Outcome of primary cemented bipolar hemiarthroplasty in older patients with unstable hip fracture: A prospective study

Objective: Internal fixation as a classical method of treatment for unstable intertrochanteric fractures in older patients has significant complications and failure rate. This raises the need for a method that overcomes these difficulties and gives a better outcome. This study aims to evaluate the outcome of the use of primary cemented bipolar hemiarthroplasty in older patients with unstable intertrochanteric fracture both clinically and functionally. Methods: A prospective case series study conducted from January 2014 to February 2016 including 60 patients (>65-year-old) who were treated by primary cemented bipolar hemiarthroplasty for unstable intertrochanteric fractures (Kyle 3 and 4). Main outcome measurements were clinical and mechanical complications, mortality rate, and functional outcome. Results: Early mobilization was good, that 93.3% of patients started partial weight-bearing on the 1st postoperative day. At the final follow-up (mean 13.66 ± 5.9 months), the general and mechanical complications were few; 1-year mortality rate was 16.7%; the mean Harris Hip score was 91.14 ± 5.7. Conclusions: Primary cemented bipolar hemiarthroplasty offers early, pain-free mobility with minimal complications and good functional outcome in older patients with unstable intertrochanteric fracture.
