【求助】DHS surgical technique

Reduce fracture
If possible reduce the fracture while closed under the image intensifier. If an operating table without extension is used, reduce the fracture by flexion, lengthwise traction, abduction and internal rotation. Fix the fracture temporarily with Kirschner wires. Position the Kirschner wires so that they do not hamper insertion of the DHS/DCS screw and DHS plate.
Access
The proximal femur is approached laterally. Make a15–20 cm straight incision starting two finger widths proximal to the greater trochanter. Split the iliotibial tract lengthwise. Detach the M. vastus lateralis dorsally from the intermuscular membrane, retract ventrally and, if necessary, make a slight notch in the muscle in the region of the innominate tubercle. Expose the proximal femoral shaft without retracting the periosteum
Determine antetorsion
To determine the antetorsion of the femoral neck using the DHS Angled Guide and the DHS/DCS T-Handle, place a Kirschner wire ventrally over the femoral neck and tap the tip slightly into the femoral head. [标签:content1][标签:content2]
