Prevention of Proximal Junctional Kyphosis After Posterior Surgery of Scheuermann Kyphosis
Journal of Spinal Disorders & Techniques, 2015A prospective randomized study.To introduce an operative technique that prevents proximal junctional kyphosis (PJK) in Scheuermann disease after a segmental posterior spinal instrumentation and fusion.PJK is the progression of kyphotic deformity at the proximal end of a construct >10 degrees, and it can be seen up to 30% after posterior Scheuermann ...

Prevention Strategies for Proximal Junctional Kyphosis
2017Proximal junctional kyphosis (PJK) is a well-recognized complication following posterior spinal instrumentation and fusion in patients undergoing surgery for adult spinal deformity (ASD). Broadly, PJK is defined as abnormal kyphosis within the vertebrae adjacent to the upper-instrumented vertebra (UIV) of the fusion.

Proximal junctional kyphosis above long spinal fusions
Orthopaedics & Traumatology: Surgery & ResearchSpinal deformity in adults is a major public health problem. After failure of conservative treatment, correction and fusion surgery leads to clinical and radiological improvement. However, mechanical complications and more particularly - proximal junctional kyphosis (PJK) - are common with an incidence of 10%-40% depending on the studies.Several risk ...

The Evaluation, Prevention, and Management of Proximal Junctional Kyphosis and Failure
Journal of the American Academy of Orthopaedic SurgeonsProximal 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).

Distinct Mechanisms of Proximal Junctional Kyphosis and Their Clinical Implications
SpineStudy Design. Retrospective cohort study Objectives. In patients undergoing adult spinal deformity (ASD) surgery, we sought to: (1) describe mechanisms of Proximal junctional kyphosis/failure (PJK/F), and (2) compare time-to-diagnosis,

Adjacent Level Disease and Proximal Junctional Kyphosis
2016Adjacent segment disease following lumbar spinal fusion refers to any symptomatic pathology occurring rostral or caudal to a previous fusion. The exact etiology of adjacent segment disease is controversial with evidence implicating increased biomechanical forces on the neighboring functional segmental unit as well as an intrinsic degenerative ...

Proximal junctional failure following surgical correction for adult spinal deformity significantly impacts quality of life and increases the economic burden of treating underlying spinal deformity. The objective of this cadaver study was to determine optimal tension parameters in junctional tethers for proximal junctional kyphosis prevention.Cadaveric ...
