Two year post-menarche rule for bracing: myth or reality?

Methods We consecutively developed four studies from our clinical prospective database, including 5,142 Females with Idiopathic Scoliosis Patients below the age of 20 years. Results At 2YPM: Risser stage is below 3 in 15.7%, and is still 0 in 2.4%. Growth is not ended and is still decreasing (2.5 cm/y): 5% of patients have 4 cm of residual growth, 12% 3 cm and 25% 2 cm. End of growth is reached around 48 months post-menarche. Scoliosis has not yet finished progressing, particularly in the third year, but also in the subsequent six months. There is no change in the positive results of bracing before and after 2YPM, either for clinical-radiographic results and for percentage of patients improved/ worsened.
