SURGICALLY IMPLANTABLE PROSTHETIC JOINT

摘要

A surgically implantable hinge joint for replacing a damaged or diseased natural hinge joint in the skeletal structure of humans and other animals and composed of relatively rotatable ball- and socket-members each having elongate shank portions for implantation in the proximal end portions of the bones which are severed from the removed natural joint, and which provides for at least limited axial rotation of one of the joint members relative to the other together with relative hinging or pivotal swinging movement of such members in a given plane.
