The influence of the magnitude of sagittal correction and local junctional factors on proximal junctional kyphosis and failure following correction of adult spinal deformity: an inverse probability weighted analysis
PJK and PJF remain challenging postoperative complications following correction of ASD. In this large retrospective study that utilized IPW analysis, the authors found factors unique to each outcome. These results suggest that increased correction in the sagittal plane is more commonly associated with PJK, while junctional factors including bone quality and cranially directed screws at the UIV are associated with PJF. These findings can inform pre- and intraoperative medical and surgical strategies to reduce the incidence of PJK and PJF following ASD correction.
