The purpose of this study is to determine the effect on hip rotation of hamstring lengthening as measured by preoperative and postoperative motion analysis. Thirty-eight patients/76 hips in children with cerebral palsy spastic diplegia were retrospectively reviewed using presurgical and postsurgical gait analysis. Physical examination and gait analysis showed an increase in knee extension and decreased popliteal angles postoperatively. Kinematic analysis showed an increase in knee extension and decreased hip internal rotation throughout the gait cycle postoperatively as well. No difference was seen between those with internal and external rotation pattern at the hip preoperatively. As a group, the patients did not improve enough to change from internal to external rotation at the hip, suggesting that children with cerebral palsy spastic diplegia with significant internal rotation gait should have other surgical options besides hamstring lengthening when internal rotation gait of the hip is to be treated. © 2007 Lippincott Williams & Wilkins, Inc.
