Medium-term patient-reported outcomes after total hip replacement for displaced hip fractures.

Abstract

The aim of the present study was to define the medium-term outcomes following total hip replacement (THR) for hip fracture. We prospectively followed up 92 patients who underwent THR for a displaced hip fracture over a 3-year period between 2007 and 2010. These patients were followed up at 5years using the Oxford Hip Score, Short-Form 12 (SF-12) questionnaire and satisfaction questionnaire. These outcomes were compared to the short-term outcomes previously reported at 2years to determine any significant differences. Mean follow-up was at 5.4years with a mean age at follow-up of 76.5years. Seventy-four patients (80%) responded. Patients reported excellent functional outcomes and satisfaction (mean Oxford Hip Score 40.3; SF-12 Physical Health Composite Score 44.0; SF-12 Mental Health Composite Score 46.2; mean satisfaction 90%). The rates of dislocation (2%), deep infection (2%) and revision (3%) were comparable to those quoted for elective THR. When compared with 2-year follow-up, there were no statistically significant adverse changes in outcome parameters. Medium-term outcomes for THR after hip fracture in fit older patients are excellent, and these results demonstrate that the early proven benefits of this surgery are sustained into the midterm.
