The deep plantar fascia (plantar aponeurosis) is a thick, pearly-white tissue with longitudinal fibers intimately attached to the skin. Plantar fasciitis, characterized by pain in the plantar region of the foot that is worse when initiating walking, is one of the most common causes of foot and heel pain in adults. A large number of additional disorders can cause foot and heel pain. These include Achilles tendinopathy, Haglund’s syndrome, Stress fractures due to osteoporosis.
Plantar fasciitis can be confused with a condition called tarsal tunnel syndrome. In tarsal tunnel syndrome, an important nerve in the foot, the tibial nerve, is trapped and pinched as it passes through the tarsal tunnel, a condition analogous to carpal tunnel syndrome in the wrist. This may cause symptoms similar to the pain of a plantar fasciitis. There are also other less common problems such as nerve entrapments, stress fractures, and fat pad necrosis, all of which can cause foot pain. Finally, several rheumatologic conditions can cause heel pain. These syndromes such as Reiter’s syndrome and ankylosing spondylitis can cause heel pain similar to plantar fasciitis. If your symptoms are not typical for plantar fasciitis, or if your symptoms do not resolve with treatment, your doctor will consider these possible diagnoses.
Plantar fasciitis generally occurs in one foot. Bilateral plantar fasciitis is unusual and tends to be the result of a systemic arthritic condition that is exceptionally rare among athletes. Males suffer from a somewhat greater incidence of plantar fasciitis than females, perhaps as a result of greater weight coupled with greater speed and ground impact, as well as less flexibility in the foot. Typically, the sufferer of plantar fasciitis experiences pain upon rising after sleep, particularly the first step out of bed. Such pain is tightly localized at the bony landmark on the anterior medial tubercle of the calcaneus. In some cases, pain may prevent the athlete from walking in a normal heel-toe gait, causing an irregular walk as means of compensation. Less common areas of pain include the forefoot, Achilles tendon, or subtalar joint. After a brief period of walking, the pain usually subsides, but returns again either with vigorous activity or prolonged standing or walking. On the field, an altered gait or abnormal stride pattern, along with pain during running or jumping activities are tell-tale signs of plantar fasciitis and should be given prompt attention. Further indications of the injury include poor dorsiflexion (lifting the forefoot off the ground) due to a shortened gastroc complex, (muscles of the calf). Crouching in a full squat position with the sole of the foot flat on the ground can be used as a test, as pain will preclude it for the athlete suffering from plantar fasciitis, causing an elevation of the heel due to tension in the gastroc complex.
Diagnosis of plantar fasciitis is based on a medical history, the nature of symptoms, and the presence of localised tenderness in the heel. X-rays may be recommended to rule out other causes for the symptoms, such as bone fracture and to check for evidence of heel spurs. Blood tests may also be recommended.
Non Surgical Treatment
Stretching is the best treatment for plantar fasciitis. It may help to try to keep weight off your foot until the initial inflammation goes away. You can also apply ice to the sore area for 20 minutes three or four times a day to relieve your symptoms. Often a doctor will prescribe a nonsteroidal anti-inflammatory medication such as ibuprofen or naproxen. Home exercises to stretch your Achilles tendon and plantar fascia are the mainstay of treatment and reduce the chance of recurrence.
Surgery for plantar fasciitis can be very successful in the right patients. While there are potential complications, about 70-80% of patients will find relief after plantar fascia release surgery. This may not be perfect, but if plantar fasciitis has been slowing you down for a year or more, it may well be worth these potential risks of surgery. New surgical techniques allow surgery to release the plantar fascia to be performed through small incisions using a tiny camera to locate and cut the plantar fascia. This procedure is called an endoscopic plantar fascia release. Some surgeons are concerned that the endoscopic plantar fascia release procedure increases the risk of damage to the small nerves of the foot. While there is no definitive answer that this endoscopic plantar fascia release is better or worse than a traditional plantar fascia release, most surgeons still prefer the traditional approach.
