腰椎后关节滑膜皱折韧带的神经末梢的病理观察

Pathological examination of nerve endings at synovial fold and ligament of posterior joint of lumbar vertebrae

目的 观察腰椎后关节部位的痛觉感觉器 -游离神经末梢。方法 对 10例腰椎间盘突出伴有腰椎后关节紊乱患者 ,在其椎间盘手术中留取椎后关节及其滑膜标本 ,分别采用HE染色法、硝酸银染色法、氯化金染色法、免疫组化法作病理观察。结果 滑膜皱折、韧带部均具有游离神经末梢。结论 解释了腰椎后关节紊乱症的疼痛部位。

Objective To observe the algesi receptor-free nerve endings at the points of posterior joints of lumbar vertebrae Methods 10 cases of lumbar intervertebral disc herniation (LDH) with disorders of lumbar vertebral posterior joints were selected in this study.During the operation,the specimens of lumbar vertebral posterior joints combined with synovium were obtained for pathological examination by using HE staining method,silver nitrate staining method,auric chloride staining method and immunohistochemical method.Results Free nerve endings could be seen at both synovial folds and ligaments.Conclusion This findings explained why the cases of disorders of the lumbar vertebral posterior joint can not describe the spot of pain and its character exactly.
