摘　　要：目的提高对腰椎后缘软骨结节(LPMN的认识,着重探讨LPMN对中心椎管、侧隐窝、椎间孔的影响及其伴随改变。方法回顾分析29例LPMN的CT表现。结果32个软骨结节,26例单发,3例多发;中心椎管狭窄27个,其中单纯中心椎管狭窄7个,伴一侧侧隐窝狭窄10个,伴一侧侧隐窝及椎间孔同时狭窄2个,伴双侧侧隐窝狭窄8个;单纯一侧椎间孔、侧隐窝同时狭窄5个。椎间盘突出13个,腰椎滑脱3例,双侧小关节半脱位1例,单侧小关节半脱位及黄韧带肥厚或骨化2例。结论CT不仅能准确反映LPMN对椎管的影响,而且还能明确伴随改变,并能指导手术方式的选择,具有重要的临床价值。Objective To improve the knowledge of LPMN, and lateral recess, intervertebral foramen, and To research of 29 cases LPMN were analysed retrospectively. Restults To research its changes for central lumbar spinal, the companion alters of its. Methods CT findings 32 cartilaginous node; single cartilaginous node （n=26）, multipe cartilaginous node（n=3）; central lumbral spinal canal stenosis（n=27）： single central lumbral spinal canal stenosis（n=7）, the companion single lateral recess stenosis（n=10）, the companion lateral recess and intervertebral foramen stenosis（n=2）, the companion double lateral recess stenosis（n=8）;single lateral recess and intervertebral foramen stenosis（n=5） of companion alters： prolapsed lumbar intervertebral disc （n=13）, slipped lumbal vertebral is 3 cases, double facet dislocation arthropathy is 1 cases, single facet dislocation arthropathy and plump ligament flava or ossification is 2 cases. Conclusion： CT can only precisely shows the changes of LPMN for vertebral canal, and It can make clear the companion alters of its, and It plays an important role in guideing the choice of surgical planning .
