The plantar fascia (a connective tissue structure) stretches from the toes and ball of the foot, through the arch, and connects to the heel bone in three places: outside, center and inside. Normally it helps the foot spring as it rolls forward. It also provides support for the arch of the foot. The plantar fascia helps keep the foot on track, cutting down on oscillation. When the foot over-pronates (rolls to the inside) the plantar fascia tries to stabilize it and prevent excessive roll. In time, the inside and sometimes center connections are overstressed and pull away from their attachments. The first sign is usually heel pain as you rise in the morning. When you walk around, the pain may subside, only to return the next morning. Inflammation and increased soreness are the results of long-term neglect and continued abuse. A heel bone spur may develop after a long period of injury when there is no support for the heel. The plantar fascia attaches to the heel bone with small fibers. When these become irritated they become inflamed with blood containing white blood cells. Within the white blood cells are osteoblasts which calcify to form bone spurs and calcium deposits. The body is trying to reduce stress on that area by building a bone in the direction of stress. Unfortunately, these foreign substances cause pain and further irritation in the surrounding soft tissue.
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 foot’s 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.
Plantar fasciitis is characterized by the following signs and symptoms. Acute plantar fasciitis, pain is usually worse in the morning but may improve when activity continues; if the plantar fasciitis is severe, activity will exacerbate the pain, pain will worsen during the day and may radiate to calf or forefoot, pain may be described anywhere from “minor pulling” sensation, to “burning”, or to “knife-like”, the plantar fascia may be taut or thickened, passive stretching of the plantar fascia or the patient standing on their toes may exacerbate symptoms, acute tenderness deep in the heel-pad along the insertion of the plantar aponeurosis at the medial calcaneal tuberosity and along the length of the plantar fascia, may have localized swelling. Chronic plantar fasciitis, plantar fasciitis is classified as “chronic” if it has not resolved after six months, pain occurs more distally along the aponeurosis and spreads into the Achilles tendon.
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
In general, plantar fasciitis is a self-limiting condition. Unfortunately, the time until resolution is often six to 18 months, which can lead to frustration for patients and physicians. Rest was cited by 25 percent of patients with plantar fasciitis in one study as the treatment that worked best. Athletes, active adults and persons whose occupations require lots of walking may not be compliant if instructed to stop all activity. Many sports medicine physicians have found that outlining a plan of “relative rest” that substitutes alternative forms of activity for activities that aggravate the symptoms will increase the chance of compliance with the treatment plan. It is equally important to correct the problems that place individuals at risk for plantar fasciitis, such as increased amount of weight-bearing activity, increased intensity of activity, hard walking/running surfaces and worn shoes. Early recognition and treatment usually lead to a shorter course of treatment as well as increased probability of success with conservative treatment measures.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
Every time your foot strikes the ground, the plantar fascia is stretched. You can reduce the strain and stress on the plantar fascia by following these simple instructions: Avoid running on hard or uneven ground, lose any excess weight, and wear shoes and orthotics that support your arch to prevent over-stretching of the plantar fascia.
