The aim of this study was to characterize the individuals with sacroiliac joint bridging (SIB) by analyzing the degenerative changes in their whole vertebral column and comparing them with the controls. A total of 291 modern Japanese male skeletons, with an average age at death of 60.8 years, were examined macroscopically. They were divided into two groups: individuals with SIB and those withou...
STUDY DESIGN Cross-sectional study. PURPOSE To investigate the relationship between ligamentum flavum (LF) thickening and lumbar segmental instability and disc degeneration and facet joint osteoarthritis. OVERVIEW OF LITERATURE Posterior spinal structures, including LF thickness, play a major role in lumbar spinal canal stenosis pathogenesis. The cause of LF thickening is multifactorial and...

Purpose: To evaluate the safety profile and fusion rates of hollow titanium lumbar zygophyseal fusion cages compared to traditional posterolateral onlay fusion. Methods: In a prospective case controlled study, Group 1 consisted of 30 adult patients who received one or two level lumbar spinal zygapophyseal joint fusions using paired hollow titanium facet joint implants with adjunctive pedicle sc...
PURPOSE The prevalence of radiofrequency zygapophyseal joint neurotomy (RFN) has increased substantially across the past decade. Limited research exists that has examined pre-procedure predictors of RFN outcomes, particularly within workers' compensation populations. The purpose of this study was to determine if pre-procedure biopsychosocial variables are predictive of outcomes in a cohort of c...
Attempts to reconstruct the neutral neck posture of sauropod dinosaurs, or indeed any tetrapod, are doomed to failure when based only on the geometry of the bony cervical vertebrae. The thickness of the articular cartilage between the centra of adjacent vertebrae affects posture. It extends (raises) the neck by an amount roughly proportional to the thickness of the cartilage. It is possible to ...
