Plantar fasciitis is an inflammation of the structures (of the plantar fascia) on the sole of the foot. The inflammation is caused by excess pressure on the structures on the sole of the foot. The plantar fascia becomes inflamed and tiny rips can occur where it attaches into the inside of the heel bone. It tends to be most painful first thing in the morning, or when standing up after sitting for a while. The area becomes inflamed and swollen, and it is the increase in fluid to the area that accumulates when weight is taken off the area, that then causes the pain on standing. Plantar Fasciitis usually starts gradually with pain on standing after rest. Pain is usually located under the heel or to the inside of the heel. Pain is usually at its worst on standing first thing in the morning. The pain will begin to ease once you get moving. Pain in the early stages tends to occur after activity rather than during activity. As plantar fasciitis continues the pain can become more constant and can then start to affect the way you walk.
Currently no single factor has been reliably identified as contributing to the development of plantar fasciitis. The two risk factors with the most support from current research. Decreased ankle dorsiflexion. Increased Body Mass Index (BMI) in non-athletic populations. These factors are related in that both lead to increased strain on the arch, both lead to increased compression on the heel. When dorsiflexion range of motion (ankle flexibility) is lacking, the body compensates by increasing movement of the arch. In this way, decreased ankle dorsiflexion influences pronation and places strain on the underside of the foot. Similarly, having a high BMI causes strain because it places a load on the foot that may be in excess of what the foot can support. As mentioned earlier, overpronation is thought to be a contributing factor, but studies on this have so far produced mixed results. The second way these factors relate to each other is in the way people stand. A lack of ankle flexibility and a high BMI can both cause increased pressure on the heel in standing. Keeping weight on the heels causes compression under the heel. But it also means the muscles and ligaments in the arch are not being used to balance your body weight. Lack of use, I suspect, is a greater danger than overuse. Looking beyond these potential contributors to heel pain though, there is one major factor that overshadows them all-the way footwear alters the normal function of the foot.
When plantar fasciitis occurs, the pain is typically sharp and usually unilateral (70% of cases).Heel pain worsens by bearing weight on the heel after long periods of rest. Individuals with plantar fasciitis often report their symptoms are most intense during their first steps after getting out of bed or after prolonged periods of sitting. Improvement of symptoms is usually seen with continued walking. Numbness, tingling, swelling, or radiating pain are rare but reported symptoms. If the plantar fascia continues to be overused in the setting of plantar fasciitis, the plantar fascia can rupture. Typical signs and symptoms of plantar fascia rupture include a clicking or snapping sound, significant local swelling, and acute pain in the sole of the foot.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
Teatment of plantar fasciitis can be a long and frustrating process for both the coach and athlete. If you do not have a firm grasp of the goals of this rehabilitation program your best advice will be to find a professional who routinely deals with athletic injuries. The “down time” for plantar fasciitis will be at least six weeks and up to six months of conservative care before drastic measures like surgery should be considered. The goal of this rehab program is to initially increase the passive flexion of the foot eventually leading to improvements in dynamic balance and flexibility of the foot and ankle, followed by a full return to function.
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.
