Since Adams reported a case of scoliosis relieved by surgery on the transverse process of one of the vertebra in 1910, the clinical significance of lumbosacral transitional vertebrae has been disputed. 22 patients with low back pain and lumbosacral transitional vertebrae with local tenderness over the anomalous lumbosacral articulation were studied. Steroid and local anesthetic injection was performed in the anomalous articulation using fluoroscopy. There was immediate total relief of pain in 19 patients (86.4%). We conclude that lumbosacral transitional vertebrae can be a cause of low back pain.
