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.

Multicenter Study
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.

Retrospective study. ⋯ Level-III.

Multi-centre retrospective cohort study. ⋯ Level 4.

Retrospective chart review. ⋯ This is the first study to measure HU on lumbar CTs in children and adolescents. The technique of measuring BMD in adults should be modified in children by using an ROI that excludes the rarefaction present in the posterior vertebral body. Further studies are needed to evaluate the age-dependent changes in BMD seen in this study.
