Necrosis of skin on the medial side of the great toe has been a significant complication of the great toe nail flap. To investigate the reason for this, a study of the blood supply of the medial side of the great toe was carried out on 55 feet with the injection of red latex into the arteries and on 13 vascular cast specimens. It was found that, after the blood vessels from the plantar and dorsal sides of the great toe are severed during the operation, the skin of the medial side of the great toe is mainly supplied by the medial vascular network at the head of the first metatarsal bone. It is clear that the blood supply from this network may sometimes be insufficient to nourish the skin. It is suggested that the operative incision should be changed so as to increase the blood supply to the medial vascular network which may decrease the incidence of skin necrosis.
拇趾内侧皮肤坏死一直是拇趾甲瓣的一个严重并发症。为了探究其原因，对55只脚进行了拇趾内侧血供研究，向动脉内注入红色乳胶，并对13个血管铸型标本进行了研究。结果发现，在手术过程中切断拇趾足底和背侧的血管后，拇趾内侧皮肤主要由第一跖骨头内侧血管网供血。显然，该血管网的血液供应有时可能不足以滋养皮肤。建议改变手术切口，以增加内侧血管网的血液供应，这可能会降低皮肤坏死的发生率。
