文题释义:
腰椎痛:是由于比较常见的有腰部骨质增生、骨刺、椎间盘突出症、腰椎肥大、椎管狭窄、腰部骨折、椎管肿瘤、腰部急慢性外伤或劳损、腰肌劳损及强直性脊柱炎等疾病引起的腰部疼痛。
腰椎:椎体较大,棘突板状水平伸向后方,相邻棘突间间隙宽,可作腰椎穿刺用,关节突关节面呈矢状位。人体有5个腰椎,每一个腰椎由前方的椎体和后方的附件组成。椎板内缘成弓形,椎弓与椎体后缘围成椎孔,上下椎孔相连,形成椎管,内有脊髓和神经通过,2个椎体之间的联合部分就是椎间盘。
摘要
背景:
兔腰椎形态结构特点对腰椎动物实验研究起着重要的作用,但目前缺少兔腰椎形态结构相关的研究。
目的:构建兔腰椎三维图像模型,观察其腰椎的形态结构特点,为腰椎动物实验研究提供解剖形态学依据。
方法:用西门子64排螺旋CT扫描20只新西兰大白兔,获得140节腰椎扫描资料,构建兔腰椎三维图像模型,测量L1-7椎体的形态学参数,观察腰椎的内外部解剖结构及不同节段的变化特点。
结果与结论:①新西兰大白兔腰椎各解剖形态学指标变化:兔L1-7节段椎体高度呈现“两头小中间大”趋势,在L7节段最小,其高度仅为(1.12±0.18) cm;L1节段椎体横径最小,为(1.03±0.15) cm,L1-7节段各椎体纵径的节段性变化较小;L1-6节段椎管横径和纵径均逐渐增大,L7节段时突然变小;椎弓宽度在L1-7节段逐渐增大,但变化平稳;椎弓根高度在L1-5节段平稳变化,L6-7节段开始突然变小,与其他节段相差甚大,到L7节段时最小,仅为(0.58±0.11) cm;棘突宽度和长度在L1-6节段平稳增大,在L7节段变小;横突长度在L1-3节段逐渐增大,L3-6节段较平稳,L6-7节段显著变小;横突夹角在L1-6节段差异度小,但在L7节段显著增大,为(58±2)°。②结果证实:新西兰大白兔腰椎形态学测量可以观察到腰椎的内外部解剖结构及不同节段的形态变化特点,为腰椎动物实验研究提供详细的解剖形态学参数资料。

Abstract:

BACKGROUND: Morphological characteristics of the rabbit lumbar vertebrae are of great significance for animal experiments about lumbar spine, but there is a lack of study on the lumbar morphology in rabbits.
OBJECTIVE: To establish a three-dimensional model of rabbit lumbar vertebrae, and to observe its morphological characteristics, thereby providing anatomical basis for the animal experiments about lumbar spine. 
METHODS: Twenty New Zealand rabbits were subjected to 64-row multi-detector CT (Siemens) scan, and the three-dimensional models were constructed based on the CT data from 140 lumbar vertebrae. The morphological parameters of L1-7 were measured, and the internal and external structures of lumbar vertebrae and changes of different segments were observed.
RESULTS AND CONCLUSION: (1) Changes of the morphological parameters of each lumbar vertebra: the L1-7 height first increased and then decreased, and the shortest height was in the L7, which was (1.12±0.18) cm. L1 vertebral body exhibited the shortest transverse diameter, (1.03±0.15) cm, and the longitudinal diameter did not differ significantly among vertebrae. The transverse and longitudinal diameters of L1-6 spinal canals were on a rise, but decreased abruptly at L7. The pedicle width of L1-7 increased gradually; the pedicle height of L1-5 increased gradually, and then began to decrease markedly, and the shortest at L7, (0.58±0.11) cm. The width and length of L1-6 spinous process increased steadily, but decreased at L7. The length of L1-3 transverse process increased gradually, tended to be steady at L3-6, and increased notably at L6-7; there were significant differences in the transverse process angle at L1-6, but the angle increased markedly to (58±2)° at L7, (2) These results indicate that the internal and external structures of lumbar vertebrae and changes of different segments are obtained through morphological measurement of lumbar vertebrae in New Zealand white rabbit, which provides a detailed anatomical data for relative animal experiments.
