The plantar fascia is made up of 3 distinct parts: the medial, central, and lateral bands. The central plantar fascia is the thickest and strongest section, and this segment is also the most likely
to be involved with plantar fasciitis. In normal circumstances, the plantar fascia acts like a windlass mechanism to provide tension and support through the arch. It functions as a tension bridge in
the foot, providing both static support and dynamic shock absorption.
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position,
your abductor hallucis muscle-the muscle responsible for moving your big toe away from your footâs midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow
through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other
recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic
arthritis, Corticosteroid injections.
Among the symptoms for Plantar Fasciitis is pain usually felt on the underside of the heel, often most intense with the first steps after getting out of bed in the morning. It is commonly associated
with long periods of weight bearing or sudden changes in weight bearing or activity. Plantar Fasciitis also called âpolicemanâs heelâ is presented by a sharp stabbing pain at the bottom or
front of the heel bone. In most cases, heel pain is more severe following periods of inactivity when getting up and then subsides, turning into a dull ache.
After you describe your symptoms and discuss your concerns, your doctor will examine your foot. Your doctor will look for these signs. A high arch, an area of maximum tenderness on the bottom of your
foot, just in front of your heel bone. Pain that gets worse when you flex your foot and the doctor pushes on the plantar fascia. The pain improves when you point your toes down. Limited "up" motion
of your ankle. Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem. X-rays provide clear images of bones. They are useful in
ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray. Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not
routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.
Non Surgical Treatment
Anti-inflammatory agents used in the treatment of plantar fasciitis include ice, NSAIDs, iontophoresis and cortisone injections. Ice is applied in the treatment of plantar fasciitis by ice massage,
ice bath or in an ice pack. For ice massage, the patient freezes water in a small paper or foam cup, then rubs the ice over the painful heel using a circular motion and moderate pressure for five to
10 minutes. To use an ice bath, a shallow pan is filled with water and ice, and the heel is allowed to soak for 10 to 15 minutes. Patients should use neoprene toe covers or keep the toes out of the
ice water to prevent injuries associated with exposure to the cold. Crushed ice in a plastic bag wrapped in a towel makes the best ice pack, because it can be molded to the foot and increase the
contact area. A good alternative is the use of a bag of prepackaged frozen corn wrapped in a towel. Ice packs are usually used for 15 to 20 minutes. Icing is usually done after completing exercise,
stretching, strengthening and after a day's work.
When more-conservative measures aren't working, your doctor might recommend steroid shots. Injecting a type of steroid medication into the tender area can provide temporary pain relief. Multiple
injections aren't recommended because they can weaken your plantar fascia and possibly cause it to rupture, as well as shrink the fat pad covering your heel bone. Extracorporeal shock wave therapy.
In this procedure, sound waves are directed at the area of heel pain to stimulate healing. It's usually used for chronic plantar fasciitis that hasn't responded to more-conservative treatments. This
procedure may cause bruises, swelling, pain, numbness or tingling and has not been shown to be consistently effective. Surgery. Few people need surgery to detach the plantar fascia from the heel
bone. It's generally an option only when the pain is severe and all else fails. Side effects include a weakening of the arch in your foot.
