Our search of the literature on cuboid bone stress fracture in athletes identified three cases reported in English,9 and 10 two cases reported in Japanese,11 and 12 and one case reported in German.13 Including our present case, there are a total of seven cases (Table 1). All fractures occurred in young athletes aged between late teens and twenties, and there was no fixed tendency in the sports involved. All patients recovered by conservative treatments. However, more than 3 weeks were required to arrive at a diagnosis from symptom onset in four of seven cases (including our case), which may suggest a low degree of awareness of this condition. The cases were diagnosed mainly by bone scintigraphy or MRI, showing that diagnosis by plain radiography is difficult.
