摘要 |
An artificial ankle joint (FIG. 1) is of the kind which connects a shin member to a foot, by means of a ball and socket joint. The socket has adjacent main and subsidiary socket portions. The main socket portion has a first part, which engages the elastic covering of the ball, and a second part which extends down from the first part and receives within it the subsidiary socket portion. A circlip locks the parts together. The main socket portion includes an integral skirt which engages an annular elastic buffer which is mounted around the ball shank.
