Primary bipolar replacement arthroplasty versus internal fixation in the management of unstable intertrochanteric fractures in the elderly

Background Management of unstable intertrochanteric femur fracture in the elderly has been always a matter of debate. There has been always a dilemma between osteosynthesis and prosthesis.

Methods We retrospectively evaluated, 108 osteoporotic elderly patients with unstable intertrochanteric for internal fixation versus primary bipolar replacement arthroplasty in a span of 4 years.

Results Bipolar replacement arthroplasty gives better outcome as compared to internal fixation with sliding hip screw.

Conclusions It was found that cemented bipolar arthroplasty is the choice in freely mobile elderly osteoporotic comminuted displaced intertrochanteric fracture, though is a surgically demanding technique, it spares the postoperative complication of non-weight bearing after internal fixation of these fracture. The internal fixation is also compounded by osteoporosis, medical illness, difficulty to achieve and maintain reduction of comminuted and widely displaced unstable fractures, which restricts the mobilization and weight bearing and further increase the risk of morbidity and mortality in elderly in comparison to cemented bipolar replacement arthroplasty which allows early mobilization and weight bearing.
