摘要: |
目的:对人类颈、腰椎关节突关节内“半月板样物”进行形态学和组织学研究。方法:对5具国人成年尸体福尔马林固定标本,2具成人新鲜尸体标本的脊柱颈、腰椎关节突关节。进行手术显微镜下的形态学和光学显微镜下的组织学研究。结果:7具尸体的所有颈椎和腰椎关节突关节内均存在有“半月板样物”。该结构为关节囊滑膜向关节腔内的延伸.充填关节腔的边缘空隙。组织学研究:其结构由滑膜、脂肪和纤维组织构成。在颈椎,自上而下,其结缔组织逐渐增加、变厚.有的深部有钙盐沉积。而在腰椎。所有“半月板样物”均较厚,底部可见大量致密结缔组织,并伴有多少不等的软骨化生和钙盐沉积。结论:在颈、腰椎的活动过程中。该关节内结构的存在可维持关节突关节的动态稳定性:“半月板样物”的厚度.软骨化生和钙化等。与该部位所受到的张力和应力有关;在病理状况下可能是一些临床表现.如“绞锁腰”和“绞锁颈”的病理学基础。 |

Abstract: |
Objective:The micromorphologic and histologic study for the meniscoid of cervical and lumbar zygapophysial joints.Method:Ten cervical and lumbar vertebral columns from embalmed adult cadavers and two cervical and lumbar vertebral columns from fresh frozen adult cadavers were performed micromorphologic and histologic study under the operative and light microscope.Result:The meniscoid occurred in all cervical and lumbar zygapophysial joints of 7 cadavers. The intra-articular structures project from the joint capsule into the joint cavity and fill the subcapsular space. Histologically they are consisted of synovium,adipose and fibrous tissues. The fibrosis tissues in the meniscoid is more abundant in lumbar facet joints than in cervical one.Conclusion: The intra-articular structure may provide the stability of facet joint during flexion and extension. Meniscus entrapment may be a cause of acute locked back and acute locked neck. |
Keywords:cervical and lumbar zygapophysial joints meniscoid acute locked back acute locked neck |
