Proximal junctional kyphosis (PJK) is a common complication following adult spinal
deformity surgery. It is defined by two criteria: a proximal junctional sagittal Cobb angle (1)≥ …

Aims Postoperative complication rates remain relatively high after adult spinal deformity
(ASD) surgery. The extent to which modifiable patient-related factors influence complication …

To investigate the factors associated with proximal junctional kyphosis (PJK). A systematic
search was performed. The weighted mean difference (WMD) was pooled for continuous …

The purpose of this review is the current understanding of proximal junctional kyphosis
(PJK) and proximal junctional failure (PJF) following adult spinal deformity (ASD) surgery …

Objective. To identify rates and timing of postoperative complications in adult spinal …

Introduction: Proximal junctional kyphosis (PJK) is an acute complication of adult spinal
deformity (ASD) surgery and may require re-operation because of proximal junctional failure …

Purpose Proximal junctional kyphosis (PJK) is a common radiographic finding following long
spinal fusions. Whether PJK leads to negative clinical outcome is currently debatable. A …

Study Design. Case control study. Objective. To evaluate risk factors in patients in 3 groups:
those without proximal junctional kyphosis (PJK)(N), with PJK but not requiring revision (P) …

OBJECTIVE Score on the proximal junctional kyphosis severity scale (PJKSS) has been
validated to show good correlations with likelihood of revision surgery for proximal junctional …

Study Design. A retrospective study. Objective. To analyze time-dependent change of,
