title: Total hip replacement fifteen years after pelvic support osteotomy (PSO): a case report and review of the literature.
abstract: Treatment of chronic hip instability in children and young adults is challenging. Proximal femoral osteotomy had been suggested to provide pelvic stability and improved abductor function. Total hip replacement after pelvic support osteotomy can be challenging due to altered anatomy due to angulation of the proximal femur in both frontal and sagittal planes. This is a 29-year-old woman who had total hip replacement after pelvic support osteotomy. The patient had pelvic support at the age of 14 years. Pelvic support osteotomy delayed the need for total hip replacement for 15 years. Preoperative planning for total hip replacement with model was used for proper understanding of the anatomy of the proximal femur. Revision of femoral component was necessary due to penetration of the proximal femur. In conclusion, total hip replacement after pelvic support osteotomy is a technically demanding procedure, and careful attention to surgical details is necessary for successful outcome.
