METATARSAL JOINT SHAPE FOR PROSTHETIC FOOT AND CONTROL MECHANISM AND SYSTEM FOR SAME

摘要

A prosthetic foot can include a plate-like foot member (102) extending along a longitudinal axis between an anterior end generally corresponding to a toe portion (112) of a foot to a posterior end, and a metatarsal hinge comprising an elongate groove (148) extending between medial (138) and lateral edges (139) of the foot member (102). The elongate groove (148) can intersect the longitudinal axis of the foot member, and can be positioned along the length of the foot member (102) at a location generally corresponding to a metatarsal region of the foot. The metatarsal hinge can also comprise a plurality of elongate apertures (348) that extend completely through the foot member (102), or a plurality of recessed channels (348') that extend only partially through the foot member (102), or a combination thereof.
