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.
Far and away the most common cause of plantar fasciitis in an athlete is faulty biomechanics of the foot or leg. Faulty biomechanics causes the foot to sustain increased or prolonged stresses over
and above those of routine ground contacts. Throughout the phase of ground contact, the foot assumes several mechanical positions to dissipate shock while at the same time placing the foot in the
best position to deliver ground forces. With heel landing the foot is supinated (ankle rolled out). At mid-stance the foot is pronated (ankle rolled in). The foot is supinated again with toe-off. The
supination of the foot at heel strike and toe-off makes the foot a rigid lever. At heel strike the shock of ground contact is transferred to the powerful quads. During toe-off forward motion is
created by contraction of the gastroc complex plantar flexing the rigid lever of the foot pushing the body forward.
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.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a personâs presenting history, risk factors, and clinical examination. Tenderness to palpation along the
inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles
tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis.
However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or
heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to
assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is
consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in
up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of
the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
Anti-inflammatory medications can help decrease the inflammation in the arch and heel of your foot. These medications include Advil, Mtrin, Ibuprofen, and Aleve. Use the medication as directed on the
package. If you tolerate it well, take it daily for two weeks then discontinue for one week. If symptoms worsen or return, resume for two weeks, then stop. You should eat when taking these
medications, as they can be hard on your stomach. Ach Support. Over the counter inserts provide added arch support and soft cushion. Based on the individual needs of your foot, you may require custom
inserts. Achilles Tendon Stretch. Pace a shoe insert under your affected foot. Place your affected leg behind your unaffected leg with the toes of your back foot pointed towards the heel of your
other foot. Lean into the wall. Bend your front knee while keeping your back leg straight with your heel firmly on the ground. Hold the stretch for a count of 10. A set is 10 repetitions. Perform the
stretch at least three times a day.
When more-conservative measures aren't working, your doctor might recommend steroid shots. Injecting a type of steroid medication into the tender area can provide temporary pain relief. Multiple
injections aren't recommended because they can weaken your plantar fascia and possibly cause it to rupture, as well as shrink the fat pad covering your heel bone. Extracorporeal shock wave therapy.
In this procedure, sound waves are directed at the area of heel pain to stimulate healing. It's usually used for chronic plantar fasciitis that hasn't responded to more-conservative treatments. This
procedure may cause bruises, swelling, pain, numbness or tingling and has not been shown to be consistently effective. Surgery. Few people need surgery to detach the plantar fascia from the heel
bone. It's generally an option only when the pain is severe and all else fails. Side effects include a weakening of the arch in your foot.
