Late progression of AIS may occur unexpectedly. Even though late bracing of mature patients has not been the standard of care in Canada, AIS patients should be monitored until the very end of growth, despite the low risk of progression, and offered short-term, aggressive, full-time bracing and Schroth physiotherapy if progression unexpectedly occurs. In this case study, short-term, aggressive, full-time bracing combined with daily Schroth physiotherapy proved effective in halting curve progressi

The risk of progression in female patients with AIS decreases as age increases and vertical growth potential decreases 1-2 years post-menarche. Relatively late, unexpected progression of AIS post-menarche could potentially lead to surgery if these patients are managed with observation and left without non-surgical treatment options. Adults with curves <30 degrees have promising outcomes, however, larger curves will progress throughout adulthood an average of 1 degree annually, possibly leading t
