Spinal alignment is essential to a well-functioning musculoskeletal system. Normal standing
orientation as defined by Dubousset 1 is with the skull positioned roughly over the femoral …

Study Design Multicenter, prospective cohort Objectives Malalignment following adult spine
deformity (ASD) surgery can impact outcomes and increase mechanical complications. We …

Study Design. Retrospective analysis of prospectively collected data. Objective. Evaluate the
impact of correcting to normative segmental lordosis values on post-operative outcomes …

Purpose Understanding the mechanism and extent of preoperative deformity in revision
procedures may provide data to prevent future failures in lumbar spinal fusion patients …

OBJECTIVE Proximal junctional failure (PJF) is a severe form of proximal junctional
kyphosis. Previous reports on PJF have been limited by heterogeneous cohorts and …

Study Design Multicenter cohort. Objectives A report from the International Spine Study
Group (ISSG) noted that surgeons failed to achieve alignment goals in nearly two-thirds of …

Background Despite numerous studies identifying risk factors for proximal junctional failure
(PJF), risk factors for recurrent PJF (R-PJF) are still not well established. Therefore, we …

Surgical treatment for adult spinal deformity is associated with improved surgical alignment
and improved outcome measures. Unfortunately, complications are a common consequence …

Adult spinal deformity (ASD) is a complex pathology associated with spinal malalignment in
the coronal, sagittal, and axial planes. Proximal junction kyphosis (PJK) is a complication of …

METHODS: We retrospectively reviewed patients with ASD who had undergone revision
surgery for initial PJK/F at a single academic center. Patients were categorized into 2 …
