Osteotomy refers to shaving off bone to reshape it. In the cases of pelvic osteotomy, the pelvic side of the socket is repaired. This should help to provide some stability to the joint. If the upper thigh bone is reshaped, this is called a femoral osteotomy. In some cases, pins and plates are utilized.
The direct translation of osteotomy is “cutting of the bone.” During most surgeries involving the hips, patients undergo either general anesthesia or epidural anesthesia. An x-ray machine is used to assist in the pelvic bone alteration around the hip socket in a pelvic osteotomy. Four separate bone cuts are used to completely free the acetabulum from the pelvis.
