JOINT PROSTHESIS AND METHOD FOR PLACEMENT

摘要

A prosthesis (10) for replacement of a ball and socket joint in the human body. The prosthetic components comprise a plurality of separate parts (20a-j) which may be inserted through a hole in the femur of the patient and assembled and attached to the prepared acetabulum of the hip bone to form a cup-shaped first shell (16). A cup (106) is also passed through the hole in the femur and attached to the first shell to form the socket portion (12) of the joint. A shaft (114) having a first end with a ball (110) formed thereon is inserted in the hole through the femur so that the ball engages the cup for movement therein.
