Plantar fasciitis is characterized by stiffness and inflammation of the main fascia (fibrous connective [ligament-like] tissue) on the bottom of the foot. It is occasionally associated with a bone spur on the heel. Occasionally there may be a partial or complete tear of the fascia of the bottom of the foot. Bone spurs themselves usually do not cause symptoms.
Far and away the most common cause of plantar fasciitis in an athlete is faulty biomechanics of the foot or leg. Faulty biomechanics causes the foot to sustain increased or prolonged stresses over and above those of routine ground contacts. Throughout the phase of ground contact, the foot assumes several mechanical positions to dissipate shock while at the same time placing the foot in the best position to deliver ground forces. With heel landing the foot is supinated (ankle rolled out). At mid-stance the foot is pronated (ankle rolled in). The foot is supinated again with toe-off. The supination of the foot at heel strike and toe-off makes the foot a rigid lever. At heel strike the shock of ground contact is transferred to the powerful quads. During toe-off forward motion is created by contraction of the gastroc complex plantar flexing the rigid lever of the foot pushing the body forward.
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.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
In many instances, plantar fasciitis can be treated with home care. Changing your physical activities, resting the foot, and applying ice to the area are common remedies. Taking over the counter medications such as ibuprofen or acetaminophen can help reduce pain and inflammation that may have developed. An orthotic device placed in your shoes can also significantly help to reduce pain. In addition, orthotics can also help promote healing to reverse plantar fasciitis. If pain from plantar fasciitis continues despite conservative treatments, you may need to visit a doctor or podiatrist. It’s important to seek medical advice before heel pain and damage becomes worse. If the condition is allowed to worsen, more serious or invasive forms of treatment may be required to stop pain. A visit to a doctor may reveal other conditions affecting the foot as well, such as Achilles tendonitis, heel spurs, or other heel pain conditions. An x-ray may also be taken, which can reveal the presence of a heel spur. In rare cases surgery may be required to release tension on the plantar fascia, or to remove a portion of a heel spur. But again, most heel pain conditions can be resolved using conservative treatment.
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.
Maintain a healthy weight. This minimizes the stress on your plantar fascia. Choose supportive shoes. Avoid high heels. Buy shoes with a low to moderate heel, good arch support and shock absorbency. Don’t go barefoot, especially on hard surfaces. Don’t wear worn-out athletic shoes. Replace your old athletic shoes before they stop supporting and cushioning your feet. If you’re a runner, buy new shoes after about 500 miles of use. Change your sport. Try a low-impact sport, such as swimming or bicycling, instead of walking or jogging. Apply ice. Hold a cloth-covered ice pack over the area of pain for 15 to 20 minutes three or four times a day or after activity. Or try ice massage. Freeze a water-filled paper cup and roll it over the site of discomfort for about five to seven minutes. Regular ice massage can help reduce pain and inflammation. Stretch your arches. Simple home exercises can stretch your plantar fascia, Achilles tendon and calf muscles.
