| 摘要 |
A joint prosthesis including two articular parts is characterised in that at least one of said articular parts comprises at least one first stage component and at least one second stage component for implantation at a first stage operation and a second stage operation respectively, said first stage component or components consisting of a surgically insertable structure of appropriate shape and strength to receive eventually at least one second stage component thus creating a composite with sufficient strength and fixation to the bones remaining adjacent the joint replaced by the prosthesis to take the place of the natural elements of the joint being replaced, the first stage component or components including connection means designed to cooperate with connection means of a second stage component, the second stage component forming or supporting at least in part, a bearing surface of the joint prosthesis, and designed so as to be disconnectable as an initial stage of a revision procedure. Hip joint prostheses and methods of total hip arthroplasty are specifically disclosed. |
