It is estimated that roughly 10% of the population will suffer from heel pain at some point in their life. Plantar Fasciitis, also known as heel pain is the most common foot issue seen by clinicians. The heel pain comes from the plantar fascia- a thick band of tissue that runs from the heel bone, calcaneous, to the first bone of the toes, the proximal phalanx.
It has been discussed that the term fascia may be incorrect and the term aponeurosis best describes the structure. An aponeurosis is flat band of tissue that behaves more like a tendon. The plantar fascia supports the arch of the foot and consists of three bands of tissue: the lateral, medial, and central portion. The central band is what extends from the heel to the toes.
