Multicenter Study
Revision Free Loss of Sagittal Correction > 3 Years After Adult Spinal Deformity Surgery: Who and Why?
Multicenter retrospective cohort study. ⋯ Approximately, a quarter of revision-free patients lose an average of 10° of their 6-week correction by 3 years. Lordosis is lost proximally through the instrumentation ( i.e. tulip/shank angle shifts and/or rod bending). The use of supplemental rods and avoiding sagittal overcorrection may help mitigate this loss.

BrAIST-Calc: Prediction of Individualized Benefit from Bracing for Adolescent Idiopathic Scoliosis.
Prospective multicenter study data were used for model derivation and externally validated using retrospective cohort data. ⋯ This externally validated model can be used by clinicians and families to make informed, individualized decisions about when and how much to brace to avoid progression to surgery. If widely adopted, this model could decrease overbracing of AIS, improve adherence, and, most importantly, decrease the likelihood of spinal fusion in this population.
