Morphological changes in cervical vertebral body patients with osteoporosis and cervical spondylosis:Case-control study / 中国组织工程研究

ABSTRACT

BACKGROUND:Some scholars have found that cervical vertebral body bone trabecula was reduced,became thin,even perforated in old patients with osteoporosis.Whether this change will induce cervical vertebral body deformation,and what relationship to the onset of cervical syndromeOBJECTIVE:To study the relation of cervical spondylotic myelopathy and osteoporosis by measuring and comparing.METHODS:A totaI of 40 subjects with normal lumbar vertebra density and without cervical spondylosis were enrolled as control group,averagely 32 5 years.A total of 30 patients with cervical spondylosis served as cervical spondylosis group,averagely 43.6 years.Totally 46 patients with cervical spondylosis and osteoporosis served as combined with osteoporosis group,averagely 58.6 years.116 subjects underwent radiograph Height and sagittal diameter of the vertebral body ratio of height to sagittal diameter of the vertebral body.and ratio of sagittal diameter of cervical canal/vertebra body were measured.RESULTS AND CONCLUSION:Compared with the control group.vertebral height was decreased.and sagittal diameter became longer(P＜0.05),and the ratio of sagittal diameter of cervical canal/vertebra body became smaller(P＜0.05)in the combined with osteoporosis group.Vertebral body deformation was characterized by decreased vertebral height and prolonged sagittal diameter became flat.Results suggested that osteoporosis induced cervical vertebral deformation,correlation between osteoporosis and cervical spondylosis,which may be a factor for cervical spondylosis development.
