Cervical facet Hyperplasia and the Ccervical Lordosis Disc CBP® NP#41 Some Chiropractic researchers have hypothesized that facet and odontoid architecture variations can cause a reduction in cervical lordosis. To evaluate this hypothesis, the posterior aspect of the C2 dens, vertebral body corners, and superior and inferior facet surfaces of C2-C7 were digitized on 252 lateral cervical X-rays to calculate global angle, segmental angles, dens angle, facet angles, and facet height. In this study by Chiropractic BioPhysics or CBP Technique researchers; No correlation between facet angle, articular pillar height, and cervical curve was found. Similarly, no correlation between the sagittal angle of the dens and any angle of cervical curvature was found. Thus conservative and surgical rehabilitative techniques aimed at the reduction of sagittal cervical deformities do not need to account for a patient’s architecture of the cervical facets nor odontoid.
Anterior thoracic posture increases thoracolumbar disk loading CBP® NP42 The postural position of the thoracolumbar spine is a major contributor to disc compressive and muscular loads and this in turn can influence low back pain. In this study by Chiropractic BioPhysics researchers, compressive loads on the L5-S1 (lower lumbar) disc nearly doubled in the anterior translated posture. Anterior translation of the thorax resulted in significantly increased loads and stresses acting thon the thoracolumbar spine. this posture is common on lumbar spinal disorders and could contribute to lumbar disc pathologies, progression of 505S1 spondylolisthesis deformities, and poor outcomes after lumbar spine surgery.
