摘要
目的 观察腰椎小关节囊的解剖及组织学特点,探讨腰椎活动对关节囊的影响。方法 对5具正常人体腰椎标本进行小关节囊的大体解剖观察;对2例人体新鲜L5小关节囊进行间苯二酚品红-VG染色,观察小关节囊的组织学构成。结果 关节囊外层为均一致密的胶原纤维组织,上下部纤维走行方向不同;中层在关节囊纤维两端有大量弹性纤维分布。结论 复杂的解剖和组织结构使关节囊适于承受来自各个方向的载荷,并可影响小关节力学特性。过度的腰椎旋转易导致小关节囊损伤,这可能是一些临床疗法后腰痛加重的原因。
Objective To describe the anatomical and histological characteristics of the fibrous capsule of human lumbar facet joints. Methods Specimens of the facet joint capsules were obtained from 5 embalmed cadavers for macroscopic investigation, and microscopic observation of L5 facet joint capsules obtained from 2 fresh cadavers was performed after the specimens were stained by way of resorzinoroseine-van Gieson method. Results The outer layer of the fibrous capsule was constituted by dense regular connective tissue that was in turn composed of parallel bundles of collagenous fibers. In the superior part of the joint capsules, the fibers were arranged in the direction different from that taken by the fibers in the inferior part, In the middle layer of the joint capsules, large quantities of elastic fibers were identified in the roots of the capsule. Conclusions The anatomical and histological complexities adapt the lumbar facet joint to better withstand loads from various directions. Immoderate rotatory manipulations may result in capsule injuries, which may aggravate low back pain in some cases.
