摘要
A femoral prosthesis family with progressive lateralisation consists of at least two sub-familes with a constant cervico-diaphysis angle (alpha) in each sub-family but which varies from one sub-family to another. The angle reduces from the smaller sizes to the larger ones by 1.5 plus/minus 0.5 degrees, and in three sub-families, for instance, the angles are 135, 133.5 and 132 degrees, plus or minus 0.5 degrees in each case. The neck of each prosthesis is tipped by a Morse cone (4) with an angle of taper of 6 degrees plus/minus 10 min.
