Your plantar fascia ligament helps the bones of your foot absorb gait-related shock. It also holds your toes firmly on the ground as your body passes over your foot. Plantar fasciosis can manifest in people who possess either flat feet or feet with high arches, and it most commonly causes pain or discomfort at the point where your plantar fascia attaches to your calcaneus, or heel bone. Plantar fasciosis, sometimes known as calcaneal spur syndrome or calcaneal enthesopathy, can involve stretching, tearing, and degeneration of your plantar fascia at its attachment site. In some cases, heel pain at this attachment site may be caused by other health problems, including certain types of arthritis. Your physician may run several tests to help determine the true cause of your plantar fascia pain and the most effective treatment methods to resolve your complaint.
Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body's weight, and the foot flattens and this places a great deal of pressure and strain on the plantar fascia. There is very little elasticity to the plantar fascia, so as it stretches only slightly; it pulls on its attachment to the heel. If the foot is properly aligned this pull causes no problems. However, if the foot is "pronated" (the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with "supination" (the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively in flexible; usually have a high arch, and a short or tight plantar fascia. Thus as weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel.
Plantar fascia usually causes pain and stiffness on the bottom of your heel although some people have heel spurs and suffer no symptoms at all. Occasionally, heel pain is also associated with other medical disorders such as arthritis (inflammation of the joint), bursitis (inflammation of the tissues around the joint). Those who have symptoms may experience ‘First step’ pain (stone bruise sensation) after getting out of bed or sitting for a period of time. Pain after driving. Pain on the bottom of your heel. Deep aching pain. Pain can be worse when barefoot.
Plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your plantar fasciitis they will investigate WHY you are likely to be predisposed to plantar fasciitis and develop a treatment plan to decrease your chance of future bouts. X-rays may show calcification within the plantar fascia or at its insertion into the calcaneus, which is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests (including screening for HLA B27 antigen) may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.
Non Surgical Treatment
Treatment of plantar fasciitis is sometimes a drawn out and frustrating process. A program of rehabilitation should be undertaken with the help of someone qualified and knowledgeable about the affliction. Typically, plantar fasciitis will require at least six weeks and up to six months of conservative care to be fully remedied. Should such efforts not provide relief to the athlete, more aggressive measures including surgery may be considered. The initial goals of physical therapy should be to increase the passive flexion of the foot and improve flexibility in the foot and ankle, eventually leading to a full return to normal function. Prolonged inactivity in vigorous sports is often the price to be paid for thorough recovery. Half measures can lead to a chronic condition, in some cases severely limiting athletic ability. As a large amount of time is spent in bed during sleeping hours, it is important to ensure that the sheets at the foot of the bed do not constrict the foot, leading to plantar flexion in which the foot is bent straight out with the toes pointing. This constricts and thereby shortens the gastroc complex, worsening the condition. A heating pad placed under the muscles of the calf for a few minutes prior to rising may help loosen tension, increase circulation in the lower leg and reduce pain. Also during sleep, a night splint may be used in order to hold the ankle joint in a neutral position. This will aid in the healing of the plantar fascia and ensure that the foot will not become flexed during the night.
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
