The relationship between clinical features and radiological findings in patients with morphological abnormalities including lumbosacral transitional vertebrae (TV), spina bifida occulta (SBO), and lumbar spondylolysis (LY) was investigated. Materials were 1194 cases including 408 TV, 402 SBO, 162 LY, 85 LY+SBO, 41 LY+TV and 96 SBO+TV. Five hundred cases showing normal structure of lumbosacral spine in X-rays were also studied as a control group. Many of the cases with clinical symptoms showed the low position of the intercrestal line, 34.4% of the patients with incomplete diarthroial joint of TV complained of sciatica or numbness of the leg. The range of motion of the vertebral body directly above TV increased in patients with TV located below the intercrestal line. In many cases of the 5th lumbar spondylolysis, a decrease of the lumbosacral angle and an increase of the pedicle facet angle in the 4th and 5th lumbar vertebrae were observed. In many cases of co-existence of the 5th lumbar spondylolysis and SBO in the 5th lumbar vertebrae, it was observed that a decrease of the lumbosacral angle and the lumbar index and an increase of the pedicle facet angle compared with cases of the 5th spondylolysis.
研究了形态异常患者（包括腰骶部移行椎（TV）、隐性脊柱裂（SBO）和腰椎峡部裂（LY））的临床特征与影像学表现之间的关系。材料包括1194例患者，其中TV 408例、SBO 402例、LY 162例、LY+SBO 85例、LY+TV 41例和SBO+TV 96例。还研究了500例腰骶部脊柱X线结构正常的患者作为对照组。许多有临床症状的病例显示髂嵴连线位置较低，TV关节不完全脱位的患者中有34.4%主诉坐骨神经痛或腿部麻木。位于髂嵴连线以下的TV患者，其上方椎体的活动度增加。在许多第5腰椎峡部裂的病例中，观察到腰骶角减小，第4和第5腰椎椎弓根小关节角增大。在许多第5腰椎峡部裂与SBO并存的病例中，与单纯第5腰椎峡部裂的病例相比，观察到腰骶角和腰椎指数减小，椎弓根小关节角增大。
