Operation

A conservative procedure requires one and a half hour of surgery and five nights of hospitalization. The peri-acetabular osteotomy is performed according to a precise plan to correct the bone deformity. The goal is to restore a more physiological shape to the hip joint in order to delay its degradation. The peri-acetabular osteotomy does not change the shape of the pelvis and allows future pregnancies.

Technique

The peri-acetabular osteotomy is performed under general anesthesia. A scar straddling the iliac crest and the upper thigh is made. Four lines of osteotomy are performed, preserving the posterior column of the iliac bone. These four osteotomies “around the acetabulum” allow the acetabulum to be detached from the iliac bone and reoriented into a suitable position. The new position of the acetabulum is checked by imaging with an image intensifier. The peri-acetabular osteotomy is usually fixed with 2 screws.
