The classic terminology "osteochondritis dissecans (OCD)" describes a pathologic alteration, centered at the osteochondral junction, involving the subchondral bone and/or its cartilaginous precursor, with risk for lesion instability and disruption of adjacent articular cartilage. Among children and young adults, these sites of osteochondrosis can be a cause of chronic joint pain and are most often found within the knee, the ankle, and the elbow joints. While Part I of this review series focused on shared key definitions, pathophysiologic principles, and imaging considerations, as well as unique differences between lesions at different locations within the knee joint, the current Part II article is devoted to lesions that involve the ankle and elbow joints. Following the outline of the Part I article, an evidence-based literature review on location-specific pathophysiology, imaging considerations, findings of lesion instability, and treatment selection considerations will be discussed for lesions involving the talar dome, capitellum, and humeral trochlea.
经典术语“剥脱性骨软骨炎（OCD）”描述了一种以骨软骨交界处为中心的病理改变，累及软骨下骨和/或其软骨前体，存在病变不稳定和相邻关节软骨破坏的风险。在儿童和年轻人中，这些骨软骨病部位可能是慢性关节疼痛的原因，最常见于膝关节、踝关节和肘关节。本系列综述的第一部分重点关注了共同的关键定义、病理生理原则和影像学考量，以及膝关节不同部位病变之间的独特差异，而当前的第二部分文章则专门讨论累及踝关节和肘关节的病变。按照第一部分文章的大纲，将针对累及距骨穹窿、肱骨小头和肱骨滑车的病变，讨论基于证据的关于特定部位病理生理学、影像学考量、病变不稳定的表现以及治疗选择考量的文献综述。
