Cemented calcar replacement hemiarthroplasty for unstable intertrochanteric fracture femur in elderly patients

Background
Unstable intertrochanteric fractures in elderly patients are associated with a high rate of complications and poses difficulty in fixation. Cemented calcar replacement hemiarthroplasty may be a suitable treatment in these patients. The aim of this study is to assess the clinical and functional results of the use of such a prosthesis in old patients with an unstable intertrochanteric fracture of the femur.
Patients and methods
Thirty patients were included in this prospective study, mean age 66 years. All the patients had unstable intertrochanteric fractures. Only patients with type III, IV, or type V fractures according to the Evans’ classification were included in the study. Functional and radiological results were assessed after a mean follow-up period of 22 months.
Results
At the end of the study, only 24 patients were available for evaluation. The mean follow-up period was 22 months (range, 18–36 months). At the last follow-up, the mean Harris hip score was 85 points. Radiologically, all stems were stable, without significant changes in alignment or progressive subsidence. No infection or thromboembolic complications were encountered.
Conclusion
Cemented bipolar hemiarthroplasty with calcar replacement is a good option for unstable intertrochanteric fractures in the elderly. It allows early weight bearing and rapid return to prefracture activity and does not have the difficulty and complications of internal fixation of this complex fracture.
