Routine use of mechanical thromboprophylaxis is recommended in patients undergoing hip fracture surgery.

Purpose. To compare patients with or without intra-operative fracture during cementless bipolar hemiarthroplasty. Methods. Records of 76 men and 202 women who underwent cementless bipolar hemiarthroplasty for femoral neck fractures were reviewed. Patients with and without intra-operative fractures and patients with different types of intra-operative fractures were compared. Results. Two men and 22 women aged 62 to 93 (mean, 80) years sustained intra-operative fractures at the lesser trochanter (n=18), the greater trochanter (n=5), and the subtrochanter (n=1). All 18 lesser trochanteric fractures and 4 of the greater trochanteric fractures were recognised intra-operatively and managed with cerclage wiring (n=21) or conversion to cemented hemiarthroplasty with cerclage wiring (n=1). The remaining 2 fractures were recognised postoperatively on radiographs and managed Intra-operative fractures in cementless bipolar hemiarthroplasty
