Talus bipartitus is a rare skeletal anomaly that may be mistaken for an os trigonum, a relatively common accessory ossicle found posterior to the talus. Both are believed to be formed similarly with the failed fusion of the talus with a second ossification center. Os trigonum is often diagnosed incidentally or found on radiographs obtained in symptomatic patients with signs of os trigonum syndrome, which presents with posterolateral ankle pain. A bipartite talus may also present with similar symptoms but may be differentiated through its articular involvement.
In this article, we describe the rare presentation of tarsal tunnel syndrome in a patient caused by a bipartite talus. The patient underwent surgical decompression with the removal of the posterior fragment.
A bipartite talus is a rare entity that may be mistaken for an os trigonum, a common accessory ossicle. In this article, we describe an outcome of a bipartite talus fragment removal due to tarsal tunnel syndrome and illustrate a rare pathological consequence of a bipartite talus. We further highlight the importance of early surgical management in patients presenting with an identifiable structure contributing to tibial nerve compression.
距骨二分骨是一种罕见的骨骼畸形，可能被误诊为距骨后三角骨，后者是一种相对常见的副骨。两者都被认为是通过距骨与第二个骨化中心融合失败而形成的。距骨后三角骨通常是偶然诊断出来的，或者在有距骨后三角骨综合征症状的患者的 X 光片上发现，其表现为后外侧踝关节疼痛。二分距骨也可能出现类似的症状，但可以通过其关节受累来区分。
在本文中，我们描述了一例由二分距骨引起的跗管综合征的罕见表现。患者接受了手术减压，切除了后骨块。
距骨二分骨是一种罕见的实体，可能被误诊为距骨后三角骨，这是一种常见的副骨。在本文中，我们描述了由于跗管综合征而切除距骨二分骨的结果，并说明了距骨二分骨的一种罕见病理后果。我们进一步强调了在出现可识别的结构导致胫神经受压的患者中，早期手术治疗的重要性。
