Anatomy
Fascia consisting of thick connective tissue, of which most are longitudinally oriented collagen fibers. Attaches posteriorly to the tuberosity of the calcaneus, and anteriorly to the metatarsals. The fascia has three components: medial, central (which is the largest), and lateral.
Functions
Supports plantar aspect of the foot, and helps keep the arch of the foot by acting as a tie-rod.
Contributes to the ‘Windlass Mechanism’ during gait.
Clinical
Overuse of the plantar fascia can cause plantar fasciitis – a painful inflammation of the fascia.
