Closeness of fit of uncemented stems improves the strain distribution in the femur.

Abstract

Differences in the cross-sectional shapes of intramedullary stems are expected to affect the strains in the femur, a close proximal fit being proposed as particularly advantageous. We compared uncemented femoral stems of different designs, as well as a cemented stem, using the intact femur as a control. The collarless stems were custom-made, standard… (More)
