Short-stemmed uncemented femoral component for primary hip arthroplasty

Clin Orthop Relat Res. 1989 Dec:(249):169-75.

Abstract

A short-stemmed femoral implant differing from conventional design assumptions demonstrates that immediate three-point proximal femur fixation is possible without stem fixation. A double-wedged contour and neck shaft angle of 150 degrees help secure immediate stability and lessen an excessive varus moment. Results of 20 patients with at least one year of follow-up study are encouraging. Nineteen (95%) are classified as satisfactory with a Harris hip score of 44.5 before and 97.8 after surgery. One patient was revised for loosening; no patient has thigh pain. The gratifying early results justify further clinical investigation.
