Open reduction and intramedullary stabilisation of subtrochanteric femur fractures: A retrospective study of 56 cases.

Subtrochanteric femur fractures commonly present with predictable displacement because of the deforming muscle forces acting upon the proximal femur. For this reason, successful closed reduction and femoral nailing can be a technically demanding procedure. Open reduction prior to nail placement has been advocated to improve and maintain anatomic fracture alignment. The purpose of this study was to evaluate the results of patients with closed subtrochanteric femur fractures treated with open reduction and a reamed antegrade statically locked intramedullary nail. An initial query of our database identified 154 patients who had sustained a subtrochanteric femur fracture over the defined study period. Ninety-six patients had adequate radiographic and clinical follow-up. Fifty-six (58%) patients were treated with open reduction and nail placement. There were no wound complications or infections and all patients went on to successful osseous union. There was no loss of reduction and a final coronal and sagittal plane deformity of <5 degrees in 55 of 56 (98%) patients. Open reduction of closed subtrochanteric femur fractures followed by intramedullary nailing leads to high union rates with rare complications.
