The computed tomographic (CT) appearance of unfused ossicles in the lumbar spine has had little attention. Unfused ossicles result from accessory ossification centers near the tip of the vertebral processes. Their main importance lies in distinguishing them from fractures. The CT appearance of unfused ossicles in the lumbar spine was correlated with that of the corresponding surface anatomy from a cadaver specimen. Thereafter, 100 consecutive CT studies were reviewed and two cases of presumedly unfused ossicles were found. The CT appearance of unfused ossicles and their differential diagnosis is discussed.
腰椎未融合小骨的计算机断层扫描（CT）表现鲜受关注。未融合小骨源于椎体突尖端附近的副骨化中心。其主要重要性在于将它们与骨折区分开来。腰椎未融合小骨的CT表现与一具尸体标本相应的表面解剖结构相关。此后，回顾了连续100例CT研究，发现了2例疑似未融合小骨的病例。本文讨论了未融合小骨的CT表现及其鉴别诊断。
