The plantar fascia is a band of thick connective tissue on the bottom of the foot which supports the arch. It extends from calcaneus to the metatarsal bones like a cable connecting the front and back portions of the foot. Abnormalities of the plantar fascia include plantar fasciitis (an inflammatory process), fibroma (a benign fibrous soft tisse mass) and tear ( possibly related to previous cortisone injection). The plantar fascia serves a major role in the biomechanics of the foot. In the setting of a plantar fascia tear, the arch loses support leading to collapse.
