FEMORAL HEAD ADAPTOR FOR INTEROPERATIVE ASSEMBLY

摘要

An adaptor (40) is interposed between a socket (32) in a ceramic femoral head component (30) and a post (18) on a femoral stem component (12) in the femoral stem of a prosthetic hip joint to enable the use of a taper within the socket which is steeper than the taper on the post so as to reduce hoop stresses in the ceramic femoral head component while at the same time accomplishing securement of the ceramic femoral head component upon the post of the existing femoral stem component (12).
