MANAGEMENT OF FAILED INTERNAL FIXATION OF TROCHANTERIC HIP FRACTURES USING CEMENTLESS MODULAR HIP ARTHROPLASTY



Abstract

Introduction: Failure of internal fixation of intertrochanteric fractures may be associated with delayed union or malunion resulting in persistent pain and diminished function. The purpose of this study is to evaluate results of the use of a tapered, fluted, modular, distally fixing cementless stem in the management of failed treatment of intertrochanteric hip fractures in elderly patients.

Methods: 837 patients had internal fixation of intertrochanteric fractures over a seven year period (2000–2007) at our institution. Of these, 15 patients with mean age of 80.6 years (69.8–92.3), underwent hip arthroplasty for failure of internal fixation. Clinical and radiographic records of these patients were evaluated.

Results: At an average follow up of 2.86 (2–4.5) years, all patients showed marked functional improvement with change in mean Harris hip score from 35.90 to 83.01 (P < 0.01). Fourteen stems had stable bony ingrowth and one stem was loose and subsided by 5 mm. Three patients used a walker for ambulation, ten patients used a cane and two could ambulate without aids.

Conclusion: Use of a tapered fluted modular cementless stem allows stable distal fixation in a reproducible fashion with good functional outcome in this challenging cohort of patients. All patients were ambulatory, however majority used walking aids.
