It is the purpose of this paper to follow-up the results on our cases of 16 neck and 18 trochanteric fractures of the femur, which had been treated by the cross-screw fixation technique with the Y-screw during past seven years. In the neck fracture of the femur, it is hopeful that the low angle screw is inserted as possible as obliquely through the Adam's bow and the cross angle of the two screws is made up the sixty degrees on the anteroposterior view.
The results was influenced by the comminution at the postero-inferior aspect and the acceptable reduction of the medial cortical buttress of the femoral neck. The stability may be restored by reduction in the valgus position rather than the varus position.
On the other hand, in the trochanteric fracture of the femur, the cross-screw fixation technique had good results in the stable type but had no indication for the unstable type of this fracture. We consider that union is almost certain to occur, when by some means the stability and its maintenance of the calcar femorale is obtained.
