Plantar fasciitis is a painful inflammatory process of the plantar fascia, a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the five toes. Pain in the arch or heel often indicates inflammation of the long band of tissue under the foot (the plantar fascia). It can cause sharp pain and discomfort in either the mid arch region or at the inside heel, and less commonly the outside heel. It frequently causes pain upon rising from rest (especially first thing in the morning) and can progress to agony by the end of the day. Although plantar fasciitis is the most common cause of this pain, it must be skilfully differentially diagnosed from other conditions via a thorough history taking and physical examination.
Identified risk factors for plantar fasciitis include excessive running, standing on hard surfaces for prolonged periods of time, high arches of the feet, the presence of a leg length inequality, and flat feet. The tendency of flat feet to excessively roll inward during walking or running makes them more susceptible to plantar fasciitis. Obesity is seen in 70% of individuals who present with plantar fasciitis and is an independent risk factor. Studies have suggested a strong association exists between an increased body mass index and the development of plantar fasciitis. Achilles tendon tightness and inappropriate footwear have also been identified as significant risk factors.
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.
Plantar fasciosis is confirmed if firm thumb pressure applied to the calcaneus when the foot is dorsiflexed elicits pain. Fascial pain along the plantar medial border of the fascia may also be present. If findings are equivocal, demonstration of a heel spur on x-ray may support the diagnosis; however, absence does not rule out the diagnosis, and visible spurs are not generally the cause of symptoms. Also, infrequently, calcaneal spurs appear ill defined on x-ray, exhibiting fluffy new bone formation, suggesting spondyloarthropathy (eg, ankylosing spondylitis, reactive arthritis. If an acute fascial tear is suspected, MRI is done.
Non Surgical Treatment
Treatment of heel pain caused by plantar fasciitis begins with simple steps. There are a number of options for treatment of plantar fasciitis, and almost always some focused effort with nonsurgical treatments can provide excellent relief. In rare circumstances, simple steps are not adequate at providing relief, and more invasive treatments may be recommended. Typically, patients progress from simple steps, and gradually more invasive treatments, and only rarely is surgery required.
If you consider surgery, your original diagnosis should be confirmed by the surgeon first. In addition, supporting diagnostic evidence (such as nerve-conduction studies) should be gathered to rule out nerve entrapment, particularly of the first branch of the lateral plantar nerve and the medial plantar nerve. Blood tests should consist of an erythrocyte sedimentation rate (ESR), rheumatoid factor, human leukocyte antigen B27 (HLA-B27), and uric acid. It’s important to understand that surgical treatment of bone spurs rarely improves plantar fasciitis pain. And surgery for plantar fasciitis can cause secondary complications-a troubling condition known as lateral column syndrome.
Warm up properly. This means not only stretching prior to a given athletic event, but a gradual rather than sudden increase in volume and intensity over the course of the training season. A frequent cause of plantar fasciitis is a sudden increase of activity without suitable preparation. Avoid activities that cause pain. Running on steep terrain, excessively hard or soft ground, etc can cause unnatural biomechanical strain to the foot, resulting in pain. This is generally a sign of stress leading to injury and should be curtailed or discontinued. Shoes, arch support. Athletic demands placed on the feet, particularly during running events, are extreme. Injury results when supportive structures in the foot have been taxed beyond their recovery capacity. Full support of the feet in well-fitting footwear reduces the likelihood of injury. Rest and rehabilitation. Probably the most important curative therapy for cases of plantar fasciitis is thorough rest. The injured athlete must be prepared to wait out the necessary healing phase, avoiding temptation to return prematurely to athletic activity. Strengthening exercises. Below are two simple strength exercises to help condition the muscles, tendons and joints around the foot and ankle. Plantar Rolling, Place a small tin can or tennis ball under the arch of the affected foot. Slowly move the foot back and forth allowing the tin can or tennis ball to roll around under the arch. This activity will help to stretch, strengthen and massage the affected area. Toe Walking, Stand upright in bare feet and rise up onto the toes and front of the foot. Balance in this position and walk forward in slow, small steps. Maintain an upright, balanced posture, staying as high as possible with each step. Complete three sets of the exercise, with a short break in between sets, for a total of 20 meters.
