STUDY DESIGN: Retrospective review of a prospectively collected, multicentered database from the Scoliosis Research Society. OBJECTIVES: To evaluate incidences of complications in a series of spinal fusions for Scheuermann kyphosis (SK) and to assess whether the incidence of complications is associated with patient age and surgical approach. SUMMARY OF BACKGROUND DATA: Although there is some evidence that adolescents have lower complication rates for spinal deformity surgery, this has not been well-documented for SK. Moreover, there is a lack of consensus on surgical approach for the management of SK. METHODS: The Scoliosis Research Society morbidity and mortality database was queried to identify cases of SK from 2001 to 2004. Complications rates were analyzed based on patient age and surgical approach. Pediatric and adult patients were defined as 19 year old, respectively. RESULTS: A total of 683 procedures involving spinal fusion for SK were identified. Mean patient age was 21 years (range: 5-75 years), with the majority (73%) of patients
