Several types of osseous outgrowths that may appear on the dorsal surface of the talus are described. A normal talar ridge, located between the trochlea and distal articular surface of the talus, may hypertrophy in response to exaggerated stress. In addition, typical osteophytes may appear, indicative of osteoarthritis of the talocrural or talonavicular joint. Finally, a broad excrescence extending distally from the region of the talar ridge represents a sign of tarsal coalition. The location and the appearance of the bony outgrowths differ, allowing precise radiographic diagnosis.
本文描述了几种可能出现在距骨背侧表面的骨性赘生物。位于距骨滑车和远端关节面之间的正常距骨嵴，可能会因过度应力而肥大。此外，可能会出现典型的骨赘，提示胫距关节或距舟关节骨关节炎。最后，从距骨嵴区域向远端延伸的宽大赘生物是跗骨联合的征象。骨性赘生物的位置和外观各不相同，有助于进行精确的影像学诊断。
