OBJECTIVE The aim of this study was to analyze risk factors and avoidance techniques for
proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) in the upper thoracic …

OBJECTIVE Proximal junctional kyphosis (PJK) is a structural complication of spinal fusion
in 5%–61% of patients treated for adult spinal deformity. In nearly one-third of these cases …

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. Retrospective cohort study. Objective. The aim of this study was to investigate
the evolution of proximal junctional kyphosis (PJK) rate over 10-year enrollment period …

Purpose To examine the risk factors of proximal junctional kyphosis (PJK) after surgery for
adult spinal deformity (ASD) focusing on rod contour. Methods Sixty-three patients with ASD …

Background Long fusion to the sacrum has been demonstrated to increase the mechanical
failure rate after adult spinal deformity (ASD) surgery, and these mechanical failures are the …

Study Design: Retrospective cohort study. Objectives: Violation of the posterior soft tissues is
believed to contribute to the development of proximal junctional kyphosis (PJK) …

Study Design. A retrospective study. Objective. To analyze the long-term proximal junctional
change in adolescent idiopathic scoliosis (AIS) following segmental posterior spinal …

Study Design: Retrospective chart review. Objective: The goal of this study is to examine the
relationship between global alignment and proportion (GAP) score and postoperative …

Purpose To analyse the incidence and risk factors associated with proximal junctional
kyphosis (PJK) following spinal fusion, we collect relative statistics from the articles on PJK …
