The os supranaviculare is an accessory bone located on the dorsal aspect of the talonavicular joint close to the midpoint. This rare incidental skeletal variant has an estimated prevalence of 1%. It may rarely become symptomatic and should not be confused with cortical avulsion fractures of navicular or talar head. We present the case of a 25-year-old professional basketball player with pain on the dorsum of his right foot after twisting his ankle during a regular season match. Magnetic resonance imaging findings of the player's foot represented a flake of bone on the superior part of the talar head. The differential diagnosis and clinical outcome of this unusual case are briefly discussed.
舟上骨是位于距舟关节背侧靠近中点处的一块附属骨。这种罕见的偶然骨骼变异估计患病率为1%。它很少会出现症状，不应与舟骨或距骨头的皮质撕脱骨折相混淆。我们报告一例25岁职业篮球运动员的病例，该运动员在常规赛比赛中扭伤脚踝后，右脚背疼痛。该运动员足部的磁共振成像结果显示距骨头上部有一片骨片。本文简要讨论了这一罕见病例的鉴别诊断和临床结果。
