Effect of flexibility and implant density on curve correction in adolescent idiopathic scoliosis

Author(s): Dr. V Surya Prakash Rao and Dr. Jakkepally Sridhar
Abstract: Type of study: Retrospective study Objectives: To evaluate correlation between flexibility, implant density on curve correction in adolescent idiopathic scoliosis Materials and methods: We retrospectively reviewed all consecutive patients of adolescent idiopathic scoliosis who underwent single stage posterior-only correction and instrumented spinal fusion at a single centre between 2013 and 2015 performed by single surgeon. All cases of adolescent idiopathic scoliosis treated with all pedicle screw instrumentation were included. A total of 30 patients were studied, which included 20 females and 10 males. Correlation between implant density, flexibility and curve correction was investigated with pearson correlation coefficient. Results: Average flexibility was 41.86%. Average implant density for rigid curves was 54.49%, flexible curves was 58%. Average curve correction for rigid curve was 60.22%, flexible curves79.56%.The correlation coefficient for curve correction and implant density was 0.096 for flexible curves, 0.075 for rigid curves, both were statistically not significant. The correlation coefficient for flexibility and curve correction was 0.578 for flexible curves and 0.506 for rigid curves which was statistically significant for rigid curves. Conclusion: There was minimal positive correlation correlation between implant density and curve correctability in both flexible and rigid curves not statistically significant. There is positive correlation between flexixibility & curve correctability in both flexible and rigid curves which is significant in rigid curves.
