Knee Pain, Roosters and Osteoarthritis?

by Pain Doc | Mar 22, 2011 | Knee Pain

Osteoarthritis occurs when the cartilage lining the articulating (contacting) surfaces of a joint gets damaged or wears out, exposing nerve endings inside and leading to inflammation. Since a joint is a precision, biological mechanism the slightest change in any of its components will eventually lead to breakdown, much like car engine.

As the cartilage thins, bone on bone contact occurs. Since bone is living tissue, it will respond to this irritation by forming osteophytes, better known as bone spurs. The osteophytes compound the problem by disrupting proper joint movement and irritating surrounding ligaments. And to make matters worse, the joint fluid, called synovial fluid gradually loses its ability to cushion the joint. Synovial fluid to a joint is like motor oil to a car engine’s cylinder: it enables “near frictionless” movement. It forms a thin, lubricating buffer between the ends of the two bones that make up a joint; for example in the knee, the tibia (lower leg) and femur (upper leg).

The knee is perhaps the most common joint to experience osteoarthritis. It is a large, primary weight bearing joint that takes a lot of punishment in the course of a day. Basic activities like walking, running, going up stairs, stepping down from a curb, exercising, and sports really put the knees to task. Those who have advanced osteoarthritis in the knees realize how important they are to a normal life.

I ran across this treatment for knee osteoarthritis that involves a single injection that can last for six months. It is called Synvisc-One, and it’s made from the combs of roosters. Apparently, the substance found in rooster combs is similar in biochemical make up to that of synovial fluid. If you’ve ever pressed or bent a rooster’s comb, you can see why– it is soft, cushiony, and rebounds quickly to its original shape.

synvisc injection into the knee joint

The procedure is a relatively quick outpatient procedure. After filling out the necessary forms to ensure you have no contraindications, especially any known allergies to birds, the doctor injects the Synvisc into your knee joint using a large caliber needle. There, it occupies the capsular space just like motor oil occupies a car engine’s cylinder. The substance cushions the knee joint surfaces (distal femur-proximal tibia articulation) and lubricates the space to minimize abrasion of these surfaces.

Synvisc is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics, e.g., acetaminophen. It can be an option for total knee replacement for some people.

The drawback is that you have to keep getting them. But for those who have severe osteoarthritis in both knees and can’t afford or do not desire knee replacement surgery, six months of less pain is a pretty big deal. As with all forms of treatment options, a lot of it is personal choice. Not everyone’s situation is the same.

Treating Chronic Repetitive Strain Syndromes

by Pain Doc | Mar 19, 2011 | Sprains and Strains

If your job, hobby, or recreational activities involve repetitive movement patterns you may develop a repetitive strain injury, or RSI. Also known as overuse injuries, cumulative trauma disorders, and musculoskeletal disorders these types of conditions are characterized by pain, inflammation, swelling, and reduced joint movement.

Some of the more well-know causes of RSIs include:

typing/data entry (wrist tendonitis, epicondylitis)
hair styling (wrist tendonitis)
using vibrational tools (wrist, hand tendonitis)
carrying small children (deQuervain’s syndrome)
tennis (lateral epicondylitis; i.e. tennis elbow)
golf (medial epicondylitis; i.e. golfer’s elbow)
running (achilles tendonitis)
bowling (medial epicondylitis, wrist tendonitis)

RSIs mostly affect tendons, ligaments, bursae, and neural sheaths but they can affect muscle fibers as well. What happens is the offending activity places unusually high demand on these structures resulting in microscopic tears to the tissues. A very gradual inflammatory response follows, which then takes a life of its own. At this point the patient notices that the pain is more frequent and doesn’t go away with rest, and he/she may reach for an over the counter non-steroidal anti-inflammatory like Motrin.

What makes repetitive strain injuries so persistent is that they are caused by an activity the individual needs ( job) or loves (favorite sport) to do, and essentially he/ she “re-injures” the condition with the activity until it gets to an advanced stage.

Most of the time a repetitive strain injury is transient; i.e. it appears for several weeks then disappears. The patient resorts to icing, rest, temporary discontinuation of the offending activity, over the counter meds, massage therapy, bracing, and in some cases, cortisone shots.

In some people, the pain turns chronic; i.e. doesn’t entirely go away even after weeks and months since the onset. If you are experiencing this, it can be due to improperly healed microtears causing abnormal muscle and tendon performance; and perhaps trigger points which are believed to be concentrations of nerve endings at an old injury site.

When the condition is chronic, you can attempt to do the therapy in the video above. You use a flat edged massage instrument to “strip” the muscle close to where it attaches to the joint. This can help loosen any fibrous adhesions (“stickiness”) that may be interfering with muscle and tendon movement. It also mildly agitates the area (be careful not to overdo it) and increases blood flow, which can stimulate repair by fibroblasts, special cells that synthesize collagen.

This therapy is not to be done when the condition is acute (recent onset, hot, red, swelling). Doing so will make it worse. Try it only when it has reached a chronic stage and inflammation is absent. If it causes an unusual increase in pain, discontinue and apply ice.

Burt’s Bees Res-Q Ointment for Minor Injuries

by Pain Doc | Feb 17, 2011 | Uncategorized

Today, a patient of mine returned from a trip to Australia. She relates how her vacation was interrupted by the recent flooding in that country, and by something else– a nasty spider bite.

Now, if you’ve ever watched Discovery Channel and saw one of those nature shows on extreme insects, you’ll know that many come from Australia. There’s something about that country, perhaps its isolation that makes it a haven for dangerous, poisonous creatures.

Anyways, this patient says she was bitten on the leg by a black spider (probably a funnelweb spider). She said she “saw” the poison slowly work its way up her leg towards her knee (there was probably some reddening/ inflammation that spread outwards from the spider bite). Her companion told her not to move her leg, as it would spread the poison faster. Panicking, she took out the only first aid item she had on her– a small tin of Burt’s Bees Res-Q ointment— and rubbed it around the spider bite.

Almost instantly, she started to feel relief. An hour or so later, the swelling was gone. She said that the product literally “saved her life.” She was absolutely thrilled, from not knowing whether she would die from this bite, to feeling much better in a matter of minutes. She couldn’t say enough good things about the Res-Q ointment, and made sure I knew about it.

Curious, I decided to check it out. The main ingredient in Res-Q is comfrey, a controversial herb that has shown to have therapeutic benefits, but may also cause liver toxicity if taken internally. Comfrey contains allantoin, a cell proliferant that speeds up the natural replacement of body cells.

Historically, comfrey was used in an attempt to treat a wide variety of ailments ranging from bronchial problems, broken bones, sprains, arthritis, gastric and varicose ulcers, severe burns, acne and other skin conditions. It was reputed to have bone and teeth building properties in children, and have value in treating “many female disorders”.

Most recently, in a placebo controlled study comfrey was found to decrease back pain when used topically.

If you visit the Burt’s Bees website and check out their Res-Q product, you will notice a lot of positive reviews– people raving about how the product helped reduce the “red nose of colds,” bruises, skin irritations, minor burns, bug bites, and cracked and chapped skin.

While these reviews are no substitute for a properly conducted scientific study with control group, most doctors agree that anecdotal evidence can be equally compelling when evaluating a particular therapeutic product or procedure.

Now, time to sign off to buy a can of Res-Q myself…

What is Causing My Heel Pain?

by Pain Doc | Sep 7, 2010 | Foot and Ankle Pain

Heel pain can be caused by a number of factors. One of the most common is a heel spur, medically referred to as a calcaneal spur.

A heel spur is an outgrowth of bone in the shape of a small spire. If it’s at the bottom or side of the heel bone (calcaneous), it can be painful to walk. It is thought that heel spurs form as a result of stress on a tendinous insertion into to the heel, but some heel spurs aren’t associated with the area where a tendon inserts into the heel.

Whenever offshoots of bone form (bone spurs), it is due to a history of stress to the bone, either gradual formation following a single impact trauma such as a car accident; or cumulative impact forces over time, such as from sports. For the foot bones, an example of the latter would be years of playing basketball or ballet dancing. The repetitive pounding on the joints of the foot can cause bone cells at the impact area to secrete more bone matrix as a compensatory response. In the spine and large weight bearing joints (knee, hip) they are called osteophytes.

In some cases, the heel spur stops producing pain; perhaps due to resorbption or even callous formation neutralizing its ability to press against tissue. For those that don’t, surgery can be done by a podiatrist or orthopedic surgeon to smooth down the heel spur.

TREATMENT:

In the meantime, avoiding impact trauma to the heel is important (running, jumping). You can buy special shoe inserts that help reduce pressure on the heel spur. Comfortable shoes are a must as well; make sure they are wide and have a thick rubber, shock absorbing sole. The Z-Coil shoe brand incorporates a large spring at the heel to minimize shock/ impact forces to the foot when walking.

Sitting in a chair and rolling a cold beer or soda can (unopened) under your foot can help stretch the foot and ease some of the pain. A golf ball can provide more focused massage to the bottom of the foot. Press downward with enough pressure to get a good stretch and massage, but not so much to increase the heel pain.

Lastly, consider exercising your feet by walking barefoot around the house and outside (walking barefoot indoors is not as effective due to the flatness of the floor; bumpy and uneven is better). Walking in shoes actually weaken the foot over time by preventing the intrinsic foot muscles and joints from exercising and experiencing their full range of motion. You can also consider getting the Vibram foot glove. This interesting shoe fits on your foot like a glove, allowing some independent movement of the toes.

Plantar fascitis is a condition where the plantar fascia (a wide, band-like ligament connecting the heel to the forefoot) pulls off a thin layer of periosteum (membrane lining the bone) from the heel and results in inflammation and pain at the front, bottom part of the heel. It can make walking very uncomfortable.

The best approach to treating plantar fascitis is to rest your foot for a few days: no running, no walking up hill; walk only on flat surfaces. Use Red Light Therapy and Pulsed EMF for 15 minutes, twice a day for 2-3 weeks to accelerate healing of tissues, and for reducing any inflammation that is causing pain. Red light therapy uses photobiomodulation to accelerate cell metabolism; thus accelerating healing of tissues.

Compression fractures and hairline (stress) fractures can also cause heel pain. If you think you’ve fracture your heelbone, have it X-rayed. You’ll likely get a foot cast, avoid impact to the heel for several months, and wait until the fracture heals (no pun intended).

If your heel bone fractures easily, it could be due to a bone cysts. See your doctor on solutions for dealing with bone cysts.

When You Get Whiplash Neck Pain from a Car Accident

by Pain Doc | Aug 26, 2010 | Neck Pain, Sprains and Strains

Ever get rear-ended while waiting in traffic or at a stop sign? It’s a scary moment: the calmness of being out in your car is viciously interrupted by screeching tires and a loud crash and bending metal. It’s over in two seconds, but a lot happens to your body in that one second.

If a high speed camera was available to record your mishap, it would show your body violently moving forward with the car, back sinking into your car seat, your head slowly arching backwards at an unnatural angle; your neck muscles tense up; your head coming to a stop in its backwards path and then reversing directions to move forward again, through a complete arc until your neck is fully flexed forward in an unnatural position; coming to a stop again, and then reversing directions and fully extending a few degrees less than before, and then reversing and flexing forward again, then righting itself. That is your basic whiplash injury.

You’ll notice your neck become stiff, but very gradually. You may be a bit dazed, and have a headache come on in about an hour. You’ll likely feel tired.

As the day wears on, your neck is getting increasingly stiff and painful. You may feel the onset of soreness in your upper shoulders and upper back; even your lower back. You may have pain in your chest wall where the seatbelt dug into.

2-3 days after the accident your neck will reach maximum stiffness. You will have difficulty turning your neck. You’ll find yourself turning your whole body in order to see to one side.

So what is happening? You have sustained what’s called a cervical acceleration-deceleration sprain strain injury; commonly known as whiplash. Car accidents are a common cause of whiplash, but they can occur on roller coasters and similar jerky rides, horse riding, sky diving, and even wild dancing. When this happens, tiny tears develop in the muscle tissue and fascia (muscle covering) which starts to release the inflammatory products of swelling. The swelling is gradual, like a pinhole leak, which explains why it takes 2-3 days to reach max pain. What makes a whiplash worse than other sprain strain injuries is that, due to the flexibility of the neck, spinal ligaments also incur damage.

When your neck flexed violently forward, the capsular ligaments and interspinous ligaments likely got damaged. The capsular ligaments hold your neck bones together from the back; the interspinous ligaments hold them together at the spinous processes (the bumps you feel along your spine are the tips of the spinous processes).

interspinous ligament rupture

When these ligaments injure, the swelling goes inside the joint space, building up pressure essentially splinting (immobilizing) the joint. In severe cases, the ligaments can rupture (tear) causing dangerous instability, and you have a very serious condition that requires a visit to the ER. A head halo support or neck brace is usually attached to prevent the instability from causing damage to your spinal cord.

TREATMENT:

Obviously, it’s a good idea to go to the hospital if you were involved in a significant car accident and feel you’ve been injured. The ER doctor will rule out serious conditions like ligament rupture, bleeding in the brain (subdural hematoma), and bone fractures. Once those are ruled out, he/she will diagnose you as having a sprain strain injury and will usually prescribe pain meds (anti inflammatories and muscle relaxants). You will be given home care instructions.

With whiplash, the goal is to first reduce the pain and swelling. You will do this by applying an ice pack to your neck. Here’s a YouTube video on Whiplash Home Care – icing and stretches that illustrates the information to follow.

Buy two gel ice packs at your local drugstore (9″ x 6″ size); put in freezer. Make a cervical roll using a small bath towel or hand towel: roll it up tightly into a cylinder 1′ long with a radius of five inches. Place it on the floor.

Place one ice pack on top of the roll, and one right under (next) to it. Put a kitchen towlette on top of the ice to prevent iceburn. Lie down, face up with the center of the back of your neck on top of the cervical roll/ice pack. The other ice pack is for your upper back muscles. Put a pillow under your knees for comfort, dim the lights and rest for 20 minutes. Repeat this every two hours, for 2-3 days.

On the second day, while icing slowly turn your neck to the right as far as you can, then to the left, then to center. Then, arch your neck and touch the carpet with the crown of your head and hold for 20 seconds. Repeat these motions ten times. Do this for each of your icing session, still at 20 minutes every 2 hours. This helps to regain full neck range of motion.

On the 4th day, alternate ice with 10 minutes of moist heat using a hot water bottle with 150 degree water heated on your stove, and a wet face towel for heat conduction, on your neck and back muscles.

As the pain decreases, engage in active stretching exercises. About two weeks post crash, or when the pain has gone down 90% and you have full range of motion in your neck, do neck strengthening exercises. It is important to do these rehab exercises as they help align the reparative tissue in the axis of contraction of the muscles. This will help reduce the chances of chronic pain and loss of range of motion following the accident.

Since the original publication of this article, I’ve researched a new modality called Pulsed Electromagnetic Field therapy, or Pulsed EMF, or PEMF for short. The link explains it in detail, but basically it is the external application of low frequency, low amplitude electromagnetic fields, similar to the natural EM fields your body produces, to impart energy to them. EM fields are used to drive movement of molecules in and out of the cells, which includes nutrients, waste products, proteins and other factors involved in life processes. When cells are sick or injured, this process is not efficient. Pulsed EMF imparts a boost of energy (in fact, it is considered “Energy medicine”) which helps injured/sick cells perform their biological functions more efficiently, promoting accelerated healing and improved symptoms (less pain).

Apply PEMF to your neck three times a day for 15 minutes, for 2-3 days following the accident. You should experience a noticeable reduction in pain each time, an hour or so after treatment.
