Abstract：
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.
摘要：
距骨是一种罕见的骨骼发育异常，其特征是距骨后部在冠状平面上分裂。距骨缺损患者通常表现为踝关节后疼痛和不稳定，影像学上常显示不同程度的软骨病和继发性退行性改变。迄今为止,只有很少的病例报告描述了距骨的影像学表现。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）成像发现，尽管磁共振成像（MRI）无处不在。就作者所知，放射学文献中很少描述有症状的距骨的典型MRI表现。我们介绍了一系列5例MRI识别的距骨缺损病例，并检查了诊断中的陷阱，差异考虑，病理生理学,和治疗选择。
