Resumen (ES)
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.
