Predictors of Intraoperative Fractures during Hemiarthroplasty for the Treatment of Fragility Hip Fractures

Hemiarthroplasty (HA) of the hip for fragility hip fractures can be inserted with cement or secured in the proximal femur with an uncemented press fit design.][3] Intraoperative fracture (IOF) is a known complication associated with treatment using a HA for hip fractures.The ensuing problems of IOF include poor functional outcomes, increased surgical time, revision rates, morbidity and mortality. 4)Therefore, identifying factors that lead to IOF in HA is vital to help prevent its occurrence.[7] Patients with intracapsular neck of femur fractures are generally frail with lower bone mineral density compared to patients in the elective population undergoing THR. 8,9)Measuring radiological parameters of the proximal femur has helped predict osteoporosis and bone mineral density. 10)Specific radiological parameters have also been shown to help predict IOF in patients receiving HA
