Talus partitus is a rare skeletal developmental abnormality characterized by a split of the posterior talar bone in the coronal plane. Patients with talus partitus typically present with posterior ankle pain and instability, often displaying varying degrees of chondrosis and secondary degenerative change on imaging. To date, only few case reports describing the imaging appearance of talus partitus have been published. The majority of these publications are limited to radiographic and computed tomography (CT) imaging findings, despite the ubiquity of magnetic resonance imaging (MRI). To the authors' knowledge, there is little description of typical MRI findings of the symptomatic talus partitus in the radiologic literature. We present a series of five cases of talus partitus identified on MRI and examine pitfalls in diagnosis, differential considerations, pathophysiology, and treatment options.

距骨（Talus Partitus）：回顾5例经MRI诊断的病例。

距骨是一种罕见的骨骼发育异常，其特征是在冠状平面中距骨的后距骨裂开。距骨距骨患者通常表现为后踝疼痛和不稳定，通常在成像时表现出不同程度的软骨病和继发性退行性改变。迄今为止，仅发表了少量描述距骨影像学表现的病例报告。尽管磁共振成像（MRI）普遍存在，但这些出版物中的大多数仅限于射线照相和计算机断层扫描（CT）成像结果。据作者所知，在放射学文献中很少有症状性距骨的典型MRI表现的描述。我们介绍了一系列在MRI上发现的5例距骨的病例，并检查了诊断中的陷阱，
