Page 6: Operative Technique
Operative Technique Step 1 - Patient Positioning Correct positioning of the patient on the fracture table is essential for avoiding problems and complications during surgery (Fig. 1). Place the patient in supine position on the fracture table. Healthy side: Position the leg on the healthy side with the hip in flexion and slight abduction so that the C-arm can be adjusted intra-operatively for... -
Page 7: Reduction
Operative Technique Step 2 - Reduction Apply the surgical boot to the foot. Mild traction is applied for the sole purpose of maintaining the leg in the horizontal plane. Additional support under the thigh may be necessary. Rotate the foot internally by 30-60° and fix in position. -
Page 8: Optional Stabilization Guide Wire Insertion
Operative Technique Step 3 – Stabilization Guide Wire Insertion When treating unstable (acute) slips a Guide Wire may be used. Using biplanar floroscopy, it is inserted percutaneously in the trochanteric region into the femoral neck and head for intraoperative stabilization. (Fig. -
Page 9: Determining The Incision And Insertion Points
Operative Technique Step 4 – Determining the Incision Point and Implant Position Slipping of the femoral head occurs in a true posterior direction. The Hansson Pin must be positioned in the central part of the femoral head. To achieve this, the pin must be inserted anterior-laterally in the greater trochanter and then directed posteriorly (Fig. -
Page 10: Skin Incision And Guide Wire Insertion
Operative Technique Step 5 – Skin Incision and Guide Wire Insertion Make a 20mm incision at the site where the two lines on the thigh intersect. The insertion point on the anterior-lateral face of the proximal femur is identified at the level of the lesser trochanter (Fig. -
Page 11: Drilling And Measurement
Operative Technique Step 6 – Drilling and Measurement Insert the Cannulated Drill over the Drill Sleeve and the Guide Wire. The Drill Sleeve is pressed against the lateral cortex of the femur and the drill is advanced towards the centre of the femoral head (Fig. -
Page 12: Instrument-To-Pin Assembly
Operative Technique Step 7 – Instrument-to-Pin Assembly Verify that the inner pin is completely withdrawn in the window of the outer body and in correct position (Fig. 13). Pass the Inner Introducer through the Outer Introducer and screw it into the Hansson Pin (Fig. -
