The aim of this study was to identify the prevalence of proximal junctional kyphosis (PJK) in degenerative lumbar scoliosis (DLS) following long instrumented posterior spinal fusion, and to search for predictable risk factors for the progression of junctional kyphosis.In total 98 DLS patients with a minimum 2-year follow-up were reviewed prospectively. According to the occurrence of PJK at the ...

INTRODUCTION Although much attention has been given to the global three-dimensional aspect of adolescent idiopathic scoliosis (AIS), the accurate three-dimensional morphology of the primary and compensatory curves, as well as the intervening junctional segments, in the scoliotic spine has not been described before. METHODS A unique series of 77 AIS patients with high-resolution CT scans of th...

Study Type Retrospective review. Introduction Sagittal imbalance has been associated with lower health-related quality of life outcomes, and restoration of imbalance is associated with improved outcomes.123 The long constructs used in adult spinal deformity have potential consequences such as proximal junctional kyphosis (PJK). Clinically, the development of PJK may not be as important as failu...

An increase of the physiological kyphosis during growth is defined hyperkyphosis (HK) and, according to the level where the apex of the curve can be retrieved, we can distinguish a thoracic HK and a thoraco-lumbar one, also called junctional kyphosis. Since these conditions can cause pain and esthetics impairments, lead in adulthood to an higher incidence of spinal and shoulder pain, and evolve...

OBJECTIVE Serial lengthening with growing rods is recommended every six months for the treatment of early onset scoliosis. The objective of this study was to evaluate the longitudinal growth of the thorax and control of the deformity in a series of patients with juvenile scoliosis when time intervals were increased between lengthenings. MATERIAL AND METHODS Retrospective study of eight patien...
