Article Description

Based on radiographs this investigation makes effort to differentiate several possible osseous reactions (resorption, apposition, remodelling) at the calcar femoris following total hip replacement. A series of patients with Charnley-Müller and McKee-Huggler type total hip replacement is compared to a series of patients with the Lindenhof-type AlO-ceramic hip replacement. Three different types of calcar femoris resorption as well as two types of so-called calcar adaptation could be distinguished throughout this study. Type I calcar resorption is related to post operative disturbance of vascularisation of this area, type II calcar resorption is mainly due to foreign body reaction against wear-particles and PMMA fragments, type III calcar resorption is mainly connected to stem loosening. In series 153 p.c. of all cases had calcar resorption (thereoff: 70 p.c. type I; 18 p.c. type II; 12 p.c. type III), in series 11 only 10 p.c. of all cases showed calcar resorption (4 p.c. type I; 6 p.c. type III). In series II two adaptive calcar reactions (1. atrophy of calcar femoris, 2. remodelling of calcar femoris without deficit in contour) could be distinguished. The reasons for these adaptive mainly biomechanical calcar reactions are discussed in detail reflecting the fact that in series II Charnley- and Weber-type stems were inplanted both having only a small collar. Based on this discussion consequences for a new stem design are formulated, the new design is presented. © 1978 J. F. Bergmann Verlag.
