Ball and socket trochanteric osteotomy

Globular trochanteric osteotomy for the surgical treatment of femoral condyle spondylolisthesis. Chronic spondylolisthesis of the femoral head can lead to three-dimensional deformity of the hip: hip varus, overextension and moderate or severe external rotation deformity, making deformity correction difficult. If the femoral condyle has been closed, the slippage will not be further aggravated, which means that the deformity of the femoral skull is slippery. For both types of patients, ball-shaped trochanteric osteotomy or two-dimensional trochanteric osteotomy can be used to correct the deformity. Treatment of diseases: femoral skull and tibial rickets Indication Ball-shaped trochanteric osteotomy is available for: 1. The femoral skull is a chronic slipper. 2. The femoral skull is slippery and deformed. Preoperative preparation The orthotopic and lateral radiographs of the proximal femur were recorded on the cardboard and the severity of the deformity was accurately measured. Through the method of paper cutting, it is expected that the broken end of the bone after osteotomy should be fixed. Surgical procedure Incision and exposure The lateral approach of the hip joint was used to fully reveal the range of 7.5 to 10 cm in the femoral trochanter and the proximal femoral shaft. 2. Osteotomy In the small trochanter plane, a guide needle is traversed through the femur. In the femoral trochanteric region and the proximal part of the femoral shaft, a bone knife is used to cut the mark at the osteotomy site, and the distal end of the osteotomy should be determined when fixed. Angle of rotation, buckling and abduction. In the small trochanter plane, the osteotomy line is convex to the far side (Fig. 3.2.2.4.1-4). Along the mark at the osteotomy, a bone drill is used to drill a hole in the cortical bone, and a bone knife is used to connect the bone hole so that the direction of the osteotome is directed to the proximal end. In this way, the distal end of the osteotomy can be convex and the proximal end is concave. 3. Fixed The distal end of the osteotomy was abducted, flexed, and internally rotated to an appropriate angle according to the angle determined before surgery. Secure with a bladed steel plate or a compression screw. 4. Suture the incision layer by layer.
