Abstract

Abstract : Proximal junctional kyphosis, a complication associated with both pediatric and adult spinal deformity surgical procedures, is defined as a proximal junctional sagittal Cobb angle of ≥10° or a proximal junctional sagittal Cobb angle at least 10° greater than the preoperative measurement. Several risk factors for the development of proximal junctional kyphosis have been identified using univariate analysis, but many of these factors lose significance when examined by multivariate analysis. Future proximal junctional kyphosis studies should include longer follow-up periods and patients with both asymptomatic and symptomatic proximal junctional kyphosis or proximal junctional failure and should examine patient risk factors, spinopelvic parameters, and specific instrumentation techniques.
