We used a temporary THA-like spacer comprising the removed femoral long stem, which was autoclaved and then reimplanted, and applied a new polyethylene acetabular liner (Fig. 2a). During the procedure, the acetabular and femoral components of the temporary THA-like spacer were removed easily (Fig. 2b).
