The aim of this study was to describe the surgical technique of and indications for percutaneous pelvic osteotomy in patients with severe cerebral palsy. Forty non-ambulatory children and adolescents (47 hips) were consecutively treated with percutaneous pelvic osteotomy. The mean preoperative Reimers' migration percentage improved from 66.2% to 4.9% at the final follow-up. The mean preoperative acetabular angle (AA) improved from 32.4° to 13.2° at last follow-up. Percutaneous pelvic osteotomy is a less invasive surgical approach and appears to be a valid option with similar outcomes to standard techniques.This method results in less muscle stripping and blood loss and a shorter operating time.
