To assess the prevalence and degree of lumbosacral transitional vertebrae (LSTV) in the Osteoarthritis Initiative (OAI) cohort, to assess whether LSTV correlates with low back pain (LBP) and buttock pain, and to assess the reproducibility of grading LSTV.
MATERIALS & METHODS: Institutional review board approval was obtained, and informed consent documentation was approved for the study protocol. Standard standing pelvic radiographs that included the transverse processes of L5 were graded according to Castellvi classification of LSTV in 4636 participants (1992 men and 2804 women; aged 45-80 years) from the OAI cohort. These data were correlated with prevalence and severity of LBP and buttock pain.
Prevalence of LSTV was 18.1% (841 of 4636), with a higher rate in men than in women (28.1% vs 11.1%, respectively; P<.001). Of the 841 individuals with LSTV, 41.72% were type I (dysplastic enlarged transverse process), 41.4% were type II (pseudoarticulation), 11.5% were type III (fusion), and 5.2% were type IV (one transverse process fused and one with pseudoarticulation). Of the participants without LSTV, 53.9% reported LBP, while the prevalence of LBP for types I, II, III, and IV was 46%, 73%, 40%, and 66%, respectively (P<.05, χ2 test). Types II and IV had higher prevalence and severity of LBP and buttock pain (P<.001).
LSTV types II and IV positively correlate with prevalence and severity of LBP and buttock pain.
评估 Osteoarthritis Initiative（OAI）队列中腰骶部过渡性椎骨（LSTV）的流行程度和严重程度，评估 LSTV 是否与下腰痛（LBP）和臀部疼痛相关，并评估 LSTV 分级的可重复性。
本研究获得了机构审查委员会的批准，并获得了研究方案的知情同意书。对 OAI 队列中的 4636 名参与者（1992 名男性和 2804 名女性；年龄 45-80 岁）的标准站立骨盆 X 线片进行了评估，这些 X 线片包括 L5 的横突，并按照 Castellvi 分类法对 LSTV 进行了分级。这些数据与 LBP 和臀部疼痛的患病率和严重程度相关。
LSTV 的患病率为 18.1%（4636 例中有 841 例），男性患病率高于女性（分别为 28.1%和 11.1%；P<.001）。在 841 例 LSTV 患者中，41.72%为 I 型（发育不良的增大横突），41.4%为 II 型（假关节形成），11.5%为 III 型（融合），5.2%为 IV 型（一个横突融合，一个假关节形成）。在没有 LSTV 的参与者中，53.9%报告有 LBP，而 I 型、II 型、III 型和 IV 型的 LBP 患病率分别为 46%、73%、40%和 66%（P<.05，卡方检验）。II 型和 IV 型的 LBP 和臀部疼痛患病率和严重程度更高（P<.001）。
LSTV II 型和 IV 型与 LBP 和臀部疼痛的患病率和严重程度呈正相关。
