Neurological Comorbidities Predict Proximal Junctional Failure in Adult Spinal Deformity

The Spine Journal, 2017
Retrospective case-control matched cohort from a single institution.To examine the contribution of nonmechanical factors to the incidence of proximal junctional failure (PJF) after adult spinal deformity (ASD) surgery.Multiple studies have reported on the prevalence of PJF following surgery for ASD.

Proximal Junctional Degeneration and Failure Modes

Spine
Study Design. Case-control study. Objective. To introduce a classification system that will include the major types of degenerative changes and failures related to the proximal junction, and to determine the clinical course and characteristics for the different types of proximal ...

The Evaluation, Prevention, and Management of Proximal Junctional Kyphosis and Failure

Journal of the American Academy of Orthopaedic Surgeons
Proximal junctional kyphosis (PJK) occurs commonly after surgery for adult spinal deformity. PJK exists on a spectrum, from a pure radiographic diagnosis to those patients with more severe deformity leading to notable pain, morbidity, and neurologic compromise requiring revision surgery—often described as proximal junctional failure (PJF).

Prevention of Proximal Junctional Kyphosis or Failure: Cement Augmentation

Techniques in Orthopaedics, 2020
Vertebral cement augmentation (vertebroplasty) has recently garnered increasing attention as a possible prophylactic treatment for the prevention of proximal junctional kyphosis and proximal junctional failure in osteoporotic patients undergoing long spinal fusions.

Revision surgery for proximal junctional failure: A single-center analysis

Clinical Neurology and Neurosurgery
Proximal junctional kyphosis (PJK) is a radiographic complication following adult spinal deformity (ASD) surgery due to degeneration of mobile segments adjacent to fused spine. Proximal junctional failure (PJF) represents PJK with structural failure, neurologic deficit, or mechanical instability warranting revision with extension of fusion above the ...

Ligamentous Augmentation to Prevent Proximal Junctional Kyphosis and Failure

Clinical Spine Surgery
Study Design: Biomechanical cadaveric study (level V). Objective: To evaluate the effectiveness of polyethylene bands looped around the supra-adjacent spinous process (SP) or spinal lamina (SL) in providing strength to the cephalad unfused segment and reducing junctional stress.

Proximal junctional degeneration and failure

The Spine Journal
BACKGROUND CONTEXT: Proximal junctional problems occur at high rates after adult spinal fusion, and are often identified as proximal junctional kyphosis/failure (PJK/PJF). Existing classifications are descriptive, but not necessarily correlated with mechanism or clinical course.

Sarcopenia in paraspinal muscle as a risk factor of proximal junctional kyphosis and proximal junctional failure after adult spinal deformity surgery

Journal of Neurosurgery: Spine
OBJECTIVE The aim of this study was to identify the risk factors for proximal junctional kyphosis (PJK) and proximal junctional failure (PJF), including paraspinal muscle atrophy. METHODS Fifty-seven consecutive patients who underwent a long-instrumented fusion for adult spinal deformity (ASD) with a minimum follow-up of 2 years were included in the
