To investigate the prevalence of lumbosacral transitional vertebra (LSTV) within the Chinese Han population, and to determine whether LSTV correlates with low back pain (LBP) and gluteal pain.
Typical standing pelvic radiographs were obtained for 5860 volunteers between 18 to 60 years of age. The lumbosacral region of each spine was evaluated to identify LSTV, which was classified into types I, II, III, and IV based on Castellvi's method. Histories of low back symptoms were obtained using a questionnaire. The association of different subtypes of LSTV with LBP and gluteal pain was explored.
LSTV was found in 15.8% (928 of 5860) of our study population. Of the 928 individuals with LSTV, 44.8% were type I (dysplastic transverse process with height >19mm), 43.2% were type II (pseudoarticulation), 7.2% were type III (fusion), and 4.8% were type IV (a unilateral type II transition with a type III fusion on the contralateral side). Type II LSTV were closely associated with LBP and gluteal pain, with respective odds ratios (ORs) of 2.56 (95% CI: 2.17-3.89) and 5.38 (95% CI: 4.29-8.43). Similarly, types IV LSTV also demonstrated a significant correlation with LBP and gluteal pain, with respective ORs of 4.28 (95% CI: 3.21-6.35) and 6.82 (95% CI: 5.17-16.59).
In this population-based study, the prevalence of LSTV was 15.8%, with type I being the most common. Importantly, LSTV types II and IV were significantly associated with LBP and gluteal pain.
调查中国汉族人群中腰骶部移行椎（LSTV）的患病率，并确定LSTV是否与腰痛（LBP）和臀痛相关。
对5860名年龄在18至60岁之间的志愿者进行典型的站立位骨盆X线摄影。对每个脊柱的腰骶部区域进行评估以确定LSTV，根据Castellvi方法将其分为I型、II型、III型和IV型。通过问卷调查获取腰痛症状史。探讨LSTV不同亚型与LBP和臀痛的关联。
在我们的研究人群中，LSTV的患病率为15.8%（5860例中有928例）。在928例LSTV患者中，44.8%为I型（发育异常的横突，高度>19mm），43.2%为II型（假关节），7.2%为III型（融合），4.8%为IV型（一侧为II型移行，对侧为III型融合）。II型LSTV与LBP和臀痛密切相关，各自的比值比（OR）分别为2.56（95%CI：2.17 - 3.89）和5.38（95%CI：4.29 - 8.43）。同样，IV型LSTV也与LBP和臀痛显著相关，各自的OR分别为4.28（95%CI：3.21 - 6.35）和6.82（95%CI：5.17 - 16.59）。
在这项基于人群的研究中，LSTV的患病率为15.8%，I型最为常见。重要的是，II型和IV型LSTV与LBP和臀痛显著相关。
