The role of modularity in primary total hip arthroplasty.
A combined series of 795 primary SROM (DePuy, Warsaw, Ind) stems have been reviewed. The mean follow-up is 11 years; 2 (0.25%) were revised for aseptic stem loosening. Two (0.25%) cases of osteolysis distal to the sleeve occurred, 1 of which was revised. The low incidence of distal osteolysis and aseptic loosening justifies the continued use of this stem in primary total hip arthroplasties.
