Shaft for a hip joint prosthesis conically extending from the distal part

Abstract

Abstract 1. A shank widening conically from the distal end, for a hip joint prosthesis and formed with longitudinal ribs at least in the proximal region of its surface parts which, when fitted, extend substantially in the anterior/posterior direction, the ribs extending substantially in the direction of the longitudinal axis of the shank and the height of the ribs being not more than a quarter of the maximum thickness of the shank measured in the anterior/posterior direction between the rib apices, and the distance between two adjacent rib apices being at least equal to the rib height, characterized in that the longitudinal rib structure is formed in the proximal region with transverse grooves (10) at various non-horizontal angles (alpha) to the vertical longitudinal axis (3) of the shank (1).
