Five vertebrae with unilateral spondylolysis are presented. The associated asymmetry of the posterior elements supports the concept of a localised form of growth deficiency. The defect is difficult to demonstrate radiologically, and is perhaps present more frequently than is recognised. It should be suspected clinically from asymmetry of the neural arch and from unilateral wedging of the vertebral body, and may be demonstrated by further radiographic examination. The clinical significance is uncertain, but one patient is presented in whom unilateral spondylolysis was associated with intermittent sciatic pain.
本文展示了五例伴有单侧椎弓根峡部裂的椎体。后部结构的相关不对称支持了局部生长发育不足的概念。该缺损在放射学上难以显示，其实际出现频率可能比目前所认识到的更高。临床上应根据神经弓的不对称以及椎体的单侧楔形改变怀疑该病，进一步的影像学检查可能有助于确诊。其临床意义尚不确定，但本文报道了一例单侧椎弓根峡部裂伴有间歇性坐骨神经痛的患者。
