椎骨骨质增生的形态与组织学观察

Morphological study on the hyperosteogeny structure of the vertebrae

目的：观察椎骨骨质增生与组织结构。方法：在３９０条干燥成人脊柱９７５０块椎骨标本，随机锯３０块增生骨唇经脱钙组织切片或骨磨片，光镜观察。结果：脊柱有骨质增生者２５８付占６６．１％，无骨质增生者１３２付占３３．９％。每块椎骨均可发生骨质增生。镜下观察，Ⅰ度和部分Ⅱ度较短增生骨唇只有骨密质。Ⅲ、Ⅳ和部分Ⅱ度较长的增生骨唇由上、下层骨密质和中层的骨松质三层结构组成，骨密质的骨板排列整齐，骨小梁排列不整齐，网眼大小不一。结论：椎体增生唇可累及其周围的血管神经，椎体增生骨唇可因载荷过重或椎间盘退行性变，椎间关节骨质增生可因椎关节不对称等因素。

Objective:To observe the gross morpholgic and histologic structures of vertebral hyper osteogeny.Methods:390 dry spinal columns(9750 vertebralspecimens) and 30 histological slices of bone labrum of the vertebral body proliferation were observed.Results:There was hyperosteogeny at the edge of vertebral body and intervertebral articulation,but not at the superior and inferior edge of vertebral arcus radix.The small sized bone labrium was composed of compact substance.The middle sized and the large sized were made of compact substance and spongy substance.The compact substance was in the upper strata and the lower of bone labrum,the spongy substance was in the middle of bone labrum.The articular face of intervertebral articulation with hyperosteogeny was full of bumps and holes.Conclusions:The hyperosteogeny can take place at the upper and lower edge of the vertebral body.The spongy substance was one of internal structure of the middle sized and the large sized bone labrium.
