Plantar fasciitis is a painful inflammatory process of the plantar fascia, a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the five toes. Pain in the arch or heel often indicates inflammation of the long band of tissue under the foot (the plantar fascia). It can cause sharp pain and discomfort in either the mid arch region or at the inside heel, and less commonly the outside heel. It frequently causes pain upon rising from rest (especially first thing in the morning) and can progress to agony by the end of the day. Although plantar fasciitis is the most common cause of this pain, it must be skilfully differentially diagnosed from other conditions via a thorough history taking and physical examination.
This is a problem of either extreme, so people with high arches or those that have very flat feet are at risk of developing pain in this region. This is because of the relative stress the plantar fascia is put under. In people with excessive pronation, the plantar fascia is put under too much stretch, as their range flattens and strains it. People with a stiff, supinated (high-arched) foot lack the flexibility to appropriately shock absorb, so this too puts extra strain on the plantar fascia. Clinically, we see more people presenting with plantar fascia pain who have excessive pronation than those with stiff, supinated feet. But while the foot type is the biggest risk factor for plantar fasciitis, the whole leg from the pelvis down can affect how the foot hits the ground. A thorough biomechanical assessment will determine where in the kinetic chain things have gone wrong to cause the overload.
Heel pain is the most common symptom associated with plantar fasciosis. Your heel pain may be worse in the morning or after you have been sitting or standing for long periods. Pain is most common under your heel bone, but you also may experience pain in your foot arch or on the outside aspect of your foot. Other common signs and symptoms of plantar fasciosis include mild swelling and redness in your affected area, tenderness on the bottom of your heel, impaired ability to ambulate.
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
Plantar fasciitis treatment can be conservative (non-surgical) or invasive (surgical). Among the non-surgical ways to manage plantar fasciitis involves stretching and icing exercises. A night splint which help stretch the Achilles tendon and plantar fascia overnight, so that they can be more easily stretched during the morning. Orthotics that can be custom-made for the feet can also distribute tension on the feet more consistently. Corticosteroid is injected into the affected area to relieve pain and decrease inflammation. Doctors may also use extracorporeal shockwave therapy before considering plantar fasciitis surgery. During the therapy, sound waves are used to stimulate the affected area and eventually heal it. Physical therapy incorporation, deep massage stretching, and other modalities can at times be a helpful adjunct treatment. Surgery for plantar fasciitis is only considered when all other conservative treatments have failed.
Surgery is rarely used in the treatment of plantar fasciitis. However it may be recommended when conservative treatment has been tried for several months but does not bring adequate relief of symptoms. Surgery usually involves the partial release of the plantar fascia from the heel bone. In approximately 75% of cases symptoms are fully resolved within six months. In a small percentage of cases, symptoms may take up to 12 months to fully resolve.
Stretching the plantar fascia and the calf muscle area can help to prevent inflammation. Slowly increasing the amount or intensity of athletic activities by graded progression can also help to prevent injury. Recommended Stretches: Taking a lunge position with the injured foot behind and keeping your heels flat on the floor, lean into a wall and bend the knees. A stretch should be felt in the sole and in the Achilles tendon area. Hold the stretch for 20-30 seconds. Also try this stretch with the back leg straight.
