Outcome after Schanz osteotomy in the treatment of chronic hip dislocation in children with cerebral palsy was evaluated. Medical charts and questionnaires were used to assess pain, functional outcome and satisfaction. A total of 24 children, with a mean age of 13.8 years (± 8.9), were included in the study, out of which 11 were classified with Gross Motor Function Classification System (GMFCS) level IV and 13 with GMFCS level V. Current pain was comparable to patients without chronic hip dislocation, and satisfaction was intermediate. Functional outcome improved in several domains. Longer postoperative time was associated with improved pain and satisfaction. The Schanz osteotomy allowed improvement in pain levels; however, it did not completely meet caregiver's expectation and has high reoperation rates.
