研究设计：回顾性队列研究目的腰骶移行椎（LSTV）是一种常见的先天性畸形，在腰骶椎正位片上可以准确识别。本研究试图确定这种先天性异常的患病率，并提高所有临床医生的认识，以减少LSTV.Methods患者的手术和程序错误的风险进行了回顾性分析5,941 AP和侧位腰椎X线片。移行椎进行了确定和Castellvi classification.Results下LSTV的患病率在研究人群中为9.9%。腰椎化S1和骶骨化L5分别见于5.8%和4.1%的patients.Conclusion LSTV是一种常见的正常变异，可以是一个因素，在脊柱手术中不正确的水平。重要的是，所有的临床医生都知道这种常见的先天性异常。
Study Design Retrospective cohort study.Objective Lumbosacral transitional vertebrae (LSTV) are a common congenital anomaly, and they can be accurately identified on anteroposterior (AP) radiographs of the lumbosacral spine. This study attempts to determine the prevalence of this congenital anomaly and to increase awareness among all clinicians to reduce the risk of surgical and procedural errors in patients with LSTV.Methods A retrospective review of 5,941 AP and lateral lumbar radiographs was performed. Transitional vertebrae were identified and categorized under the Castellvi classification.Results The prevalence of LSTV in the study population was 9.9%. Lumbarized S1 and sacralized L5 were seen in 5.8 and 4.1% of patients, respectively.Conclusion LSTV are a common normal variant and can be a factor in spinal surgery at incorrect levels. It is essential that all clinicians are aware of this common congenital anomaly.
