Plantar fasciitis is a painful inflammation of the plantar fascia, a fibrous band of tissue on the bottom of the foot that helps to support the arch. Plantar fasciitis occurs when this band of tissue is overloaded or overstretched. This causes small tears in the fibers of the fascia, especially where the fascia meets the heel bone. Plantar fasciitis is common in obese people and in pregnant women, perhaps because their extra body weight overloads the delicate plantar fascia. It is also more common in people with diabetes, although the exact reason for this is unknown. Plantar fasciitis also can be triggered by physical activities that overstretch the fascia, including sports (volleyball, running, tennis), other exercises (step aerobics, stair climbing) or household exertion (pushing furniture or a large appliance). In athletes, plantar fasciitis may follow intense training, especially in runners who push themselves too quickly to run longer distances. Worn or poorly constructed shoes can contribute to the problem if they do not provide enough arch support, heel cushion or sole flexibility.
When the foot moves, the plantar fascia stretches and contracts. Plantar fasciitis is caused by the repetitive overstretching of the plantar fascia. If the tension on the plantar fascia is too great, this overstretching causes small tears in the plantar fascia. This in turn causes the plantar fascia to become inflamed and painful. Factors that contribute to the development of plantar fasciitis include having very high arches or flat feet, gender, while anyone can develop plantar fasciitis, it tends to occur more commonly in women, exercises such as running, walking and dancing, particularly if the calf muscles are tight. Activities or occupations that involve walking or standing for long periods of time, particularly on hard surfaces, wearing high heeled shoes or shoes that do not offer adequate arch support and cushioning, being overweight, additional weight increases the tension on the plantar fascia, poor biomechanics, extra tension is placed on the plantar fascia if weight is not spread evenly when standing, walking or running. Some cases of plantar fasciitis may be linked to underlying diseases that cause arthritis, such as ankylosing spondylitis.
Symptoms of plantar fasciitis include pain in the heel of the foot. Some people complain of a sharp stabbing pain especially with walking. Others describe the pain as a dull ache after prolonged standing. The pain of plantar fasciitis is often worst in the morning or following activity.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
The plantar fascia is a band of tissue, much like a tendon, that starts at your heel and goes along the bottom of your foot. It attaches to each one of the bones that form the ball of your foot. The plantar fascia works like a rubber band between the heel and the ball of your foot to form the arch of your foot. If the band is short, you’ll have a high arch, and if it’s long, you’ll have a low arch, what some people call flatfeet. A pad of fat in your heel covers the plantar fascia to help absorb the shock of walking. Damage to the plantar fascia can be a cause of heel pain.
Surgery is considered only after 12 months of aggressive nonsurgical treatment. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage.
