We describe comparative examination of operation results of Hansson pin® (H group) and Twins® (T group) for femoral neck fracture. For the displaced type, Garden alignment index (GAI) decreased in the H group, and the bone union rate fell by correction loss after the operation. In the T group could maintain an angular stability and GAI was little change after the operation, and the bone union rate was good compared with the H group. We could think the implanting choice from which an angular stability is obtained in the displaced type.
