Review Meta Analysis
The predictive power of the Roussouly classification on mechanical complications after surgery for adult spinal deformity: systematic review and meta-analysis.
With the increasing prevalence of adult spinal deformity (ASD) in the aging population, the need for corrective surgery has surged, highlighting the importance of preventing mechanical complications (MC) such as junctional kyphosis/failure and rod breakage. The Roussouly classification, which categorizes natural variations in spinal posture, may hold predictive value in assessing the risk of these complications, as it guides the restoration of sagittal alignment based on a patient's preoperative spinal shape. ⋯ III.

The purpose of this study was to investigate threshold values for classifying bone as normal or osteoporotic based on Computed Tomography (CT) Hounsfield Units (HU) and to determine if clinically applicable values could be derived to aid spine surgeons evaluating bone quality using CT. ⋯ There is variation in HU values used to differentiate normal from compromised bone quality, even after limiting studies. For patients with HU values between or near 170 or 115 HU, a DEXA scan may be warranted for further evaluation. With ongoing investigation in this area, threshold values for classifying bone quality using CT will be continually refined.

Comparative Study
Adolescent vs. Young Adult Idiopathic Scoliosis patients: how different are their two year postoperative radiographic and clinical outcomes?
To compare the long-term outcomes among AIS (10-18 years) and young AdIS (YAdIS) (19-40 years) patients with minimum 2 year follow up. ⋯ Despite differences in operative characteristics, idiopathic scoliosis (IS) patients who underwent corrective surgery at a younger age had comparable PROMs and 2 year outcomes to older patients. Corrective fusion surgery is safe and effective in both adolescents and young adults and may avoid the higher complication rates seen in older adults.
