Comparative StudyDo Intraoperative LIV-Tilt and Disk Angle Remain Stable at 2-year Follow-up Compared With Upright Radiographs in Patients With Idiopathic Scoliosis?: A Retrospective Cohort Study.
This study was a retrospective chart and radiographic review. ⋯ Compared with prone intraoperative fluoroscopic images, disk wedging below LIV remains stable at 2 years postsurgery on standing radiographs in patients with AISundergoing PSF, including structural lumbar curves, whereas LIV-tilt improvement is not maintained. Intraoperative fluoroscopy provides a reliable prediction of disk wedging below LIV, 2 years after surgery on standing radiographs.
