Plantar fasciitis is the most common cause of pain on the bottom of the heel. Approximately 2 million patients are treated for this condition every year. Plantar fasciitis occurs when the strong band of tissue that supports the arch of your foot becomes irritated and inflamed. The plantar fascia is a long, thin ligament that lies directly beneath the skin on the bottom of your foot. It connects the heel to the front of your foot, and supports the arch of your foot.
Plantar fasciitis is caused by small, repetitive trauma to the plantar fascia. This trauma can be due to activity that puts extra stress on the foot. Plantar fasciitis is most common in people who are 40-60 years old. Other risk factors that increase your chance of getting plantar fasciitis include physical exertion, especially in sports such as running, Volleyball, tennis, a sudden increase in exercise intensity or duration, physical activity that stresses the plantar fascia. People who spend a lot of time standing, a sudden increase in activities that affect the feet, obesity or weight gain, pre-existing foot problems, including an abnormally tight Achilles tendon, flat feet, or an ankle that rolls inward too much. Poor footwear. Heel spurs.
Patients with plantar fasciitis typically experience pain underneath the heel and along the inner sole of the foot. In less severe cases, patients may only experience an ache or stiffness in the plantar fascia or heel that increases with rest (typically at night or first thing in the morning) following activities which place stress on the plantar fascia. These activities typically include standing, walking or running excessively (especially up hills, on uneven surfaces or in poor footwear such as thongs), jumping, hopping and general weight bearing activity. The pain associated with this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with this condition may also experience swelling, tenderness on firmly touching the plantar fascia (often on a specific spot on the inner aspect of the heel) and sometimes pain on performing a plantar fascia stretch.
A health care professional will ask you whether you have the classic symptoms of first-step pain and about your activities, including whether you recently have intensified your training or changed your exercise pattern. Your doctor often can diagnose plantar fasciitis based on your history and symptoms, together with a physical examination. If the diagnosis is in doubt, your doctor may order a foot X-ray, bone scan or nerve conduction studies to rule out another condition, such as a stress fracture or nerve problem.
Non Surgical Treatment
Shoe therapy, finding and wearing shoes that allow your feet to be in their natural position, is the most important treatment for plantar fasciosis. Shoes that possess a flat heel, are wide in the toe box, lack toe spring, and have flexible soles are most appropriate for this foot problem. An increasing number of shoe companies are producing shoes with these design characteristics, but shoes that include all these features are still difficult to find. For some suggested footwear models, see our clinic’s shoe list. Most conventional footwear can be modified by stretching the shoe’s upper, stretching out the toe spring, removing the shoe’s liner, and cutting the shoe at certain key points to allow more room for your foot. Visit your podiatrist to help you with these shoe modifications. Correct Toes is another helpful conservative treatment method for plantar fasciosis. Correct Toes addresses the root cause of your plantar fasciosis by properly aligning your big toe and reducing the tension created by your abductor hallucis longus on the blood vessels that feed and “cleanse” the tissues of your plantar fascia. Your plantar fasciosis-related pain will diminish when the dead tissue is washed away. A rehabilitation program, which includes targeted stretches and other exercises, for your foot may be helpful too. Dietary changes and aerobic exercise are particularly important for overweight individuals who have plantar fasciosis. Water aerobics may be most appropriate for those individuals whose pain does not allow them to walk or cycle. Physical therapy may be another helpful treatment modality for this problem, and includes ultrasound, electrical stimulation, contrast baths, and range-of-motion exercises. Massage, acupuncture, reflexology, and magnet therapy are holistic approaches that may be helpful.
In cases that do not respond to any conservative treatment, surgical release of the plantar fascia may be considered. Plantar fasciotomy may be performed using open, endoscopic or radiofrequency lesioning techniques. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. Potential risk factors include flattening of the longitudinal arch and heel hypoesthesia as well as the potential complications associated with rupture of the plantar fascia and complications related to anesthesia.
