摘要
The modified method of Biplane Double-supported Screw Fixation (Modified BDSF) (Calcar buttressed screw fixation) of femoral neck fractures is disclosed. BDSF is applied using three standard bone screws laid in two vertical oblique planes in the femoral neck: the inferior (distal) screw is placed at an obtuse angle in the posterior oblique plane, and touched on the inferior (distal) and on the posterior cortices of the femoral neck; the middle screw and the proximal screw are laid in the anterior oblique plane and in parallel to each-other, with the middle screw touched on the distal femoral neck cortex. With BDSF of the three screws, two are weight-bearing and act as console beams: the distal screw and the middle screw, each of them having two supporting points in the distal fragment: medial (on the distal femoral neck cortex), and lateral (in the place of screw entry into the lateral femoral cortex).
