The Scoliosis Research Society recommends bracing for Risser stages 0\u20132 as Risser stage 3 or above is considered low risk. Very few studies have assessed the risk of progression during bracing in Risser stages 3\u20134. The objective of the current study is to determine if Risser stages 3\u20134 provide a meaningful cutoff in terms of progression risk in patients with AIS treated with night-time bracing.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>AIS patients treated with night-time brace from 2005 to 2018 with a Cobb angle between 25 and 40 degrees and Risser stages 0\u20134 were retrospectively included. Curve progression (&gt;\u20095 degrees increase) was monitored until surgery or SM. Skeletal maturity was defined as either 2\u00a0years postmenarchal, no height development or closed ulnar epiphyseal plates on radiographs.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>One hundred and thirty-five patients were included (Risser stages 0\u20132: <jats:italic>n<\/jats:italic>\u2009=\u200986 and 3\u20134: <jats:italic>n<\/jats:italic>\u2009=\u200949). Overall, radiographic curve progression occurred in 52% while progression beyond 45 degrees was seen in 35%. The progression rate in the Risser 0\u20132 group was 60% and 37% in the Risser 3\u20134 group (<jats:italic>p<\/jats:italic>\u2009=\u20090.012). In multivariate logistic regression analysis, adjusted for Risser stages and age, only premenarchal status showed a statistically significant association with progression (OR: 2.68, 95%CI 1.08\u20136.67).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Risser stage does not provide a clinically meaningful differentiation of progression risk in AIS patients treated with a night-time brace.
