Abstract
A spacer to be used with femoral hip prostheses. The spacer is placed under a existing collar of a femoral hip prosthesis and cemented or tied in place or both. The spacer comprises a U-shaped segment adapted to fit under a medial collar and partially enclose part of a proximal portion of the stem of a hip prosthesis. Spacer plugs are provided to offset the spacer slightly and provide a space which is filled with bone cement (PMMA), securely attaching the spacer to the prosthesis. A distal ledge which lies adjacent the proximal body of the prosthesis keeps the cement enclosed between the stem and the spacer. An area of porous coating is provided distally. A peripheral groove is also provided.
