Plantar fasciitis is sometimes mixed up with a heel spur although they are not the same. A heel spur is a calcium deposit that occurs where the plantar fascia is attached to the heel bone (calcaneus). In many cases a heel spur is found on a foot with no pain or other symptoms at all. And in many painful heels there is no sign for a heel spur. Heel spur and painful heal does not necessarily go together. For many years plantar fasciitis was believed to be an inflammatory condition. It is thought now to be inaccurate because there were many cases of the disorder with no inflammatory signs observed within the fascia. The heel pain cause is now believed to be damage to the collagen fibers of the fascia. This damage, caused by stress injury, sometimes may include inflammatory cells.
Plantar Fasciitis is frequently cited as the number one cause of heel pain. The condition affects both children and adults. Children typically outgrow the problem, but affected adults may experience recurring symptoms over the course of many months or years. The syndrome afflicts both highly active and sedentary individuals. Typically, Plantar Fasciitis results from a combination of causes, including, pronation, a condition in which the plantar fascia doesn’t transfer weight evenly from the heel to the ball of the foot when you walk. Overuse of the feet without adequate periods of rest. High arches, flat feet or tightness in the Achilles’ tendon at the back of the heel. Obesity. Working conditions that involve long hours spent standing or lifting heavy objects. Worn or ill-fitting footwear. The normal aging process, which can result in a loss of soft tissue elasticity. Physical trauma to the foot, as in the case of taking a fall or being involved in a car accident.
The pain associated with plantar fasciitis is typically gradual in onset and is usually located over the inner or medial aspect of the heel. Occasionally, the pain will be sudden in onset, occurring after missing a step or after jumping from a height. The pain is commonly most severe upon arising from bed in the morning, or after periods of inactivity during the day. Thus, it causes what is known as “first-step pain.” The degree of discomfort can sometimes lessen with activity during the course of the day or after “warming-up”, but can become worse if prolonged or vigorous activity is undertaken. The pain is also often noted to be more severe in bare feet or in shoes with minimal or no padding at the sole.
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
If conservative treatments fail, and the symptoms of plantar fasciitis have not been relieved, the doctor may recommend one of the following treatments. Cortisone, or corticosteroids, is medications that reduce inflammation. Cortisone is usually mixed with local anesthetics and injected into the plantar fascia where it attaches to the heel bone. In many cases this reduces the inflammation present and allows the plantar fascia to begin healing. Local injections of corticosteroids may provide temporary or permanent relief. Recurrence of symptoms may be lessened by combining steroid injections with other forms of treatment such as orthotics, changes in shoe gear, weight loss, stretching exercises, and rest. Repeated cortisone injections may result in rupture of the plantar fascia, thinning of the heel’s fat pad, and other tissue changes. Extracorporeal Shock Wave Therapy (ESWT) devices generate pulses of high-pressure sound that travel through the skin. For reasons that are not fully understood, soft tissue and bone that are subjected to these pulses of high-pressure energy heal back stronger. There is both a high-energy and low-energy form of ESWT; and both forms of shock wave therapy can be used in the treatment of plantar fasciitis. Research studies indicate ESWT is a safe and effective treatment option for plantar fasciitis. The recovery period is shorter than traditional invasive surgery and the procedure eliminates many of the risks associated with traditional surgery.
Surgery may be considered in very difficult cases. Surgery is usually only advised if your pain has not eased after 12 months despite other treatments. The operation involves separating your plantar fascia from where it connects to the bone; this is called a plantar fascia release. It may also involve removal of a spur on the calcaneum if one is present. Surgery is not always successful. It can cause complications in some people so it should be considered as a last resort. Complications may include infection, increased pain, injury to nearby nerves, or rupture of the plantar fascia.
