Economic Impact of Proximal Junctional Kyphosis

Techniques in Orthopaedics, 2020
Proximal junctional kyphosis (PJK) is a common occurrence after posterior thoracolumbar instrumented spinal fusions for adult spinal deformity (ASD). Despite its relative frequency, PJK’s economic impact has only recently gained appreciation and attention.

Comparison of Proximal Junctional Failure and Functional Outcomes Across Varying Definitions of Proximal Junctional Kyphosis

World Neurosurgery, 2021
Proximal junctional kyphosis (PJK) is a well-recognized complication following surgery for adult spinal deformity (ASD); however, definitions for PJK and its clinical implications can significantly vary by study. This study compares multiple definitions of PJK and describes incidence and clinical significance by definition.From 2014 to 2019, patients ...

Diagnosis and Classification of Proximal Junctional Kyphosis and Proximal Junctional Failure

2017
Technical advancements have allowed the spinal deformity surgeon to achieve newfound abilities to correct severe spinal malalignment. However, proximal adjacent segment pathology (ASP) remains a significant issue. Examples include proximal junctional kyphosis (PJK) and proximal junctional failure (PJF).

Proximal Junctional Kyphosis Symposium: Patient Factors That Can Contribute to Development of Proximal Junctional Kyphosis

Techniques in Orthopaedics, 2020
The development of proximal junctional kyphosis is complex and cannot be attributed to any single factor. The following paragraphs discuss some patient-related factors that have been linked to the development of this condition.

Biomechanical analysis of proximal junctional kyphosis: preliminary results

2012
Proximal junctional kyphosis (PJK) is a complication related to spinal instrumentation. Defined as a pathological kyphosis of levels above the upper instrumented vertebra, PJK is not yet fully understood although many studies have been conducted in this regard.

Prevention of Proximal Junctional Kyphosis After Posterior Surgery of Scheuermann Kyphosis

Journal of Spinal Disorders & Techniques, 2015
A 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

2017
Proximal 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

Spine, 2018
Reliability study of radiographic measures of proximal junctional kyphosis (PJK) in patients with adult spinal deformity (ASD).To assess impacts of level of proximal endpoint and vertebral fracture on reliability of measurement of junctional kyphosis.Radiographic assessment is important in determining management of patients with PJK or proximal ...

Proximal junctional kyphosis above long spinal fusions

Orthopaedics & Traumatology: Surgery & Research
Spinal 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 ...
