Lumbosacral transitional vertebrae is a common congenital anomalous condition of the spine. Recent advances in magnetic resonance imaging have made it possible to acquire images of the whole spine. This study aimed to find out the prevalence of lumbosacral transitional vertebrae amongst the individuals undergoing magnetic resonance imaging of the whole spine in a tertiary care hospital.
A descriptive cross-sectional study was conducted in 750 patients of all age groups who underwent magnetic resonance imaging of the whole spine in the Department of Radiodiagnosis and Imaging, Kathmandu University School of Medical Sciences from 7th November, 2019 to 6th November, 2020. Convenience sampling technique was used. Ethical approval was taken from the Institutional Review Committee (Reference number 207/19). Data was analysed using Statistical Package for Social Sciences version 22. Point estimate at 95% Confidence Interval was calculated along with frequency and percentage.
Lumbosacral transitional vertebra was seen in 98 (13.10%) (95% Confidence Interval= 10.61-15.51) of the total 750 individuals. Out of the 98 patients who had lumbosacral transitional vertebra, 31 (4.10%) had lumbarization of S1 vertebra and 67 (8.94%) had sacralization of L5 vertebra.
Prevalence of lumbosacral transitional vertebrae amongst the individuals undergoing magnetic resonance imaging of the whole spine in our hospital was similar to other study done in similar settings. Lumbosacral transitional vertebrae are a common congenital anomalous condition of the spine that is identified incidentally. Enumeration of vertebrae from the first cervical vertebra using whole spine magnetic resonance imaging can confirm the presence of the lumbosacral transitional vertebrae with much accuracy.
腰骶部过渡椎是脊柱常见的先天性异常。磁共振成像的最新进展使得对整个脊柱进行成像成为可能。本研究旨在确定在一家三级保健医院进行全脊柱磁共振成像的个体中腰骶部过渡椎的发生率。
在 2019 年 11 月 7 日至 2020 年 11 月 6 日期间，在加德满都大学医学院放射诊断和影像系对所有年龄段的 750 例接受全脊柱磁共振成像的患者进行了描述性横断面研究。使用方便抽样技术。获得了机构审查委员会的伦理批准（参考编号 207/19）。使用社会科学统计软件包 22 版分析数据。计算了点估计值（95%置信区间），以及频率和百分比。
在 750 名个体中，有 98 名（13.10%）（95%置信区间= 10.61-15.51）存在腰骶部过渡椎。在 98 例有腰骶部过渡椎的患者中，31 例（4.10%）为 S1 腰椎化，67 例（8.94%）为 L5 骶椎化。
我们医院进行全脊柱磁共振成像的个体中腰骶部过渡椎的发生率与其他类似环境下的研究相似。腰骶部过渡椎是脊柱常见的先天性异常，通常是偶然发现的。使用全脊柱磁共振成像从第一颈椎计数椎体可以更准确地确认腰骶部过渡椎的存在。
