Lengthening osteotomy of the greater trochanter of the hip with capping

Hip-capped femoral greater trochanter extended osteotomy for the treatment of hip joint deformity. Curing disease: Indication Hip-capped femoral greater trochanter extended osteotomy for paralytic hip dislocation with short limb deformity and excessive anteversion. Contraindications Accompanied by hip contractures. Surgical procedure 1. Incision: Take a modified Smith-Petersen incision. The hip joint was exposed, and a 6 cm x 5 cm x 1 cm tibia block was cut on the opposite side. 2. Under the rim of the iliac crest, the switch is cut in a curved shape. When the hip joint is rotated, the joint is unstable, and the femoral head has a tendency to slip outside. The femur is cut obliquely at the lower edge of the trochanter. Cut 2cm×6cm long bones from the ipsilateral humerus into two segments; place the femoral head in the acetabulum to restore the normal neck angle, straighten the distal limb axis, and extend the two bone ends with a separator. After the bone graft is embedded in the bone end, it can be extended by the bone plate. 3. Use a curved osteotomy knife to cut an arcuate bone groove 0.5cm above the edge of the acetabulum. The length is about 5cm, the width is 0.8~0.9cm, the depth is 2~2.5cm, and the prepared curved humerus piece is down. It is placed in the bone groove at 45° outside and is tightly packed with a squeezer to deepen the stability of the acetabulum.
