摘要:

背景:目前国内外学者对成年中国人第5腰椎峡部作了大量的应用解剖学研究,但研究结果各不相同,并且观测参数不系统、不完整,而对成年中国人第5腰椎峡部进行较系统的临床应用解剖与Micro CT扫描显微影像解剖对照研究国内外文献未见报道。
目的:观测成年中国人第5腰椎峡部Micro CT扫描显微影像解剖学及应用解剖学特点,以期为成年中国人第5腰椎峡部易患病性提供形态学依据。
方法:实验从成都医学院局解实验室随机选取60例成年中国人干燥、无破损第5腰椎标本,应用游标卡尺测量第5腰椎峡部的相关数据,并应用Micro CT的三维重建系统分析第5腰椎标本三维骨结构,并逐一测量与第5腰椎左、右侧峡部临床应用解剖观测的指标相对应的Micro CT扫描显微影像解剖参数。
结果与结论:在成年中国人第5腰椎标本观测: ①左、右侧峡部上缘厚度分别为(4.27±0.99) mm,(4.25± 0.98) mm。②左、右侧峡部下缘厚度分别为(7.31±1.23) mm,(7.29±1.25) mm。③左、右侧峡部内缘厚度分别为(6.61±0.33) mm,(6.59±0.36) mm。④左、右侧峡部外缘厚度分别为(8.65±0.27) mm,(8.59±0.33) mm。⑤左、右侧峡部上下缘距离分别为(11.10±3.14) mm,(11.07±3.11) mm。⑥左、右侧峡部上缘长度分别为(8.37±0.99) mm,(8.40±0.96) mm。⑦左、右侧峡部下缘长度分别为(4.71±0.71) mm,(4.73±0.62) mm。⑧左、右侧峡部内缘长度分别为(13.01±1.38) mm,(13.04±1.36) mm。⑨左、右侧峡部外缘长度分别为(10.75±1.11) mm,(10.78±1.06) mm。游标卡尺与Micro CT所测的第5腰椎峡部左右侧的三维数值之间均差异无显著性意义。结果证实,对成年中国人第5腰椎峡部临床应用解剖测量值与Micro CT测量值之间具有统一性,左右侧腰椎峡部解剖值没有差异,Micro CT能为临床上第5腰椎的易患病性提供更为详尽准确的参考数据。

Abstract:

BACKGROUND: Currently, many scholars have made a large amount of studies on applied anatomy of adult Chinese lumbar isthmus at L5, but study results are diverse. Moreover, parameters were not systematic or complete. No control studies concerned the clinical applied anatomy and Micro CT imaging anatomy on adult Chinese lumbar isthmus at L5.
OBJECTIVE: To observe and measure Micro CT imaging anatomy and applied anatomy on adult Chinese lumbar isthmus at L5 so as to provide morphological evidence for vulnerability of the adult Chinese lumbar isthmus at L5.
METHODS: A total of 60 dried intact adult Chinese lumbar isthmus at L5 specimens were randomly obtained from the Laboratory of Regional Anatomy, Chengdu Medical College. Relevant data of lumbar isthmus at L5 were measured using vernier caliper. Three-dimensional bone architecture of lumbar isthmus at L5 was analyzed using Micro CT three-dimensional reconstruction system. Parameters of Micro CT imaging anatomy corresponding to the applied anatomy of left and right lumbar isthmus at L5 were measured.
RESULTS AND CONCLUSION: Measurement on adult Chinese lumbar isthmus at L5 was performed: ① The thicknesses of upper border of left and right isthmus were respectively (4.27±0.99) mm and (4.25±0.98) mm. ② The thicknesses of lower border of left and right isthmus were respectively (7.31±1.23) mm and (7.29±1.25) mm. ③ The thicknesses of inner border of left and right isthmus were respectively (6.61±0.33) mm and (6.59±0.36) mm. ④ The thicknesses of exterior border of left and right isthmus were respectively (8.65±0.27) mm and (8.59±0.33) mm. ⑤ The distances of upper and lower borders of the left and right isthmus were respectively (11.10±3.14) mm and (11.07±3.11) mm. ⑥ The lengths of upper border of the left and right isthmus were respectively (8.37±0.99) mm and (8.40±0.96) mm. ⑦ The lengths of lower border of the left and right isthmus were respectively (4.71±0.71) mm and (4.73±0.62) mm. ⑧ The lengths of inner border of the left and right isthmus were respectively (13.01±1.38) mm and (13.04±1.36) mm. ⑨ The lengths of exterior border of the left and right isthmus were respectively (10.75±1.11) mm and (10.78±1.06) mm. No significant difference in the three-dimensional values of the left and right isthmus at L5 measured by vernier caliper and Micro CT was detected. Results verified that the measure values measured by vernier caliper and Micro CT on adult Chinese lumbar isthmus at L5 were uniform, and no significant difference was detectable between the left and right sides. Micro CT provides precise reference evidence for the vulnerability of L5 vertebra in the clinic.
