Article Synopsis
- The study examines the impact of implant density on outcomes in posterior spinal fusion surgery for adolescent idiopathic scoliosis (AIS), revealing limited differences between high-density and moderate-density screw constructs.
- A total of 1865 patients were analyzed, showing similar age, sex distribution, and radiographic results, with slight advantages for high-density constructs in curve correction.
- Overall, the findings suggest that moderate-density constructs can be effectively used in routine AIS surgeries, as both densities resulted in comparable patient-reported and radiographic outcomes after two years.
Reoperation Rate After Posterior Spinal Fusion Varies Significantly by Lenke Type.

Background: Lenke curve types can vary in their response to treatment. We explored potential differences in reoperation rates, causes, and risk factors among patients with different Lenke types who underwent posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS).
Methods: We studied a multicenter database of patients with AIS who underwent index PSF at ≤21 years of age and had a minimum 2-year follow-up.
Purpose: Proximal junctional kyphosis is an infrequent complication in AIS; however, equipoise remains on the effects of ending a fusion proximally at the C7-T1 junction on the future development of PJK. The purpose of this study was to determine the rate of PJK in patients with AIS who had a UIV of T1 vs those with a UIV of T2 at 5 years of follow-up.
Methods: A query was performed of a prospective, multi-center AIS database of patients who received a PSF with at least 5 years of follow-up.
Purpose: Anterior vertebral body tethering (VBT) is a non-fusion surgical option for skeletally immature patients with idiopathic scoliosis. Prior studies demonstrated compensatory correction of the thoracic curve after lumbar posterior spinal fusion (PSF); however, no studies have examined thoracic curve correction after lumbar VBT.
Methods: Patients with Lenke 5 + 6 lumbar scoliosis who underwent VBT and at least 2 years' follow-up were compared to matched lumbar PSF patients.
