腰骶移行椎与胸腰移行椎的关系研究

Relationship between Lumbosacral Transitional Vertebrae and Thoracolumbar Transitional Vertebrae

目的:探讨腰骶移行椎与胸腰移行椎的关系。方法:回顾性分析467例腰骶移行椎患者及450例非腰骶移行椎患者脊柱X线图像,所有患者均用椎体计数金标准进行编号,统计合并胸腰移行椎的例数,分别比较腰骶移行椎组与非腰骶移行椎组患者、腰椎骶化组与骶椎腰化组中胸腰移行椎的发生率;以椎体计数金标准为标准,评估第十二肋定位法的诊断准确度。结果:腰骶移行椎组中胸腰移行椎的发生率为28.6%,明显高于非腰骶移行椎组12.2%;腰椎骶化组中胸腰移行椎的发生率为51%,明显高于骶椎腰化组12.5%;第十二肋定位法的诊断准确率为89.10%。结论:腰骶移行椎与胸腰移行椎之间存在明显相关性,当存在腰骶移行椎时,应考虑合并胸腰移行椎的可能,并用全脊柱图像进行椎体编号。

Objective: The aim of this study is to investigate the association between lumbosacral transitional vertebrae and thoracolumbar transitional vertebrae. Methods: A retrospective analysis was con-ducted, involving the examination of spinal X-ray images from 467 patients with lumbosacral tran-sitional vertebrae and 450 patients without lumbosacral transitional vertebrae. Each patient was assigned a numerical identifier based on the vertebral counting gold standard, and the presence of thoracolumbar transitional vertebrae was documented. The study conducted a comparison of the occurrence of thoracolumbar transitional vertebrae in two distinct groups: the lumbosacral transi-tional vertebra group and the non-lumbosacral transitional vertebra group, as well as in the sacral-ization group and the lumbarization group. The diagnostic accuracy of the twelfth rib localization method was evaluated using the vertebral counting gold standard. The findings revealed a signifi-cantly higher prevalence of thoracolumbar transitional vertebrae in the lumbosacral transitional vertebra group in comparison to the non-lumbosacral transitional vertebra group and the lumbar sacralization group had a significantly higher prevalence of thoracolumbar transitional vertebrae (51%) compared to the sacral lumbarization group (12.5%). The diagnostic accuracy of the twelfth rib localization method was determined to be 89.10%. In conclusion, a significant association exists between lumbosacral transitional vertebrae and thoracolumbar transitional vertebrae. Hence, it is imperative to take into account the potential existence of thoracolumbar transitional vertebrae alongside lumbosacral transitional vertebrae, and utilize full-spinal imaging to ensure precise ver-tebral numbering.
