OBJECTIVE Proximal junctional kyphosis (PJK) and failure (PJF) are potentially catastrophic
complications that result from abrupt changes in stress across rigid instrumented and mobile …

OBJECTIVE The aim of this study was to investigate the impact of upper instrumented
vertebra (UIV) screw angles on proximal junctional complications in patients with de novo …

Objective The high mechanical stress zone at the sudden transition from a rigid to flexible
region is involved in proximal junctional kyphosis (PJK) physiopathology. We evaluated the …

BACKGROUND Proximal junctional kyphosis (PJK) is a common postoperative complication
after adult spinal deformity (ASD) surgery and may manifest with neurological decline …

When spine surgery is recommended for the correction of a young patient's spinal deformity,
many questions arise from the patient and family. In most cases, they wish to know possible …

ABSTRACT BACKGROUND CONTEXT Proximal junctional failure (PFJ) is a common and
dreaded complication of adult spinal deformity. Previous research has identified parameters …

Study Design. Retrospective cohort study. Objective. The aim of this study was to compare
the incidence of proximal junctional kyphosis (PJK), proximal junctional failure (PJF), and …

Study Design. Retrospective comparative cohort study. Objective. Assess the incidence, risk
factors, and outcomes of recurrent proximal junctional kyphosis (r-PJK) in PJK revision …

Abstract Background Context Proximal junctional kyphosis (PJK) is a challenging
complication after rigid posterior instrumentation (RI) of the spine. Several risk factors have …

Objective A meta-analysis was performed to compare incidence rates of radiographic and
surgical proximal junctional kyphosis (PJK) between upper thoracic (UT) and lower thoracic …
