Objective: This study aimed to conduct a systematic review and meta-analysis to assess the
risk factors for proximal junctional kyphosis after the correction surgery of adult spinal …

Adult spinal deformity (ASD) commonly affects older adults, with up to 68% prevalence in
those over 60, and is often complicated by osteoporosis, which reduces bone mineral …

OBJECTIVE Rigid multiplanar thoracolumbar adult spinal deformity (ASD) cases are
challenging and many require a 3-column osteotomy (3CO), specifically asymmetrical …

OBJECTIVE The authors of this study sought to evaluate the predictive role of global sagittal
alignment and upper instrumented vertebra (UIV) level in symptomatic proximal junctional …

OBJECTIVE Deterioration of global coronal alignment (GCA) may be associated with worse
outcomes after adult spinal deformity (ASD) surgery. The impact of fusion length and upper …

Objective To train and validate an algorithm mimicking decision making of experienced
surgeons regarding upper instrumented vertebra (UIV) selection in surgical correction of …

The objectives of fusion surgery for spinal deformities include decompressing neural
elements and achieving balanced spinal alignment. Particularly, in cases where spinal …

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: Retrospective cohort study. Objective: Overcorrection in adult spinal deformity
(ASD) surgery may lead to proximal junctional kyphosis (PJK) because of posterior spinal …

The cervicothoracic junction (CTJ) is a region of the spine submitted to significant
mechanical stress. The peculiar anatomical and biomechanical characteristics make …
