title: Osteotomy does not improve early outcome after slipped capital femoral epiphysis.
abstract: We performed a retrospective, nonrandomized cohort study of unilateral, chronic, severe, stable slipped capital femoral epiphysis comparing five girls and five boys who underwent in-situ screw fixation alone with five girls and five boys who underwent in-situ screw fixation combined with staged flexion intertrochanteric femoral osteotomy to restore proximal femoral alignment. Functional outcome was measured by the Harris hip score, with 20% selected as a goal for improvement in functional outcome after corrective osteotomy. While flexion intertrochanteric femoral osteotomy improved hip range of motion, we found no significant difference in functional outcome between the two groups at early follow-up. This is a level 3 evidence study.
