Abstract

A universal modular frame for use as a component in an above-knee endoskeletal prosthesis comprises a one-piece rigid outer frame of closed configuration having an upper sleeve extending between lateral and medial sides of the frame and adapted for connection to a linkage and socket for an above knee amputation, rigid lateral and medial side arms rigidly affixed to and extending downwardly from the sleeve, the lateral and medial side arms having recessed lightening recesses therein for reducing the weight of the frame, and a lower base extending between and rigidly affixed to bottom portions of the lateral and medial side arms. The outer frame forms the perimeter of an open central region for mounting a knee motion and gait control unit. The lower base has a flat bottom face and a pattern of spaced apart holes extending through the lower base for use in receiving corresponding fastening means for rigidly but releasably affixing an upper connecting portion of a lower leg pylon to the bottom of the outer frame. The lower means of attachment on the base of the frame provides a means for mounting to the frame a variety of lower leg pylons depending upon the patient' s needs.
