STUDY DESIGN: Retrospective, case-control study. OBJECTIVE: Determine risk factors for @entity6081 after surgery for @entity4094 as well as the causative organisms and the results of treatment. SUMMARY OF BACKGROUND DATA: @entity2737 after surgery for @entity4094 is more common than that for @entity2112 . A variety of potential risk factors have been identified, but few have demonstrated statistical significance. METHODS: The Pediatric Orthopedic Spine Database identified 151 @entity1 with @entity4094 who underwent surgery and had a follow-up of minimum of 2 years. A total of eight @entity1 (5.3% prevalence) developed a @entity6081 . Nine @entity1 without an @entity281 were matched by year and type of surgery, for each @entity1 with an @entity281 and selected as controls (n = 72). Preoperative, intraoperative, and postoperative factors were analyzed for an association with wound @entity281 by using stepwise logistic regression. In addition, causative organisms as well as the methods and results of treatment were recorded for each @entity1 . RESULTS.: The control group consisted of 32 males and 40 females with a mean age of 13.3 years (range, 7-21 years) and a mean follow-up of 4.6 years (range, 2.0-20.9 years) at surgery. The @entity281 group (n = 8) consisted of four males and four females with a mean age of 12.5 years (range, 11-14 years) and a mean follow-up of 5.1 year (range, 2.0-12.3 years) at surgery. There were five early and three late wound @entity281 . The presence of a ventriculoperitoneal shunt before surgery was the only factor statistically associated with an increased risk for wound @entity281 (P < 0.01). In addition, @entity281 was associated with @entity1516 (P < 0.01) and an increased length of hospitalization (P < 0.01). The most common causative species was staphylococcus and the majority (88%) of @entity281 required surgical intervention with a mean of 2.1 debridements (range, 1-4 debridements). CONCLUSIONS: The presence of a ventriculoperitoneal shunt is a statistically significant risk factor for wound @entity281 after corrective surgery for @entity4094 . @entity2737 is associated with @entity1516 and prolonged hospitalization. LEVEL OF EVIDENCE: III.
