PCT No. PCT/EP85/00251 Sec. 371 Date Jan. 8, 1987 Sec. 102(e) Date Jan. 8, 1987 PCT Filed May 23, 1985 PCT Pub. No. WO86/06954 PCT Pub. Date Dec. 4, 1986.A self-locking stemmed component (1) for a joint endoprosthesis consists of two lobes (4,5) of which one (4) is designed for transfer of compression loads and the other (5) for transfer of tension loads. Both lobes (4,5) are interconnected by a number of connecting structures (6), preferably in the form of struts, which are responsive to a bending moment to produce an increase of the stem thickness upon loading of the stemmed component (1), thereby pressing the lobes (4,5) against the inner cortex of the medullary canal (23) of a tubular bone (10). |
