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 …

Study Design. Retrospective case series of surgically treated patients with adult spine
deformity (ASD). Objective. To report the incidence of proximal junctional failure (PJF) …

OBJECTIVE The incidence of proximal junctional kyphosis (PJK) after long-segment fixation
in patients with adult spinal deformity (ASD) has been reported to range from 17% to 61.7 …

Purpose The purpose of the study is to describe the biomechanical theory explaining
junctional breakdowns in thoraco-lumbar fusions, by taking the example of vertebral …

OBJECTIVE Proximal junctional failure (PJF) is a severe form of proximal junctional
kyphosis. Previous reports on PJF have been limited by heterogeneous cohorts and …

risk factors for proximal junctional failure (PJF) following long instrumented fusion stopping …

Objective To analyze and compare the sagittal spinopelvic alignment variation after
implantation of purely dynamic and hybrid pedicle screw-based stabilization systems …

Study design Assessment of sagittal lordosis distribution on mechanical proximal junctional
failure-related risks through computer-based biomechanical models. Objective To …

Background Thoracolumbar junctional kyphosis (TLJK) due to osteoporotic vertebral fracture
(OVF) negatively impacts patients' quality of life. The necessity of pelvic fixation in corrective …
