Artificial limb joint - has pivoting portion half and support pivoting on stem fixed in bone

摘要

the joint comprises a stem anchored in one bone and equipped with one half of the pivoting portion, while a second half is attached to a second bone. A support is joined to the stem and bears against a supporting surface on the first bone. The first half of the pivoting portion (113) and the support (107) are parts of a component coupled to the stem (73) by a pivot pin, and they can be detachable from the latter. There can be a conical socket fitting over a cone on the stem and pressed against it by a screw engaging in the latter. The pivot joint can be of the hinged, ball-and-socket, gimbal or knife-edge type.
