ABSTRACT
Fluted tapered revision femoral stems have been used successfully in Europe. Modularity makes these implants more versatile, but outcomes of modular designs have not been reported. We report a retrospective review of 70 such stems with a mean follow-up of 47 months. Combined metaphyseal/diaphyseal bone loss was present preoperatively in 36 (51%) of 70 hips. Three hips (4.3%) were re-revised or in need of re-revision, and worst-case survival was 87%. The mean postoperative patient-assessed Oxford Hip Score was 21.1. Restoration of proximal bone was noted in 56%. Complications included mean subsidence of 9.9 mm, dislocation in 7 (10%) of 70 hips, and fracture or cortical perforation in 17 (24.2%) of 70. These results are equivalent to, or better than, reported results of other types of cementless revision femoral stems.
