[Cementless Spotorno stem. Long term results].
Spotorno stem is a tapered straight cementless stem; Spotorno stem achieved initial stability by wedging a proximal fluted, straight stem into a retained bed of femoral trabecular and cortical bone, rectangular cross section provides excellent rotational stability distally. The titanium-aluminum-niobium alloy enables the fast ongrowth of newly formed osseous tissue to act as secondary stabilization This retrospective study reviews 26 Spotorno stems, the mean follow-up was 134 months. Clinical results were graded excellent and good in 93 per cent of hips. At follow-up, none patient presented radiological evidence of aseptic stem loosening and 100 per cent of stems showed stable fixation.
