Salvage of Failed Trochanteric Fracture Fixation Using the Revitan Curved Cementless Modular Hip Arthroplasty

Abstract

Failed internal fixation of an intertrochanteric or subtrochanteric fracture often leads to persistent pain and diminished function. This study evaluated 16 patients treated with Revitan curved cementless modular stem (Zimmer GmbH, Winterthur, Switzerland). At a mean follow-up period of 60 months, all patients demonstrated clinically significant pain relief and return to ambulation after salvage total hip arthroplasty. Mean Harris Hip Score improved from 17.8 to 87.7 points postoperatively. Radiographic follow-up demonstrated stable stem and bony ingrowth in 16 patients without evidence of subsidence. Eight patients had slight awareness of lateral trochanteric pain with no compromise of activities, and 1 patient had nonunion of the greater trochanter. Revitan curved cementless modular stem represents a useful treatment option in salvage total hip arthroplasty of failed pertrochanteric fixation.
