Single Event Multilevel Surgery in Bilateral Spastic Cerebral Palsy: A Multi-centre, Long-term, Follow-up Study

Project Details

Single Event Multilevel Surgery (SEMLS) is considered the standard of care for orthopaedic surgical intervention in children with bilateral spastic cerebral palsy (BSCP). The efficacy of SEMLS is supported by one randomized clinical trial and many cohort studies. However, the majority of studies have limited numbers and short term follow up. The purpose of this study was to investigate the efficacy and safety of SEMLS and to determine if improvements are maintained in the long term.

This study is a large, multi-centre, retrospective, cohort study of children and youth with BSCP with short and long term follow up after SEMLS. Data was collected prospectively, using standardized gait laboratory protocols and analyzed retrospectively, using a summary statistic of gait, the Gait Profile Score (GPS).
