Primary fit of the lord cementless total hip: A geometric study in cadavers

Abstract

Two Lord prostheses, bilaterally implanted in cadavers, were sectioned. the contact areas between bone and prosthesis were studied and measured using a specially developed reproducible method. Primary fixation of the femoral components appeared to be based principally on wedging of the prosthetic stem in the femoral shaft with a rather small contact surface. In both acetabuli the screw threads of the rings were only marginally in contact with the acetabular bone. © 1988 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
