Heel Pain – By: William P. Rix, MD

Posted on February 18, 2014.

There are two types of heel pain that send patients to the orthopedist:  back of the heel pain (Achilles Tendinitis or AT) and bottom of the heel pain (Plantar Fasciitis or PF). The symptoms in both conditions are similar:  first step, or start up, pain after getting out of bed in the morning and pain after getting up from prolonged sitting. After a few steps, the pain lessens, but with increased activity through the day it worsens. Usually only one heel is involved, and there is no pain at rest.

The cause is similar in both syndromes. The Achilles tendon (heel cord) attaches the lower calf muscle to the back of the heel bone.  Pain in the back of the heel (Achilles Tendinitis) is due to a breakdown of this attachment.The Plantar Fascia is a ligament which attaches the toes to the bottom of the heel bone and supports the arch.  Pain at the bottom of the heel (Plantar Fasciitis) is due to a breakdown in this attachment.

The culprit, in many cases, is an over tight Achilles tendon which places extra stresses on attachments to the heel bone.  Over time the attachment frays and the body`s effort to repair it stalls.

  • A tight Achilles tendon places direct stress on its own attachment at the back of the heel bone which can cause Achilles Tendinitis.
  • A tight Achilles tendon also can cause Plantar Fasciitis: if the Achilles is tight the foot resists bending upwards during normal walking and running, thus placing additional stress on the plantar fascia as it tries to compensate for the tight Achilles by flexing more than usual.  This stress is concentrated at its attachment on the bottom of the heel.

It is the resultant non healing state of the tendon or the fascia (both termed “tendinopathies”) that causes the chronic heel pain. (Interestingly, these two conditions do not coexist at the same time). Usually the patient endures months of suffering, hoping the problem will resolve, before seeking medical help.

Our goal in treatment is to try and “jump start” the healing process.  We use physical therapy, anti-inflammatory medication, shoe inserts, daily heel cord and plantar fascia stretching exercises, and night splints that stretch these soft tissues during sleep.  High impact sports are curtailed and behaviors detrimental to healing (smoking, poor nutrition, unsupportive foot wear, excess weight) are addressed.

Steroid injections into the heel cord and plantar fascia are used sparingly, if at all.  They delay local healing and may weaken the tissues, predisposing them to rupture.  Injections of Platelet Rich Plasma (PRP), a spun down concentrate of a person’s own blood, have been used to treat these conditions. Though considered experimental and somewhat controversial, PRP injections have been shown in some cases to accelerate healing.

Occasionally surgery is used, but more with Achilles Tendinitis than Plantar Fasciitis. (Making an incision in the skin over the back of the heel is much better tolerated than going through the very thick skin and fat pad on the bottom of the heel).  Sometimes all it takes to restart healing is to remove surgically the non-healing tissues from the Achilles` or Plantar Fascia`s bony attachments.   In other cases, the Achilles tendon may need to be detached, cleaned off, and reattached into a new freshened bed of bleeding bone. This is not done with the plantar fascia for reasons stated above and because the results are less predictable.

Once the AT or PF has resolved, whether through conservative or surgical means, it is important for the patient to be on a maintenance program to prevent recurrence. A one hour program of stretching and brisk walking at least three times a week is highly recommended. Stretching is particularly important because healing tissue(scar) tends to shorten and tighten with time, rendering it more vulnerable to re-tearing.

Other causes of heel pain include stress fractures, pinched nerves, infections, arthritis, and tumors.  Although these conditions are always kept in mind when assessing the cause of a patient`s chronic heel pain, they are uncommon.  When the diagnosis is AT or PF, early treatment ensures the best possible outcome from these two common, but debilitating conditions that interfere greatly with an active lifestyle, so important to  general health and wellness.

Knee Cap Pain – By: William P. Rix, MD

Posted on November 5, 2013.

Knee Cap Pain

Knee pain is a common complaint in patients presenting to the orthopedist. The kneecap is often the culprit. To understand why this bone plays such a prominent role in knee pain, a review of anatomy is in order.

The knee cap, known as the patella, is a fig newton size bone, triangular in cross section and located at the end of the quadriceps, the powerful muscle-tendon structure that runs down the front of the thigh and is responsible for extending the lower leg.

When our knee bends, the patella slides into a groove in the front of the femur (the   thigh bone) called the patello-femoral groove. This V shaped groove perfectly matches the two sides of the triangular (V-shaped) patella. When the quadriceps contracts, pulling the lower leg to the straight (i.e. extended) position, the undersurface of the kneecap is subjected to compression stresses (pressure):  the stronger the contracture (intensified in running or stair climbing, for example), the greater the stress.

The knee joint, like all joints in the body, is lined with a smooth, slippery white material called cartilage.  The cartilage on both sides of the patella-femoral joint can tolerate the high pressures of intense quadriceps activity if the patella glides in the groove perfectly centered, thereby absorbing equally the compression stresses on both of its V-shaped sides (facets).  And, “therein lies the rub”.

For the patella to stay perfectly centered in the groove during activity, many things have to be in place: the pull of the quadriceps has to be equal (symmetrical) on both sides of the patella; the rotation of the thigh must be aligned with that of the lower leg; the muscles around the knee, foot and ankle must be balanced and strong enough to perform their function; and the individual muscles in the entire leg must be of the right tension, not too tight and not too loose.

If the forces around the patella and the whole limb are not balanced, the patella glides asymmetrically in the groove (i.e. slips out of place) during quadriceps contracture predominantly loading one (usually the outside i.e. lateral) facet over the other. This concentrated pressure over just half the usual surface area causes the cartilage to fail resulting in pain, buckling and stiffness. If this continues unchecked, arthritis occurs.

Often a person has a slipping patella, but doesn’t know it. The knee has no symptoms because the person’s lifestyle does not include activities with intense demands on the quadriceps.  The knee remains symptom free as long as the activities of daily living (ADL) are not stressful enough to cause symptoms.

All is well until the person embarks on a new activity (running, biking, hiking, lifting, etc.) that markedly increases the load on the knee.  This new load is concentrated on the slipping patella and is more than a single lateral facet can bear.  Pain occurs in the front of the knee and occasionally behind the knee. Simple every day activities like squatting, climbing stairs and getting up from a chair now are painful.  Swelling, cracking and stiffness become daily occurrences. It is at this point the patient seeks medical help.

Orthopaedic treatment must be tailored to the specific mechanical abnormality, with the goal being to balance the forces acting on the patello-femoral joint so that the patella remains centered in the femoral groove during quadriceps contracture. Conservative therapy involving physical therapy, orthotics, and bracing (individually or in combination) is successful in most cases.  When rehabilitation efforts fail, surgery is used to balance the forces around the kneecap so that the patella stays in its groove.

When a patient`s chief complaint is knee pain, orthopedists must first find the site of the pain and then the reason it exists. When the pain site is the knee cap, we must identify the mechanical abnormalities, educate the patient as to why they exist and then correct them with rehabilitation and, if necessary, surgery. This, plus a lifelong commitment by the patient to a maintenance exercise program gives us our best chance at a successful and lasting outcome.

Recommended: A Healthy Orthopaedic Lifestyle – By: William P. Rix, MD

Recommended: A Healthy Orthopaedic Lifestyle

Strains, sprains, overuse injuries, fractures, and arthritis: it`s a rare person who has not experienced one of these orthopaedic problems.
Practicing good orthopaedic health habits can minimize the risk of incurring one or more of these common musculoskeletal conditions.

Exercise
Strong muscles protect our joints from injury by absorbing the energy of impact and torsion. Also, a strong muscle with its attached tendon is less likely to tear, a condition that can lead to painful tendinopathy(1) such as “tennis elbow” or shoulder bursitis.

Aerobic activity that elevates your heart rate for at least 20 minutes a day is recommended for strengthening muscles. My favorite is brisk walking with two walking poles (2), because all four extremities are engaged in weight bearing exercise which is important for improving muscle and bone strength. Excellent substitutes for walking include swimming, riding a stationary bike or using an elliptical trainer.

Aging increases our need for regular exercise as the body`s “fitness memory” becomes shorter and shorter. Exercise more as you age, not less.

Stretching
As we get older, our joints and muscles get stiffer. Stiffness lowers the threshold for incurring sprains, strains and tendon inflammation (“tendinitis”). A daily stretching program not only feels good, but minimizes the risk of injury by maintaining flexibility. A simple, but reasonably comprehensive program can be accomplished in 10 minutes (3).

Weight Control
Obesity is strongly liked to arthritis, not only mechanically (extra weight on joints), but also biochemically (fat cells secrete joint damaging inflammatory substances). A weight control plan I recommend includes eating three balanced meals a day with portion control, no snacking, and avoidance of processed foods and sugary drinks.

Smoking and Alcohol
Smoking and heavy drinking are both risk factors for fracture non-union, poor wound healing and osteoporosis. Stop smoking and drink only in moderation.

Calcium and Vitamin D
Vitamin D and Calcium are essential for optimal bone and muscle health. Adults should ingest 1200 mg of calcium (diary, supplements) and 800 IU of Vitamin D (supplements) per day.

Beware of “New” Sport or Activity Participation
Intense use of muscle groups that are not conditioned is an invitation for overuse injuries and tendinitis.

Daily exercise on the stationary bike, for instance, does not mean you are ready to play a game of racquetball, climb Mt Washington or even paint the kitchen.

Start slowly, identify the new muscle groups required for the activity and stretch and strengthen them regularly. The duration of this preparation phase will vary with your age, baseline fitness and type of desired activity, but plan on spending a few weeks to months in training before unrestricted participation.

Good Driving Habits
Motor vehicle accidents are a frequent cause of musculoskeletal injuries, many of them devastating. Minimize your risk by obeying traffic laws, wearing your seat belt, and avoiding distractions like texting. Never drive while intoxicated.

When an accident or arthritis happens, it is often viewed as just “bad luck”, but there is something to the old adage, “you make your own luck”. Practicing a healthy orthopaedic lifestyle minimizes the risk of musculoskeletal injury and prevents or at least lessens the debilitating symptoms of osteoarthritis.

Pain in the Butt! – By William P. Rix, MD

Posted on June 6, 2013.

Hip girdle pain is defined as pain in the buttock that radiates into the thigh.  It is a common problem, particularly in the older person. Although there are many possible causes of this condition, most are found to be  degenerative disease of the hip joint (osteoarthritis), the lumbar spine (facet arthritis, lumbar stenosis) or the buttock tendons (tendinopathy, “trochanteric bursitis”) at their attachment to the greater trochanter, the bony bump just forward of one`s pants pocket.

The history given by the patient is often similar in the three conditions:  pain in the buttock radiating into the thigh and sometimes into the outer leg below the knee. This pain typically worsens with activity and improves with rest. The physical exam, though occasionally diagnostic, more often is non-specific, failing to implicate one specific area of pain generation more than another.

X-ray and MRI are often employed in the diagnostic testing and are excellent at showing degenerative disease of the hip and spine and, to a lesser extent, the tendons.  Positive findings on the films, however, do not provide a definitive diagnosis, as those degenerative changes may be simply age related and not causing any of the symptoms experienced by the patient.

At this point in the systematic search for a diagnosis, the orthopedist must answer several questions:

  • Do the arthritic changes seen on x-ray and MRI play any role in the patient’s symptom production?
  • Is there one site that is the primary pain generator and are the other pain producing sites merely secondary (“compensatory”*) or are there two or more sites equally responsible for producing the pain?
  • What additional diagnostic testing would provide the most information with the least risk?  

To answer these questions we often turn to steroid/anesthetic injections in our quest for a specific diagnosis.  The three sites of injection are the hip joint (osteoarthritis), the lumbar spine (facet arthritis, lumbar stenosis) and the greater trochanter (tendinopathy, trochanteric bursitis).   We begin our injection sequence at the site that is the prime suspect and wait for several days to properly gauge a response.  If the response is a 50% reduction in pain then injecting the other two sites is unnecessary, as the prime pain generator has been identified. If the injection response is equivocal we move on to the second site, and if that too is indecisive, on to the third. In the rare event that all three are non-diagnostic, we expand our search to include uncommon causes of hip girdle pain.

Once we have our diagnosis, the treatment is focused on that condition. Effective treatment for the primary condition often markedly diminishes the symptoms from the secondary sites.

Treatment for all three conditions initially involves physical therapy, each program tailored to the specific pathology or abnormality.  In many cases, the injection used for diagnosis is therapeutic as well as diagnostic, with pain relief lasting months.  

Sometimes conservative treatment yields only short-term relief. In these situations, depending on the diagnosis, total hip replacement for osteoarthritis or decompression of the lumbar spine for lumbar stenosis yields very good to excellent results. Surgery for trochanteric bursitis is less common, but would involve repair of a tear, if present, of the buttock tendons attachment to the greater trochanter.

“Pain in the butt” is a popular cliché with good reason, for the complaint is common and the symptoms annoying. The list of possible causes of hip girdle pain is long and complex, and making the diagnosis can be both challenging for the orthopedist and frustrating for the patient. Fortunately, most hip girdle pain is due to common degenerative changes about the hip and low back, conditions for which treatment is available and rewarding.

* This term refers to the overuse of a muscle that is compensating for the underuse of the injured area.
