic injury from a fall.
-Smoking is a major risk factor as the chemicals within smoke cause diminished nutrition and oxygenation of the discs leading to dehydration & degeneration which can then proceed to herniation.
-Mutation in genes coding for proteins involved in the regulation of the extracellular matrix, such as MMP2 and THBS2, has been demonstrated to contribute to lumbar disc herniation.

2. Status

- Many migrant workers have difficulty accessing services such as a GP, bank account and state benefits

3. Work permits

- e.g. delays can also occur at the Home Office.

4. Family and dependants

- Money sent

Symptoms of Sciatica

Symptoms of sciatica
-Pain that travels from the low back, through the buttocks, downward into the leg, and sometimes into the foot.
- Burning and tingling sensations( pins-and-needles feeling) in your leg.
- Partial leg numbness or weakness. In some cases, you may have pain in one part of your leg and numbness in another.
- Worsening of symptoms when squatting, coughing, trying to stand up.... coz these maneuvers can increase pressure around the nerve and magnify the symptoms of sciatica.

Seek medical attention if your pain persists — and seek immediate attention if you have any of the following emergency signs:

* Pain is getting worse.
* Pain affects your every day activities.
* Leg weakness or numbness.
* Loss of bowel or bladder control.- Cauda equina syndrome
- rare, but an emergency
- caused by a prolapsed disc.
- cause low back pain plus: problems with
bowel and bladder function (usually unable
to pass urine), numbness in the 'saddle'
area (around the anus), and weakness in one
or both legs.
- preserve the nerves to the bladder
and bowel from becoming permanently damaged

When you're describing your symptoms to your doctor, it's helpful to be as exact as possible.
So when you feel pain, is it
-especially intense above your knee?
-below your knee and into your foot?
-on the side of your foot?
-in your big toe and maybe in your ankle, too?

Alternative Treatments & Management for Sciatica

  • Exercise/Stretching - strengthening the abdominal and back muscles in order to provide more support for the back.
  • Ice - reduce inflammation, used in the first 48 hrs
  • Spinal Manipulation Therapy- relieve pain and improve physical functioning
  • Acupuncture & Acupressure- restore qi flow
  • Yoga
  • Cognitive based therapy- change perception of pain

Treatment, surgery, management.

Surgery for Sciatica


Most patients with sciatica respond well to non-surgical treatments (such as medication), so spine surgery is seldom needed to treat it. However, there are situations when you may want to go ahead with spine surgery:

  • You have bowel or bladder dysfunction. This is rare, but it may occur with spinal cord compression.
  • You have spinal stenosis, and your doctor feels that surgery is the best way to treat it.
  • You are experiencing other neurologic dysfunctions, such as severe leg weakness.
  • Your symptoms become severe and/or non-surgical treatment is no longer effective.

There are many types of surgical procedures used in spine surgery, and your spine surgeon will recommend the best procedure to treat your sciatica. And remember, the final decision to have surgery is always up to you.

Two common spinal surgeries for sciatica are:

  • Discectomy or Microdiscectomy: In both of these procedures, the surgeon removes all or part of a herniated disc that's pushing on your sciatic nerve and causing your sciatica symptoms. The difference between the procedures is that a microdiscectomy is a minimally invasive surgery. The surgeon uses microscopic magnification to work through a very small incision using very small instruments. Because the surgery is minimally invasive, you should recover more quickly from a microdiscectomy.
  • Laminectomy or Laminotomy: These procedures both involve a part of the spine called the lamina—a bony plate that protects the spinal canal and spinal cord. A laminectomy is the removal of the entire lamina; a laminotomy removes only a part of the lamina. These procedures can create more space for the nerves, reducing the likelihood of the nerves being compressed or pinched.
MicroEndoscopic Discectomy (MED)
A patient is brought into the operating room and is put under general anesthesia. Some surgeons have chosen to perform MED under local or spinal anesthesia allowing the patient to stay awake throughout the procedure. The patient is turned onto his abdomen and padded into position. A fluoroscope (floor-o-scope, a machine which projects live x-ray pictures onto a screen) is brought in for use during the remainder of the operation. The patient's back is scrubbed with sterile soap, and a sterile field is cre-ated. Drapes are placed accordingly, and the surgery begins.

The disc space is confirmed using the fluoroscope, and a long acting, local anesthetic is injected through the muscle and around the bone protecting the disc. A half to one-inch incision is made. A thin wire is placed through the incision and lowered until it touches the bone. Progressively larger dilators are brought down on top of one another following the wire. In this manner, the muscle is stretched rather than cut. By the time the 4th or 5th dilator is placed, the muscles are stretched to an opening roughly the size of a nickel. It is through this opening that the procedure is performed. Over the last dilator, a working channel is positioned; this circular retractor holds back the muscles and now the dilators can be removed. The retractor is held in place by a mechanical arm attached to the table.

Finally, the endoscope (en-doe-scope) is attached to the edge of the working channel. The endoscope is a camera about as thick as the ink in a ballpoint pen. It projects an image of the base of the working channel blown up to the size of the TV screen. This allows for microscopic manipulation and removal of the tissues.

When a small amount of muscle is left over the lamina (lamb-in-ah), or exposed bone, this is cleaned off. In order to access the nerve, this roof of bone must be removed; this can be done with a small, high-speed drill or a small bone-biting tool called a Kerrison rongeur. The bone just below the endoscope covers the nerve, as it is about to exit the spine. By removing the bony cover, the nerve can be exposed and then safely moved away. After the bone is removed, the yellow ligament (a rubbery layer of tissue) can be seen which protects the underlying nerves. All the nerves, except the exiting nerve, are grouped together in the thecal sac where they float loosely in spinal fluid.

Care is taken as the yellow ligament is separated and removed, exposing the thecal sac and the exiting nerve root. A very small retractor is placed just on the outside of the root, and the nerve and thecal sac are moved together. Directly below the retractor lies the ruptured disc.

Ruptured disc material has a consistency similar to uncooked shrimp. When a small puncture is made into the tissue covering the disc, the disc will often times begin to ooze out. Various tools are used to remove the ruptured disc and other loose fragments of disc in the surrounding area. No attempt is made to remove the entire disc at that level - that is what is supporting those vertebrae. When completed, the small hole will fill in on its own. The case at this point is essentially finished.

The wound is irrigated with antibiotics. As the scope is withdrawn, your surgeon can see the tissues coming back together. A stitch or two is placed at various levels to hold the tissues together to help healing. Typically, buried stitches are used to close the skin, and none need to be removed at a later date. Commonly, Steri-Strips® (small sterile tape) and a loose bandage are applied to the wound. The patient is then positioned on a stretcher, woken up, and sent to the recovery room. In a few hours, if all goes well, he or she may leave the hospital.

Laminectomy

The goal of a laminectomy is to relieve pressure on the spinal cord or spinal nerve by widening the spinal canal. This is done by removing or trimming the lamina (roof) of the vertebrae to create more space for the nerves. A surgeon may perform a laminectomy with or without fusing vertebrae or removing part of a disc. Various devices (like screws or rods) may be used to enhance the ability to obtain a solid fusion and support unstable areas of the spine.

The patient is usually positioned face down on an operating frame. A small incision (usually about 3-4 inches, though it may be longer depending on how many levels of the spine are affected) is made in the lower back.

The surgeon uses a retractor to spread apart the muscles and fatty tissue of the spine and exposes the lamina. A portion of the lamina is removed to uncover the ligamentum flavum - an elastic ligament that helps connect two vertebrae.

Next an opening is cut in the ligamentum flavum in order to reach the spinal canal. Once the compressed nerve can be seen, the cause of compression can be identified. Most cases of spinal compression are caused by a herniated disc. However, other sources of pressure that can cause compression may include:

1 - A disc fragment (this will often cause more severe symptoms)

2 - An osteophyte or bone spur (a rough protrusion of bone)

3 - Protruding/degenerating discs

4 - Facet arthritis and/or cysts

5 - Tumors

The surgeon retracts the compressed nerve and the source of the compression is removed and pressure on the spinal nerve or nerve components is relieved.

If necessary, the surgeon will perform a spinal fusion with instrumentation to help stabilize the spine. This occurs when a lot of bone needs to be removed and/or when multiple levels are operated on. A spinal fusion involves grafting a small piece of bone (usually taken from the patient's own pelvis) onto the spine and using spinal hardware, such as screws and rods, to support the spine and provide stability.

Then the procedure is finished! The surgeon will close the incision either using absorbable sutures (stitches), which absorb on their own and do not need to be removed, or skin sutures, which will have to be removed by the surgeon after the incision has healed.


Pictures and a simple explanation will be delivered on Friday.

Causes and predisposing factors for osteoarthritis

What causes osteoarthritis?

-due to excessive strain over prolonged periods of time,
-or due to other joint diseases, injury or deformity.

Primary osteoarthritis is commonly associated with ageing and general degeneration of joints.

Secondary osteoarthritis is generally the consequence of another disease or condition, such as repeated trauma or surgery to the affected joint, or abnormal joint structures from birth.
Some people may have developmental or congenital abnormalities of the joints that may cause early degeneration and subsequently cause arthritis

Predisposing factors
Unalterable
• Age
• Gender
• Race
• Genetics

Potentially Preventable
• Obesity
• Injury and joint trauma- in the knee from fractures and torn ligaments
and cartilage (menisci)
• Mechanical stress
• Deformity and malalignment in the hip, growth abnormalities or childhood
hip problems
• Vitamin deficiency
• Other diseases that affect the bones and joints.

Signs and Symptoms of Osteoarthritis

  • Joint soreness after inactivity or periods of overuse of a joint.
  • Stiffness after rest and disappears quickly as activity begins again.
  • Morning stiffness lasting no longer than 30 minutes.
  • Joint pain which is less in the morning and stronger at the end of the day following activity.
  • Muscle atrophy around joints caused by inactivity can increase pain.
  • Pain and stiffness can affect posture, coordination and ability to walk.
  • Joints of the knees, hips, fingers, lower spine, and neck are most commonly affected by osteoarthritis. The knuckles, wrists, elbows, shoulders and ankles are rarely affected by osteoarthritis except when you injure or overuse the joint.
  • Signs of hip osteoarthritis may include pain in the groin, inner thigh, or buttocks and a pronounced limp.
  • Signs of knee osteoarthritis may include pain exacerbated by moving the knee, knee locking or catching, pain when standing up from a chair, pain when going up and down stairs, and weakening thigh muscles.
  • Signs of osteoarthritis of finger may include pain and swelling of the finger joints, the presence of Heberden's nodes or Bouchard's nodes, enlarged joints, and problems with manual dexterity.
  • Signs of osteoarthritis of the feet may first be revealed by pain and tenderness in the large joint of the big toe. Certain shoes, such as high heels, can provoke pain in osteoarthritic feet too.
  • Osteoarthritis of the spine occurs when there is deterioration of spinal discs. The breakdown can cause osteophytes (bone spurs) to develop. The neck and lower back are stiff and painful. Pressure on nerves in the spinal cord can cause pain radiating to the neck, shoulder, arm, lower back, and legs or numbness in arms and legs.
  • Risk factors for osteoarthritis include: overweight, age (usually affecting middle age to older people), injury and genetic predisposition to osteoarthritis.

Surgery Part 3, Be the Surgeon

Surgery Part 2 , Alternatives of Hip Surgery



Alternatives of Surgical Treatment
  1. Hip fusion (arthrodesis) was frequently performed before the era of hip replacement. The hip ball is fused to the pelvis. This is a single-operation, permanent-cure for the painful hip. Lost hip motion is made up by extra movement of the knees and spine. You must have a normal spine, normal knees, and a normal opposite hip for arthrodesis to be even considered. Few people today will accept the inconvenience of a stiff hip joint. It is usually only offered to very young people whose work involves heavy manual labor.

  1. An osteotomy of the thigh bone may be an alternative for very young patients. The femur is cut and re-aligned to change the direction of forces across the arthritic hip. It takes three months for the cut bone to heal and the results are unpredictable and almost never permanent. The procedure is much more popular in Europe than in America.



  1. Femoral Hemiarthroplasty (“half a hip replacement”) is sometimes offered to younger patients, when the hip ball is damaged, but the socket cartilage is normal, such as in patients who have osteonecrosis (see Introduction to Hip Disease). The socket is not replaced. The femur component is similar to that of a total hip replacement, but it has a large ball, sized to fill the socket. The metal ball moves directly against the socket cartilage, which can wear out and become painful, requiring a second operation to install an artificial socket. In general, Dr. Huddleston does not recommend hemi-arthroplasty for hip disorders, other than for hip fractures in the elderly. These are usually displaced fractures of the neck of the femur (see figure below). The implant is almost always cemented for hip fractures, except in patients under 65 or so, depending again on bone quality.

Surgery and Surgery Complications

Interactive Surgery
http://www.edheads.org/activities/knee/

Complications of Post-Surgery
  1. Bloodclots in the veins of the legs are the most common complication of hip replacement surgery. As long as the clots remain in the legs they are a relatively minor problem. Occasionally they dislodge and travel through the heart to the lungs (pulmonary embolism). Potentially serious, death due to embolism (BUT RARE). Medication Drug :Coumadin (a blood thinning drug) to help prevent clots from forming after your surgery. Additionally, compressive calf pumps are used and leg exercises are encouraged to prevent blood clots. Blood clots can occur despite all these precautions.

  2. Infection. Risk of infection after joint replacement was much greater than with most other operations, unless special precautions are taken. Bacteria can enter the open wound at the time of the surgery in a regular operating room. Antibiotics given to you before, during and after the operation further help to lower the rate of infection. Chances of infection is 0.5%.The risk of infection in the weeks after the operation is increased if you have rheumatoid arthritis or diabetes, if you have been taking cortisone for prolonged periods of time.
  3. Loosening of the prosthesis from the bone is the most important long-term problem. How durable the prosthesis depends on.....
    1. How well the surgery is done. This is by far the most important factor.
    2. The quality of your bones. The harder your bones are, the better the bond will be, and the longer the replacement will last.
    3. How active you are.
    4. Your weight. You should also keep your weight down
    5. The design of the implant. Small abrasion particles from the implant may play a role in implant loosening. Plastic surfaces shed more particles than metal or ceramic ones.
  4. Dislocation of the hip replacement occurs in a small percentage of patients regardless of how good your surgeon is (some surgeons report as high as 4%).In the first six weeks after the surgery, the ball is only held in the socket by muscle tension. During this time, before scar tissue forms around the ball, and before muscle strength returns, the hip is more likely to dislocate.
  5. Fracture of the femur can occur during hip replacement.
  6. Residual pain and stiffness can occur. In virtually all cases hip replacement will make a significant improvement in your pain and mobility. In most cases, you will have no pain at all, and the hip will feel “normal.” The completeness of the pain relief, and the degree of mobility is partially determined by your hip problem before surgery
  7. The length of the leg may be changed by the surgery. Getting leg lengths exactly right can be very difficult. Some leg length difference may be unavoidable. Sometimes the leg will be deliberately lengthened in order to stabilize the hip or to improve muscle function.
  8. Injury to the arteries or nerves of the leg
  9. Allergy to the metal parts About 15% of the population has skin sensitivity to some metals. All metal implants release some metal ions into the body.

Definition of Osteoarthritis & Joints affected

Definition: Osteoarthritis is the chronic breakdown of cartilage in the joints; the most common form of arthritis occurring usually after middle age

Joints Affected:

  • Weight-bearing joints are the joints which are most commonly affected by osteoarthritis.
  • Weight-bearing joints, such as knees, hips, and the spine are most commonly affected, though osteoarthritis can also affect fingers or any joint with prior traumatic injury, infection, or inflammation.
  • Bony nodes and knobs on fingers(e.g. Heberden's or Bouchard's nodes are a sign of damage from osteoarthritis.
  • Most osteoarthritis patients have increased joint pain during activity, which is relieved with rest

EXERCISE

Although arthritis is a chronic condition, patients can still lead active lives with a manageable amount of pain, fatigue and disability -- if they follow a daily exercise routine.

Exercise reduces joint pain and stiffness, and increases flexibility, muscle strength, and endurance. It also helps with weight reduction and enhances a sense of well-being.

Studies for instance, have shown that strengthening the quadriceps muscles can reduce knee pain and disability associated with osteoarthritis. One study shows that a relatively small increase in strength (20-25 percent) can lead to a 20-30 percent decrease in the chance of developing knee osteoarthritis.


What Are the Kind of Exercises for Arthritis that a Patient Can Follow?

Range-of-motion: To maintain normal joint movement and relieve stiffness. These make the joints flexible.
Strengthening exercises: To increase the strength of muscles that support the joints affected by arthritis.
Aerobic or endurance exercises: They improve cardiovascular fitness, control weight and improve overall body function.

Weight control is important in arthritis because extra weight puts extra pressure on joints. Aerobics also reduce inflammation in some joints.


How Does One Start an Exercise Program for Osteoarthritis?

A skilled physician, knowledgeable about the medical and rehabilitation needs of people with arthritis or physical therapists, can design effective exercise plans for each patient. Depending upon the severity of the condition, the doctor will either recommend his own exercises or refer you to a physical therapist. The latter will know about pain-relief methods, proper body mechanics (placement of the body for a given task, such as lifting a heavy box), joint protection, and energy conservation. For starters, one should stick to easy, range-of-motion exercises or low-impact aerobics.


How Often Should You Exercise?

Range-of-motion: Either daily or every alternate day.
Strengthening exercises: Every alternate day.
Endurance exercises: For 20 to 30 minutes three times a week.


When To Exercise

In general, it is best to exercise:
- At a specific time and place
- When you have the least pain and stiffness
- When you are not tired
- When your arthritis medication is having the most effect


Are There Different Exercises for People With Different Types of Arthritis?

Experienced doctors, physical therapists, and occupational therapists can recommend exercises that are helpful for specific types of arthritis or specific joins.


How Much Exercise Is Too Much?

Experts suggest that you must stop as soon as it begins to pain. Reduce your arthritis exercise program whenever you notice any of the following signs:
- Unusual or persistent fatigue
- Increased weakness
- Decreased range of motion
- Increased joint swelling
- Continuous pain (pain that lasts more than one hour after exercising)

Stop right away if:
- You have chest tightness or pain, or severe shortness of breath
- If you feel dizzy, faint, or sick to your stomachAdditional Tips
- Apply heat to sore joints (optional; many people with arthritis start their exercise program this way).
- Start strengthening exercises slowly with small weights (a 1 or 2 pound weight can make a big difference).


Progress slowly. Exercise at a comfortable, steady pace and give your muscles time to relax between each repetition.

Use cold packs after exercising (optional; many people with arthritis complete their exercise routine this way).

Consider appropriate recreational exercise. Fewer injuries to arthritic joints occur during recreational exercise if it is preceded by range-of-motion, strengthening, and aerobic exercise that gets your body in the best condition possible.

Ease off if joints become painful, inflamed, or red and work with your doctor to find the cause and eliminate it.

Breathe while you exercise. Don't hold your breath. Counting out loud during the exercise will help you breathe deeply and regularly.

Heat relaxes your joints and muscles and helps relieve pain. Mild heat gives the best results. Apply it for no more than 20 minutes at a time.

Lastly, choose an exercises for your arthritis that you enjoy most and make them a habit.

CAM

Glucosamine Chondroitin Therapy (GCT)

Glucosamine hydrochloride and chondroitin sulfate are natural substances that are part of the building blocks found in and around cartilage. Extracts of these substances have been used in Europe for more than a decade to reduce pain and improve mobility in patients with osteoarthritis. For many years, researchers in the U.S. have been studying whether these dietary supplements really work for relieving osteoarthritis pain.

Earlier studies indicated a potential benefit from these agents. However, several high-quality studies involving large numbers of patients have indicated that, in general, glucosamine and chondroitin do not seem to provide any more help than a placebo for the symptoms of osteoarthritis.

Dosage. There are no current recommended dosages. Patients in the National Institute of Health's GAIT trial took 1,500 mg of glucosamine and 1,200 mg of chondroitin.

Side Effects. The safety records of both substances appear excellent. Long-term effects are still unknown, but studies of up to 3 years have reported no significant side effects. However, there are some concerns that glucosamine may affect insulin and blood sugar (glucose) metabolism. Patients with diabetes should not take glucosamine without first talking to their doctors.


Acupuncture

Acupuncture is being increasingly used to reduce osteoarthritis pain. The technique is painless and involves the insertion of small fine needles at select points in the body. The studies of thousands of patients with chronic osteoarthritis pain compared acupuncture to conventional treatment (such as physical therapy and anti-inflammatory drugs). These studies showed positive results lasting for up to 6 months after treatment. However, when acupuncture treatment was compared to sham acupuncture, any benefit was minimal. In any case, acupuncture appears to be a safe and beneficial addition to standard therapy for certain patients, such as pregnant women, who cannot take most pain medications.

Transcutaneous Electric Nerve Stimulation

Transcutaneous electric nerve stimulation (TENS) uses low-level electrical pulses to suppress pain. Patients are barely aware of the sensation. According to one study, the optimal treatment length is 40 minutes. A variant (sometimes called percutaneous electrical nerve stimulation, or PENS) applies these pulses through a small needle to acupuncture points. A review of trials reported that both methods were better than placebo (sham treatments) in treating osteoarthritis of the knee, although additional well-designed studies are needed.


Low-Level Laser Therapy

Low-level laser therapy (LLLT) generates extremely pure light in a single wavelength. It does not produce heat and is painless. Some researchers are combining LLLT with transcutaneous electric nerve stimulation (TENS). Studies report widely varying results, with some showing significant reductions in pain and others reporting no effect. The differences may be due to different approaches, and standardized methods are needed before any benefits can be shown.


Hydrotherapy

Hydrotherapy, also called spa therapy or balneotherapy, is an ancient therapy that uses bathing in mineral baths for soothing pain. Although many studies report positive results, including improved quality of life, very few of them have been rigorously conducted. A major analysis reported weak evidence on any real effect of hydrotherapy on pain or quality of life, but some patients may find comfort in this pleasant therapy.

Magnets

Some people believe placing magnets near your affected joint can relieve osteoarthritis pain. Some small studies have found magnets can provide temporary pain relief, though others haven't found any benefit from magnets. It isn't clear how magnet therapy might work. Still, a variety of magnetic products, such as bracelets, are available. Magnets appear to be safe.

Tai chi and yoga.

These movement therapies involve gentle exercises and stretches combined with deep breathing. Many people use these therapies to abate stress in their lives, though small studies have found that tai chi and yoga may reduce osteoarthritis pain. More study is needed to understand whether tai chi and yoga can relieve osteoarthritis pain. Talk to your doctor if you'd like to give tai chi or yoga a try. When led by a knowledgeable instructor, these therapies are safe. But don't do any moves that cause pain in your joints.

Diet Therapy

1. Remove all inflammatory causes from your diet. Dairy products, wheat, and nightshade plants, including potatoes, peppers, eggplant, tomatoes, and tobacco, are most often responsible for these food allergies. Eliminate all the suspect foods from your diet for at least one month. If this is helping with your arthritis, gradually reintroduce them (one new food every three to four days). This way you can determine which specific food is contributing to your arthritis.

2. Remove or decrease consumption of all animal products other than fish. If possible eat a raw food vegetarian diet (vegetarian plus elimination of all animal products, especially dairy).

3. Periodic supervised fasting is also very effective for osteoarthritis. For more than 50 years, fasting clinics throughout Europe have successfully employed periodic juice fasting for managing arthritis. Fasting enhances the eliminative and cleansing capacity of the lungs, skin, liver, and kidneys. It also rests and restores the digestive system and helps to relax the nervous system and mind.

4. Besides green vegetables, your diet should include: carrots, avocado, sea weeds, spirulina, barley and wheat grass products, sprouts, pecans, soy products, whole grains (such as brown rice, millet, oats, wheat, and barley), seeds (sesame, flax, and pumpkin), and cold-water fish (such as salmon, sardines, herring, and tuna).

5. Avoid the following foods: alcohol, coffee, sugar, saturated fat, hydrogenated fat (margarine), excess salt, spinach, cranberries, plums, buckwheat, nuts.

6. Weight reduction, through diet and exercise, is also recommended in treating arthritis.

Herbal Remedies

Boswellia - anti-inflammatory action, much like NSAIDs but Unlike NSAIDs, however, long-term use of boswellia does not lead to irritation or ulceration of the stomach.

Cayenne (Capsaicin) Capsaicin, the "burning" substance in cayenne creams has been used topically to relieve pain from osteoarthritis. The benefit from cayenne creams, generally containing 0.025-0.075% of the active ingredient capsaicin, has been confirmed in double blind research.

Devils claw (Harpagphytum procumbens)-an analgesic and anti-inflammatory

Ginger (Zingiberaceae). No good evidence indicates that Ginger provides a benefit for osteoarthritis. Limited studies have been conducted with ginger in people with osteoarthritis, and results have been mixed. Side effects of ginger supplements can include heartburn and diarrhea. Talk to your doctor before taking ginger supplements, since they can interfere with prescription medications such as warfarin (Coumadin).

Horsetail: The silicon content of horsetail is believed to exert a connective tissue strengthening and anti-arthritic action in traditional medicine.

Licorice root (Glycyrrhiza glabra)-an anti-inflammatory. Long-term use can elevate blood pressure and increase potassium loss.

Turmeric (Curcumin (Curcuma longa))- an effective anti-inflammatory

White willow has anti-inflammatory and pain-relieving effects. Although the analgesic actions of willow are typically slow-acting, they tend to last longer than aspirin.

Yucca-has long been used to reduce arthritic pain.

Cherries, hawthorn berries and blueberries: Cherries, hawthorn berries, blueberries and other dark red-blue berries are rich sources of anthocyanidins and proanthocyanidins. These compounds are flavonoid molecules that give them their deep red-blue color. These compounds are remarkable in their ability to enhance collagen matrix integrity and structure.

Celery seed extract-acts as an anti-inflammatory

Castor oil hot packs-apply to affected joint

Humour Therapy

Laughing is found to lower blood pressure, reduce stress hormones, increase muscle flexion, and boost immune function by raising levels of infection-fighting T-cells, disease-fighting proteins called Gamma-interferon and B-cells, which produce disease-destroying antibodies. Laughter also triggers the release of endorphins, the body's natural painkillers, and produces a general sense of well-being.

Laughter is infectious. Hospitals around the country are incorporating formal and informal laughter therapy programs into their therapeutic regimens. In countries such as India, laughing clubs -- in which participants gather in the early morning for the sole purpose of laughing -- are becoming as popular as Rotary Clubs in the United States.

Humor is a universal language. It's a contagious emotion and a natural diversion. It brings other people in and breaks down barriers. Best of all it is free and has no known side reactions.

Diagnosis without MRI and X-ray by Matthias

According to the American College of Rheumatology guidelines,
Hip pain plus at least two of the following:

  • ESR of less than 20 mm per hour

  • Femoral or acetabular osteophytes on radiographs

  • Joint space narrowing on radiographs


Laboratory Tests
There is no specific laboratory test to diagnose OA. It is diagnosed by a doctor using a patient’s medical history, a physical exam, X-rays, and in some cases with an examination of synovial fluid from an affected joint. Tests that may be ordered to rule out other conditions and to evaluate the patient’s health include:

These are all the tests. Click on the links to read if you want. But, I'll do up a powerpoint to summarize all these on Friday.

Blood Tests

Blood test results may help identify other causes of arthritis (if present) besides osteoarthritis. Some examples include:

  • Elevated levels of rheumatoid factor (specific antibodies in the synovium) are usually found in patients with rheumatoid arthritis
  • The erythrocyte sedimentation rates (ESR, or "sed rate") indicates inflammatory arthritis or related conditions, such as rheumatoid arthritis or systemic lupus erythematosus.
  • Elevated uric acid levels in the blood may indicate gout.

A number of other blood tests may help identify other rheumatological illnesses.

Tests of the Synovial Fluid

If the diagnosis is uncertain or infection is suspected, a doctor may attempt to withdraw synovial fluid from the joint using a needle. There will not be enough fluid to withdraw if the joint is normal. If the doctor can withdraw fluid, problems are likely, and the fluid will be tested for factors that might confirm or rule out osteoarthritis:

  • Cartilage cells in the fluid are signs of osteoarthritis.
  • A high white blood cell count is a sign of infection, gout, pseudogout, or rheumatoid arthritis.
  • Uric acid crystals in the fluid are an indication of gout.
So, what is ESR ?

Sedimentation Rate
(Erythrocyte Sedimentation Rate or ESR)

What is a sedimentation rate?

A sedimentation rate is common blood test that is used to detect and monitor inflammation in the body. The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the red blood cells (erythrocytes) sedimenting in a tube over a given period of time.

How is a sedimentation rate performed?

A sedimentation rate is performed by measuring the rate at which red blood cells (RBCs) settle in a test tube. The RBCs become sediment in the bottom of the test tube over time, leaving the blood serum visible above. The classic sedimentation rate is simply how far the top of the RBC layer has fallen (in millimeters) in one hour. The sedimentation rate increases with more inflammation.

Normal Results

Adults (Westergren method):

  • Men under 50 years old: less than 15 mm/hr
  • Men over 50 years old: less than 20 mm/hr
  • Women under 50 years old: less than 20 mm/hr
  • Women over 50 years old: less than 30 mm/hr

Children (Westergren method):

  • Newborn: 0 to 2 mm/hr
  • Neonatal to puberty: 3 to 13 mm/hr
This test can be used to monitor inflammatory or cancerous diseases. It is a screening test, which means it cannot be used to diagnose a specific disorder.

However, it is useful in detecting and monitoring tuberculosis, tissue death, certain forms of arthritis, autoimmune disorders, and inflammatory diseases that cause vague symptoms.

Treatment -surgery,physiotherapy management and relieving factor

Surgery :
-Open carpal tunnel release surgery
transverse carpal ligament is cut to release the median nerve

-Endoscopic carpal tunnel release surgery
Endoscopic surgery uses a thin, flexible tube with a camera attached (endoscope). The endoscope is guided through a small incision in the wrist (single-portal technique) or at the wrist and palm (two-portal technique). The endoscope lets the doctor see structures in the wrist, such as the transverse carpal ligament, without opening the entire area with a large incision.During endoscopic carpal tunnel release surgery, the transverse carpal ligament is cut. This releases pressure on the median nerve, relieving carpal tunnel syndrome symptoms.


Physiotherapy management :

-Resting the sore hand and wrist
-Activity modification
-Altering work practices
-Splinting
-Observe sleeping position.
-Exercises
Fully body stretches, forearm and wrist stretches, thumb and finger stretches as well as checking your posture and giving some relaxation techniques.

Acupuncture
insert thin needles into specifics point on the body.
Traditional theory holds blockages along energy pathways in the body, called meridians, can cause pain. Acupuncture releases these blockages and improves the flow of energy along meridians.
A scientific explanation is that acupuncture may release natural pain-relieving chemicals into the body, promote circulation in body, and balance the nervous system.
For carpal tunnel syndrome, acupuncture points are generally on the wrist, arm, thumb, and hands, as well as other parts of the body such as the upper back, neck, and leg.

Acupressure
Acupressure is based on the same principles as acupuncture. Instead of applying needles to acupuncture points, pressure is applied, which is thought to stimulate blood flow to the wrists and hands and ease numbness and swelling in the area.
Acupressure points for carpal tunnel syndrome are typically on the wrists, forearms and hands.

Vitamin B6
In several research studies, vitamin B6 deficiency has been associated with carpal tunnel syndrome. A typical dose of vitamin B6 for carpal tunnel syndrome is 50 mg 2 to 3 times a day.
Enzyme supplements such as bromelain or combination enzyme products (e.g. Wobenzym) may help to reduce tissue swelling
People who took homeopathic arnica tablets and arnica ointment had a significant reduction in pain after two weeks.


5) Yoga and Carpal Tunnel Syndrome

Yoga can help to reduce symptoms of carpal tunnel syndrome. A study by the University of Pennsylvania looked at the effectiveness of yoga for 42 people with carpal tunnel syndrome. People in the yoga group did 11 yoga postures twice weekly for 8 weeks and had a significant improvement in grip strength and pain reduction compared to people in the control group, who wore wrist splints.

6) Chiropractic and Carpal Tunnel Syndrome
Chiropractic may help to reduce symptoms of carpal tunnel syndrome and improve function. A study looked at chiropractic care vs. conservative care (ibuprofen and night-time wrist supports) in 91 people with carpal tunnel syndrome. Chiropractic care included manipulation of the soft tissues and body joints of the arms and spine, ultrasound over the carpal tunnel and night-time wrist supports. Researchers concluded that chiropractic was as effective as conventional care for carpal tunnel syndrome.

7) Feldenkrais
Feldenkrais is a form of movement re-education. People are taught individually or in group sessions how to move their bodies more efficiently to improve their co-ordination, reduce joint stress and muscle strain, and improve flexibility.

8) Hellerwork
Hellerwork is a form of bodywork that has three main components:
1. deep tissue work - treatment usually begins with work on the soft tissues around the forearm and wrist.
2. education about correct posture and movement, ergonomic assessment of the workstation (e.g. chair too low, monitor too high)
3. dialogue to address emotions that lock muscles into "holding patterns" and affect breathing.

What is Carpal Tunnel Syndrome ?

Video understanding of Carpal Tunnel Syndrome:

Causation and Prevalence

Causation

· Location: Hand

· Affect digits: Thumb ,index, middle, half of fourth

· Character: Numbness, pain, weakness, tingling.

· Cause: Compression of the Median Nerve.

Pathophysiology

· Occurs usually after bedtime.

· CTS is caused by compression on median nerve, due to edema or hypertrophy on the flexor synovium.

· Position of extreme flexion and extension are known to increase carpal tunnel stress and apply pressure to nerve.

Prevalence

· 3.8% of Malaysia general population is affected.

· Mostly middle age women

· Family susceptibility shows significant relationships. CTS family history known to be 9,84 [ 95% CI, 1.13, 85.83, P value 0.039) times the odds compared to those without (USM, 2008)

Sufficient Causation

  • Inflammation of the flexor tendon sheath caused by activities involving repetitive wrist flexion (eg, assembly packing, computer keyboard work, playing a musical instrument, craftwork)
  • Edema from trauma of any type (eg, fractures), which can compress the median nerve
  • Compression of the median nerve from pregnancy or oral contraceptive-related edema
  • Strong association between being overweight or obese and the presence of CTS
  • Acromegaly
  • Rheumatoid arthritis
  • Gout or pseudogout
  • Tuberculosis
  • Renal failure and hemodialysis
  • Hypothyroidism
  • Amyloidosis
  • Has been associated with diabetes mellitus


Ulnar nerve Lesion

Ulnar Nerve lesion
The ulnar nerve may be damaged at any point in its distribution. The most common sites are behind the elbow and in the hand.

The clinical features of an ulnar nerve lesion at the elbow include:
• wasting of the flexor carpi ulnaris and the ulnar half of the flexor digitorum:
-is apparent on the inner aspect of the flexor surface of the forearm
-weakness of flexor carpi ulnaris causes the hand to deviate to the radial side as the wrist is flexed
• wasting of the small muscles of the hand except the thenar eminence and the first two lumbricals
• clawing of the ring and little fingers (main en griffe):
-loss of the 3rd and 4th lumbricals and all the interossei results in:
-hyperextension of the metacarpophalangeal joints
-flexion of the interphalangeal joints
• paralysis of the hypothenar muscles:
-abolishes abduction of the little finger
• paralysis of the interossei:
-abolishes abduction and adduction of the fingers
• paralysis of the adductor pollicis:
-weakens adduction of the thumb which is most evident when a piece of paper is grasped in a pincer grip between thumb and index finger (Froment's sign)
• numbness and tingling:
-over the two ulnar fingers and the ulnar border of the palm

The clinical features of an ulnar nerve lesion below the elbow are presented according to the site of the lesion:
• in the cubital tunnel the features resemble those of a lesion at the elbow except:
-clawing is more prominent due to preservation of flexor digitorum profundus
-flexor carpi ulnaris is spared and so wrist flexion is unaffected
• at the wrist the features resemble those of a lesion at the elbow except:
-there is no sensory loss because the dorsal cutaneous branch of the ulnar nerve is spared
• in the hand the features resemble those of a lesion at the elbow except:
-the hypothenar eminence is usually spared
-wasting and weakness is confined to the interossei and adductor pollicis














Muscle and skin innervations of ulnar nerve
• Muscles:
o In the forearm, via the muscular branches of ulnar nerve:
-Flexor carpi ulnaris
-Flexor digitorum profundus (medial half)
o In the hand, via the deep branch of ulnar nerve:
-Hypothenar muscles
-Adductor pollicis
-The third and fourth lumbrical muscles
-Dorsal interossei
-Palmar interossei
o In the hand, via the superficial branch of ulnar nerve:
-Palmaris brevis
• Skin:
o The ulnar nerve also provides sensory innervation to the part of the hand corresponding to the fourth and fifth fingers:
-Palmar branch of ulnar nerve (anterior)
-Dorsal branch of ulnar nerve (posterior)
