下腰椎上关节突及椎弓峡部相关解剖结构测量
Anatomical measurements of the structures relevant to the lumbar spondylolysis articular process and isthmus
目的 采用影像学的方法测量下腰椎中的上关节突以及椎弓峡部的相关解剖结构，并分析新型腰椎后路植骨术操作过程中的安全范围以及其与患者的身高、体重之间的关系。 方法 收集腰椎正侧位X线片正常的成年人300例，男女各150例，采用Digimizer软件测量第3~5腰椎（L3~5）椎体的上关节突的宽度、长度、深度、峡部深度、植骨长度以及绝对深度，并采用线性回归方程法分析这些指标与患者的升高、体重之间是否具有相关性。结果 男、女上关节突的宽度、长度、深度以及峡部的深度和绝对深度与患者的体重和身高之间无明显的相关性，P>0.05；植骨床的长度与身高之间具有显著的相关性，P<0.05，而与体重之间无相关性，P>0.05。 结论 采用影像学法测量下腰椎中的上关节突以及峡部的相关解剖结构，能够为腰椎后路植骨手术操作提供准确、可靠的数据支持。
Objective To measure the structures relevant to the spondylolysis process and isthmus of the lower lumbar spine by using the imaging method, and to analyze the new lumbar posterior planting bone surgery operation in the process of the safety range and the patients with the relationship between the height and weight. Methods Lateral lumbar spine X-ray images were collected from 300 normal adult males and females, 150 each. The width, length, depth, the spondylolysis depth, graft length and absolute depth of the superior articular process of the 3rd-5th lumbar vertebral were measured with the Digimizer software. The equation of linear regression method was used to analyze these indicators and the patients’height and weight. Results The width, length, depth and the depth of spondylolysis and absolute depth of the articular process, and patients’weight and height in both males and females were not correlated (P> 0.05). There was a significant correlation between planting bone bed length and height (P< 0.05), but not the weight (P> 0.05). Conclusion The image method measuring the lower lumbar spine on the joints and outstanding spondylolysis anatomical structure related to posterior lumbar for bone graft operation provides accurate and reliable operation data.
