The incidence of unfused ossicles in the lumbar spine, in radiographic studies, is 0.7-1.5%. With a sledge cryomicrotome, we sectioned 273 lumbar facet joints in 38 adult cadavers and correlated the anatomic appearance of the joints with CT and magnetic resonance (MR) images. Ossicles were present in 13% of the cadavers and 2.6% of the facet joints and were demonstrated effectively by MR. The incidence of ossicles, which can be confused with fractures, in the facet joints is higher than previously reported.
在放射学研究中，腰椎未融合小骨的发生率为0.7%-1.5%。我们使用雪橇式冷冻切片机对38具成年尸体的273个腰椎小关节进行了切片，并将关节的解剖外观与CT和磁共振（MR）图像进行了对比。小骨存在于13%的尸体和2.6%的小关节中，并且MR能有效显示。小关节中可能被误诊为骨折的小骨发生率高于先前报道。
