title: Role and results of tapered fluted modular titanium stems in revision total hip arthroplasty.
abstract: Tapered, fluted, modular, titanium stems have   a long history in Europe and are increasing in popularity in North America.   We have reviewed the results at our institution looking at stem   survival and clinical outcomes. Radiological outcomes and quality   of life assessments have been performed and compared to cylindrical   non-modular cobalt chromium stems. Survival at five years was 94%.   This fell to 85% at ten years due to stem breakage with older designs.   Review of radiology showed maintenance or improvement of bone stock   in 87% of cases. Outcome scores were superior in tapered stems despite   worse pre-operative femoral deficiency. Tapered stems have proved   to be a useful alternative in revision total hip arthroplasty across   the spectrum of femoral bone deficiency.
