Proximal junctional kyphosis in adolescent idiopathic scoliosis following segmental posterior spinal instrumentation and fusion minimum 2 years follow-up
Abstract Background: To evaluate proximal junctional segment changes in Adolescent Idiopathic Scoliosis(AIS) the posterior spinal fusion and also instrumentation also and finding of probable risk factors, were all considered in this study. Methods: We retrospectively reviewed radiographs of 121 consecutive patients who underwent posterior spinal fusion for AIS from T3 or below, with...
متن کاملProximal Junctional Kyphosis in Early Onset Scoliosis
In adults and adolescents, proximal junctional failures above deformity constructs have been well established with different risk factors identified; however, the incidence, nature and clinical significance of this kyphosis remains unclear. Several reports in the literature have shed light on PJK in adults and adolescents with variable definition, incidence, prevalence, acuteness, risk factors,...
متن کاملProximal Junctional Kyphosis: Diagnosis, Pathogenesis, and Treatment
Proximal junctional kyphosis (PJK) is a common radiographic finding after long spinal fusion. A number of studies on the causes, risk factors, prevention, and treatment of PJK have been conducted. However, no clear definition of PJK has been established. In this paper, we aimed to clarify the diagnosis, prevention, and treatment of PJK by reviewing relevant papers that have been published to da...
متن کاملEffects of multilevel posterior ligament dissection after spinal instrumentation on adjacent segment biomechanics as a potential risk factor for proximal junctional kyphosis: a biomechanical study
BACKGROUND Spinous processes and posterior ligaments, such as inter- and supraspinous ligaments are often sacrificed either deliberately to harvest osseous material for final spondylodesis e.g. in deformity corrective surgery or accidentally after posterior spinal instrumentation. This biomechanical study evaluates the potential destabilizing effect of a progressive dissection of the posterior ...
متن کاملDiagnosis and Classification of Proximal Junctional Kyphosis and Proximal Junctional Failure
Pedicle screw instrumentation constructs have become a cornerstone in the treatment of adult spinal deformity and instability. They are known to provide greater rigidity and enhanced ability to correct and maintain spinal alignment. Biomechanical data, however, demonstrate that increased construct stiffness is associated with increased loading within adjacent segments [1– 9]. Increasingly stiff...
