Plantar fasciitis is the most common cause of heel pain. Pain from plantar fasciitis is often most noticeable during the first few steps after getting out of bed in the morning. The plantar fascia is
a thick band of tissue in the sole of the foot. Microtearing at the origin of the plantar fascia on the heel bone (calcaneus) can occur with repetitive loading. This microtearing leads to an
inflammatory response (healing response) which produces the pain. Risk factors for plantar fasciitis include excessive standing, increased body weight, increasing age, a change in activity level, and
a stiff calf muscle. Plantar fasciitis can be managed non-operatively in the vast majority of patients. The main components of an effective non-operative treatment program are: calf stretching with
the knee straight, plantar fascia stretching, activity modification (to avoid precipitating activities), and comfort shoe wear.
There are a number of plantar fasciitis causes. The plantar fascia ligament is like a rubber band and loosens and contracts with movement. It also absorbs significant weight and pressure. Because of
this function, plantar fasciitis can easily occur from a number of reasons. Among the most common is an overload of physical activity or exercise. Athletes are particularly prone to plantar fasciitis
and commonly suffer from it. Excessive running, jumping, or other activities can easily place repetitive or excessive stress on the tissue and lead to tears and inflammation, resulting in moderate to
severe pain. Athletes who change or increase the difficulty of their exercise routines are also prone to overdoing it and causing damage. Another common cause of plantar fasciitis is arthritis.
Certain types of arthritis can cause inflammation to develop in tendons, resulting in plantar fasciitis. This cause is particularly common among elderly patients. Diabetes is also a factor that can
contribute to further heel pain and damage, particularly among the elderly. Among the most popular factors that contribute to plantar fasciitis is wearing incorrect shoes. In many cases, shoes either
do not fit properly, or provide inadequate support or cushioning. While walking or exercising in improper shoes, weight distribution becomes impaired, and significantly stress can be added to the
plantar fascia ligament.
The heel pain characteristic of plantar fasciitis is usually felt on the bottom of the heel and is most intense with the first steps of the day. Individuals with plantar fasciitis often have
difficulty with dorsiflexion of the foot, an action in which the foot is brought toward the shin. This difficulty is usually due to tightness of the calf muscle or Achilles tendon, the latter of
which is connected to the back of the plantar fascia. Most cases of plantar fasciitis resolve on their own with time and respond well to conservative methods of treatment.
If you see a doctor for heel pain, he or she will first ask questions about where you feel the pain. If plantar fasciitis is suspected, the doctor will ask about what activities you've been doing
that might be putting you at risk. The doctor will also examine your foot by pressing on it or asking you to flex it to see if that makes the pain worse. If something else might be causing the pain,
like a heel spur or a bone fracture, the doctor may order an X-ray to take a look at the bones of your feet. In rare cases, if heel pain doesn't respond to regular treatments, the doctor also might
order an MRI scan of your foot. The good news about plantar fasciitis is that it usually goes away after a few months if you do a few simple things like stretching exercises and cutting back on
activities that might have caused the problem. Taking over-the-counter medicines can help with pain. It's rare that people need surgery for plantar fasciitis. Doctors only do surgery as a last resort
if nothing else eases the pain.
Non Surgical Treatment
The following recommendations are appropriate. Wear shoes with adequate arch support and cushioned heels; discard old running shoes and wear new ones; rotate work shoes daily. Avoid long periods of
standing. Lose weight. Stretch the plantar fascia and warm up the lower extremity before participating in exercise. For increased flexibility, stretch the plantar fascia and the calf after exercise.
Do not exercise on hard surfaces. Avoid walking barefooted on hard surfaces. Avoid high-impact sports that require a great deal of jumping (eg, aerobics and volleyball). Apply ice for 20 minutes
after repetitive impact-loading activities and at the end of the day. Limit repetitive impact-loading activities such as running to every other day, and consider rest or cross-training for nonrunning
Plantar fasciotomy is often considered after conservative treatment has failed to resolve the issue after six months and is viewed as a last resort. Minimally invasive and endoscopic approaches to
plantar fasciotomy exist but require a specialist who is familiar with certain equipment. Heel spur removal during plantar fasciotomy has not been found to improve the surgical outcome. Plantar heel
pain may occur for multiple reasons and release of the lateral plantar nerve branch may be performed alongside the plantar fasciotomy in select cases. Possible complications of plantar fasciotomy
include nerve injury, instability of the medial longitudinal arch of the foot, fracture of the calcaneus, prolonged recovery time, infection, rupture of the plantar fascia, and failure to improve the
pain. Coblation (TOPAZ) surgery has recently been proposed as alternative surgical approaches for the treatment of recalcitrant plantar fasciitis.
