What Causes Plantar Fasciitis To Surface
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.
You're more likely to develop the condition if you're female, overweight or have a job that requires a lot of walking or standing on hard surfaces. You're also at risk if you walk or run for exercise, especially if you have tight calf muscles that limit how far you can flex your ankles. People with very flat feet or very high arches also are more prone to plantar fasciitis.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as arthritis , or a nerve problem such as tarsal tunnel syndrome.
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
In general, we start by correcting training errors. This usually requires relative rest, the use of ice after activities, and an evaluation of the patient's shoes and activities. Next, we try correction of biomechanical factors with a stretching and strengthening program. If the patient still has no improvement, we consider night splints and orthotics. Finally, all other treatment options are considered. Non-steroidal anti-inflammatory medications are considered throughout the treatment course, although we explain to the patient that this medicine is being used primarily for pain control and not to treat the underlying problem.
Plantar fasciotomy is often considered after conservative treatment has failed to resolve the issue after six months and is viewed as a last resort. Minimally invasive and endoscopic approaches to plantar fasciotomy exist but require a specialist who is familiar with certain equipment. Heel spur removal during plantar fasciotomy has not been found to improve the surgical outcome. Plantar heel pain may occur for multiple reasons and release of the lateral plantar nerve branch may be performed alongside the plantar fasciotomy in select cases. Possible complications of plantar fasciotomy include nerve injury, instability of the medial longitudinal arch of the foot, fracture of the calcaneus, prolonged recovery time, infection, rupture of the plantar fascia, and failure to improve the pain. Coblation (TOPAZ) surgery has recently been proposed as alternative surgical approaches for the treatment of recalcitrant plantar fasciitis.
