The Plantar Fascia is a broad, thick band of tissue that runs from under the heel to the front of the foot. Through overuse the fascia can become inflamed and painful at its attachment to the heel
bone or calcaneus. The condition is traditionally thought to be inflammation, however this is now believed to be incorrect due to the absence of inflammatory cells within the fascia. The cause of
pain is thought to be degeneration of the collagen fibres close to the attachment to the heel bone.
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position,
your abductor hallucis muscle-the muscle responsible for moving your big toe away from your footâs midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow
through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other
recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic
arthritis, Corticosteroid injections.
The symptoms of plantar fasciitis include pain in the bottom of your foot, especially at the front or centre of the heel bone, pain that is worse when first rising in the morning (called "first-step
pain"), when first standing up after any long period of sitting, or after increased levels of activity especially in non-supportive shoes. Seek medical advice about plantar fasciitis if you have heel
pain or pain in the bottom of your foot, especially when you get up in the morning, that does not respond to treatment or if there is redness or bruising in the heel.
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain
other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are
found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
Non Surgical Treatment
In general, plantar fasciitis is a self-limiting condition. Unfortunately, the time until resolution is often six to 18 months, which can lead to frustration for patients and physicians. Rest was
cited by 25 percent of patients with plantar fasciitis in one study as the treatment that worked best. Athletes, active adults and persons whose occupations require lots of walking may not be
compliant if instructed to stop all activity. Many sports medicine physicians have found that outlining a plan of ârelative restâ that substitutes alternative forms of activity for activities
that aggravate the symptoms will increase the chance of compliance with the treatment plan. It is equally important to correct the problems that place individuals at risk for plantar fasciitis, such
as increased amount of weight-bearing activity, increased intensity of activity, hard walking/running surfaces and worn shoes. Early recognition and treatment usually lead to a shorter course of
treatment as well as increased probability of success with conservative treatment measures.
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.
