What is the role of plastic surgery for incisional closures in pediatric spine surgery? Results from a pediatric spine study group survey

Current best practice guidelines recommend a plastics-style multilayer wound closure for high-risk pediatric spine surgery. However, plastic surgery closure of spinal incisions remains controversial. This study investigates surgeon perceptions and practice patterns regarding plastic surgery multilayered closure (PMC) in pediatric spine surgery. All surgeons in an international pediatric spine study group received a 30-question survey assessing incisional closure practices, frequency of plastic surgery collaboration, and drain management. Relationship to practice size, setting, geographic region, and individual diagnoses were analyzed. 87/178 (49%) surgeons responded from 79% of participating sites. Plastics utilization rates differed by diagnosis: neuromuscular scoliosis 16.9%, early onset scoliosis 7.8%, adolescent idiopathic scoliosis 2.8% ( P < 0.0001). Plastics were used more for early onset scoliosis [odds ratio (OR) 18.5, 95% confidence interval (CI): 8.5, 40.2; P < 0.001] and neuromuscular scoliosis [OR 29.2 (12.2, 69.9); P < 0.001] than adolescent idiopathic scoliosis. Plastics use was unrelated to practice size, setting, or geographic region ( P ≥ 0.09). Respondents used plastics more often for spina bifida and underweight patients compared to all other indications ( P < 0.001). Compared to orthopaedic management, drains were utilized more often by plastic surgery (85 vs. 21%, P = 0.06) and for longer durations ( P = 0.001). Eighty-nine percent of surgeons felt plastics increased operative time (58 ± 37 min), and 34% felt it increased length of hospitalization. Surgeons who routinely utilize plastics were more likely to believe PMC decreases wound complications ( P = 0.007). The perceived benefit of plastic surgery varies, highlighting equipoise among pediatric spine surgeons. An evidence-based guideline is needed to optimize utilization of plastics in pediatric spine surgery.
