Objectives: Management of unstable intertrochanteric fractures is challenging, especially in patients with osteoporosis. Comminuted unstable intertrochanteric fractures require postoperative immobilization. Several recent reports have recommended hemiarthroplasty for treatment of unstable intertrochanteric fractures to avoid various immobilization-associated complications. The purpose of this study was to evaluate the functional and clinical outcomes of bipolar hemiarthroplasty for unstable intertrochanteric fractures in older persons.

Methods: Sixty patients aged over 75 years underwent hemiarthroplasty to treat unstable intertrochanteric fractures and were followed up over 12 months. All surgeries were performed by the same surgical team using the standard posterolateral approach. Wires, cables, and plates were used as required. Use of cemented protheses was considered when the lesser trochanter had been displaced. All patients were allowed full weight-bearing as tolerated. Clinical evaluation was based on Harris Hip Scores.

Results: The cohort comprised 16 men and 44 women (aged 75–96 years). According to the Jensen classification, 24 fractures were type III, 14 type IV, and 22 type V. Cement was used in 24 patients. At 12 months follow-up, Harris Hip Scores were excellent in 18%, good in 42%, fair in 25%, and poor in 15%. No radiological abnormalities were detected.

Conclusions: Primary bipolar hemiarthroplasty for treating unstable intertrochanteric fractures eliminates the need for prolonged immobilization and permits early ambulation. As reported by others, hip hemiarthroplasty is an effective treatment choice for unstable intertrochanteric femoral fracture in older patients.
