Femoral Revision With a Fluted, Tapered, Modular Stem : Seventy Patients Followed for a Mean of 3.9 Years

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.
