The free os cuboideum secundarium is one of the most rare accessory bones of the foot and is located proximal and plantar to the cuboid. In a 9-year-old boy, a free os cuboideum secundarium of the left foot was resected for persistent pain after trauma. Histologic examination showed degenerative changes of the hyaline cartilage that covered the entire bone. The central spongiosa appeared normal. The patient is free of pain and is still playing football 9.5 years after resection of the accessory bone. Follow-up examination showed no clinical sign of pathology except a soft scar with little discomfort when walking without shoes. Radiographs showed complete remodeling of left cuboid and calcaneus with normal bony configuration of both feet.
游离第二骰骨是足部最罕见的副骨之一，位于骰骨的近端和足底。一名9岁男孩因外伤后持续疼痛，切除了左脚的游离第二骰骨。组织学检查显示覆盖整个骨骼的透明软骨有退行性改变。中央松质骨外观正常。切除副骨9.5年后，患者已无疼痛，仍在踢足球。随访检查显示，除了一个柔软的瘢痕，在不穿鞋行走时有轻微不适外，没有病理的临床迹象。X线片显示左骰骨和跟骨完全重塑，双足骨质结构正常。
