We describe our experience with atypical cases of basicervical fracture of the femur. The fracture line lay between the anterior aspect of the subcapital portion and the posterior aspect of the neck base, running through the neck with a shearing fracture line as viewed in the coronal plane. We treated ten cases : seven by hemiarthroplasty and three by osteosynthesis. Bone union was obtained within six months, and there was no implant failure or complication. For diagnosis of this fracture, careful radiological assessment is important, and for effective treatment the special characteristics of this fracture should be considered. Cases of this type present difficulty with reduction and acquisition of stable fixation because of the cortical defect of the calcar or shortness of the anterior portion of the proximal fragment.
