Proximal Junctional Kyphosis and Failure: Strategies for Prevention

Neurosurgery Clinics of North America, 2023
Proximal junctional kyphosis (PJK) and proximal junctional failure/fractures (PJF) are common complications following long-segment posterior instrumented fusions for adult spinal deformity. As progression to PJF involves clinical consequences for patients and requires costly revisions that may undermine the utility of surgery and are ultimately ...

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 ...

Acute proximal junctional failure in patients with preoperative sagittal imbalance

Spine Journal, 2015
Proximal junctional failure (PJF) is a recognized complication of spinal deformity surgery. Acute PJF (APJF) has recently been demonstrated to be 5.6% in the adult spinal deformity (ASD) population. The incidence and rate of return to the operating room for APJF have not been specifically investigated in individuals with sagittal imbalance.The purpose ...

Proximal junctional kyphosis and failure—diagnosis, prevention, and treatment [PDF]

Current Reviews in Musculoskeletal Medicine, 2016
Technical advancements have enabled the spinal deformity surgeon to correct severe spinal mal-alignment. However, proximal adjacent segment pathology (ASP) remains a significant issue. Examples include proximal junctional kyphosis (PJK) and proximal junctional failure (PJF).

Proximal Junctional Kyphosis and Proximal Junctional Failure in the Treatment for Adult Spinal Deformity: Definitions and Epidemiology

Techniques in Orthopaedics, 2020
Proximal junctional failure (PJF) is considered to be one of the most serious complications after correction surgery with a long construct for adult spinal deformity. Proximal junctional kyphosis (PJK) was first defined as an angle between the lower endplate of the uppermost instrumented vertebra (UIV) and the upper endplate of UIV+2 of 10 degrees or ...

Impact of Frailty on the Development of Proximal Junctional Failure

Spine, 2023
Background. Patients undergoing surgery for adult spinal deformity (ASD) are often elderly, frail, and at elevated risk of adverse events perioperatively, with proximal junctional failure (PJF) occurring relatively frequently. Currently, the specific role of frailty in potentiating this outcome is poorly defined.

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).
