500 lumbosacral plain x-ray injured patients and 1000 myelography of patients suffering from low back pain and nerve root sign were reviewed to evaluate the rate of transitional lumbosacral vertebra. This anomaly appeared in 4.6% in the normal population. The rate of the transitional vertebra in patients with nerve root syndrome was double (8.4%) whereas that with lumbar disc herniation four time as many as in the normal population. The data demonstrate that the asymmetrical anomalies have more clinical significance. The authors consider, that the role of the transitional vertebra is twofold: it can be consider primary in low back and sciatic pain, but in the formation of lumbar disc herniation is secondary. They find the analysis of the lumbosacral plain x-ray is necessary even in cases with CT and MRI.
回顾了500例腰骶部X线平片损伤患者以及1000例患有腰痛和神经根体征患者的脊髓造影检查结果，以评估腰骶部移行椎的发生率。这种异常在正常人群中的发生率为4.6%。神经根综合征患者中移行椎的发生率是正常人群的两倍（8.4%），而腰椎间盘突出症患者中移行椎的发生率是正常人群的四倍。数据表明不对称异常具有更大的临床意义。作者认为，移行椎的作用是双重的：在腰腿痛和坐骨神经痛中可被视为原发性因素，但在腰椎间盘突出症的形成中是继发性因素。他们发现即使在有CT和MRI检查的情况下，腰骶部X线平片分析也是必要的。
