Proximal femoral nailing is superior to hemiarthroplasty in AO/OTA A2 and A3 intertrochanteric femur fractures in the elderly: a systematic literature review and meta-analysis

Introduction Unstable intertrochanteric femoral fractures in the elderly require either fixation or joint sacrificing surgery; proximal femoral nail (PFN) and bipolar hemiarthroplasties (BPH) are the most common interventions. PFN is considered to be the ideal construct for these fractures; however, the usage of hemiarthroplasties to facilitate earlier mobilization has been on a rise. Currently there is no consensus on the superiority of one of these two techniques over the other and the present review was done to determine this.
