Various indicators of vertebral instability in patients with lumbar degenerative disease can be identified in myelo-computed tomography (CT) studies.
Of 120 patients, 45 with lumbar degenerative spondylolisthesis (LDS; 53 lumbar lesions) and 75 with lumbar spinal stenosis alone (LSS; 105 lesions) (2015-2019) myelo-CT studies and surgery confirmed the presence of lumbar instability. Myelo-CT findings indicative of instability included facet joint thickness (FJT), fluid in the facet joint, facet tropism, and air in the facet and/or disc.
For the 120 study patients, FJT was significantly elevated in both the LDS and LSS groups.
FJT on myelo-CT is more specific for lumbar instability than other imaging parameters when evaluating LDS. An increase in FJT suggests vertebral instability likely warranting fusion.
在脊髓计算机断层扫描（CT）研究中可识别出腰椎退行性疾病患者椎体不稳定的各种指标。
在120例患者中，45例患有腰椎退行性滑脱（LDS；53个腰椎病变），75例仅患有腰椎管狭窄（LSS；105个病变）（2015 - 2019年），脊髓CT研究和手术证实存在腰椎不稳定。脊髓CT上提示不稳定的表现包括小关节厚度（FJT）、小关节内积液、小关节不对称以及小关节和/或椎间盘内积气。
对于120例研究患者，LDS组和LSS组的FJT均显著升高。
在评估LDS时，脊髓CT上的FJT比其他影像学参数对腰椎不稳定更具特异性。FJT增加提示椎体不稳定，可能需要进行融合术。
