Abstract
INTRODUCTION: Members of the Scoliosis Research Society are required to annually submit complication data regarding deaths, visual acuity loss, neurological deficit and infection (2012-1st year for this measure) for all deformity operations performed. The purpose of this study is to report the 2012 results and the differences in these complications from the years 2009-2012. METHODS: The SRS M&M database is a self-reported complications registry of deformity operations performed by the members. The data from 2009-2012, inclusive, was tabulated and analyzed. Differences in frequency distribution between years were analyzed with Fisher's exact test. Significance was set at α = 0.05. RESULTS: The total number of cases reported increased from 34,332 in 2009 to 47,755 in 2012. Overall mortality ranged from 0.07% in 2011 to 0.12% in 2009. The neuromuscular scoliosis group had the highest mortality rate (0.44%) in 2010. The combined groups' neurological deficit rate increased from 0.44% in 2009 to 0.79% in 2012. Neurological deficits were significantly lower in 2009 compared to 2012 for idiopathic scoliosis >18 years, other scoliosis, degenerative and isthmic spondylolisthesis and other groups. The groups with the highest neurological deficit rates were dysplastic spondylolisthesis and congenital kyphosis. There were no differences in vision loss rates between years. The overall 2012 infection rate was 1.14% with neuromuscular scoliosis having the highest group rate at 2.97%. CONCLUSION: Neuromuscular scoliosis has the highest complication rates of mortality and infection. The neurological deficit rates of all groups combined have slightly increased from 2009 to 2012 with the highest rates consistently being in the dysplastic spondylolisthesis and congenital kyphosis groups. This could be due to a number of factors, including more rigorous reporting.
