Purpose To evaluate the impact of proximal thoracic segment (T1–T5) on global thoracic
kyphosis, as well as its influence on cervical alignment (lordotic, kyphotic or straight) in …

Purpose To compare the sagittal alignment of patients with diverse mechanical
complications (MCs) following adult spinal deformity (ASD) surgery with that of patients …

Purpose Spinopelvic alignment is increasingly considered as a main factor in the energy-
efficient posture of the individual in normal and pathological status. However, the …

Object Proximal junctional kyphosis (PJK) is a common and significant complication after
corrective spinal deformity surgery. The object of this study was to compare—based on …

Objective To compare the prognostic power of Hounsfield units (HU) and Vertebral Bone
Quality (VBQ) score for predicting proximal junctional kyphosis (PJK) following long …

OBJECTIVE Supine radiographs have successfully been used for preoperative planning of
lumbar deformity corrections. However, they have not been used to assess thoracic …

PURPOSE This study was undertaken to increase the knowledge of the intra-and extra-
spinal alignments and to help recovery of sagittal alignment in operation by measuring the …

Purpose To describe reciprocal changes in cervical alignment after adult spinal deformity
(ASD) correction and subsequent development of proximal junctional kyphosis (PJK). This …

Objective To explore sagittal compensation characteristics, including extra spinal‐pelvic
parameters and distal hip parameters, for analysis in middle‐aged to the older patients with …

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