Key result
Cementless bipolar hemiarthroplasty is linked to ~74% fewer revisions and earlier mobilization vs proximal femoral nailing.
Why the study?
Unstable intertrochanteric femur fractures in geriatric patients carry high morbidity and mortality, prompting a comparison of clinical outcomes between cementless bipolar hemiarthroplasty via a transtrochanteric approach and proximal femoral nailing.
Does cementless bipolar hemiarthroplasty improve clinical outcomes compared to proximal femoral nailing in elderly patients with unstable intertrochanteric femur fractures?

BHA may enable earlier mobilization despite greater blood loss; Level 3 evidence leaves open practice change pending randomized confirmation.
Does cementless bipolar hemiarthroplasty improve clinical outcomes compared to proximal femoral nailing in elderly patients with unstable intertrochanteric femur fractures?
In elderly patients with unstable intertrochanteric fractures, cementless bipolar hemiarthroplasty allows earlier mobilization and fewer revisions than proximal femoral nailing, though at the cost of greater blood loss.
Polat et al. (2025) studied this question. Cementless bipolar hemiarthroplasty resulted in earlier mobilization (1 day vs. 3 days; p < 0.001) and fewer revisions (4.7% vs. 17.9%; p = 0.018) compared to proximal femoral nailing.
