Experimental 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...

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 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 ...

STUDY DESIGN A retrospective study. OBJECTIVE To analyze the long-term proximal junctional change in adolescent idiopathic scoliosis (AIS) following segmental posterior spinal instrumentation and fusion 5 years or more after surgery. SUMMARY OF BACKGROUND DATA No study has concentrated on time-dependent long-term proximal junctional change in AIS following segmental posterior spinal instrum...
