Mechanical Behaviors of the Foot After Individual Releases of Plantar Fascia and Ligaments During the Balanced Standing

摘要

To quantify mechanical effects of plantar fascia and ligaments on the arch structure,a 3D finite element model of the foot was created to simulate the balanced standing posture. Four cases after individual releases of plantar fascia,spring ligament,long and short plantar ligaments were simulated respectively to compare their consequences to the predictions of the intact structure. It was founded that the foot arch didn't collapse obviously after any individual release of these structures. As plantar fascia was released,tensions of plantar ligaments were largely increased. Long and short plantar ligaments performed mutual compensation functions.
