Document Summary
Attached to spring ligament (plantar calcaneonavicular ligament) for support. Medial longitudinal arch allows us to divide into different foot types. Associated with excessive pronation: pes cavus. Gives protection to soft tissue and increases the foots mobility. Also metatarsal arch from 1st to 5th metatarsal. Central band that originates form medial tubercle on plantar surface of calcaneus and that travels towards the toes as a solid band of tissue dividing just prior to the mt heads into 5 slips. When the toes are extended, the plantar fascia is functionally shortened as it wraps around each. Mt head in this way, the plantar fascia functions like a muscle (i. e. it has a dynamic function) It is responsible for transferring the weight from the medial to the lateral side of the foot during the gait cycle as well as arch support/dynamic shock absorption. At initial contact and early loading there is double contact (both feet on ground)
