Effects 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 کاملProximal 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 کاملExperimental Model of Proximal Junctional Fracture after Multilevel Posterior Spinal Instrumentation
There is a high risk of proximal junctional fractures (PJF) with multilevel spinal instrumentation, especially in the osteoporotic spine. This problem is associated with significant morbidity and possibly the need for reoperation. Various techniques have been proposed in an attempt to decrease the risk of PJF but there is no experimental model described for in vitro production of PJF after mult...
متن کاملCorrelation between multifidus muscle and proximal junctional kyphosis after long-segment instrumentation for lumbar degenerative disease
Background: The purpose of this study was to use magnetic resonance imaging (MRI)-based assessments of multifidus muscle to predict development of proximal junctional kyphosis (PJK). Methods: We retrospectively reviewed 62 patients with lumbar degenerative disease (LDD) who underwent fusion of L5 and all the upper instrumented vertebrae (UIVs) in the thoracolumbar spine (T9-L2), with ≥2 years’ ...
متن کاملBiomechanical Analysis of the Proximal Adjacent Segment after Multilevel Instrumentation of the Thoracic Spine: Do Hooks Ease the Transition?
Study Design Biomechanical cadaveric study. Objective Clinical studies indicate that using less-rigid fixation techniques in place of the standard all-pedicle screw construct when correcting for scoliosis may reduce the incidence of proximal junctional kyphosis and improve patient outcomes. The purpose of this study is to investigate whether there is a biomechanical advantage to using supralami...
