Four patients with an os supratrochleare dorsale are presented; three had symptoms that necessitated surgical removal. One patient showed the abnormality in both elbows; three were men and one was a woman. The os supratrochleare dorsale is most likely an accessory bone; however; the location is such that it often becomes traumatized by the olecranon. Posttraumatic pathologic changes with secondary chondrometaplasia of the bone itself occurs as a consequence. Symptomatic patients show posttraumatic changes of the bone, while those without symptoms show a normal trabecular pattern. This condition seems to bear no relation to the supratrochlear septum or to bones in the coronoid fossa.
本文报告了4例背侧滑车上骨患者；其中3例出现了需要手术切除的症状。1例患者双侧肘部均有异常；3例为男性，1例为女性。背侧滑车上骨很可能是一块附属骨；然而，其位置常使其受到鹰嘴的创伤。结果导致骨本身继发软骨化生的创伤后病理改变。有症状的患者表现出骨的创伤后改变，而无症状的患者则表现出正常的小梁模式。这种情况似乎与滑车上隔或冠突窝内的骨无关。
