Although the pedicled extensor digitorum brevis (EDB) muscle flap is a versatile flap, there are not many reports about it. Furthermore, there are few reports about the reverse vascular flow EDB muscle flap. The lateral tarsal artery coming from the dorsalis pedis artery nourishes the EDB muscle flap. Cutting the dorsalis pedis artery proximal to the flap can elevate this flap with reverse vascular flow. The authors treated eight patients with a reverse vascular flow EDB muscle flap. All flaps survived, with minor repair in two cases. The follow-up period ranged from 4 months to 1 year. This flap has two pivot points for creating a reverse vascular flow pedicled flap and a large arc of rotation for coverage of the dorsal foot. The authors confirmed that this flap is very versatile for soft-tissue reconstruction of the distal dorsum of the foot. The blood supply is reliable and the operative procedure is not complicated and can be performed under regional anesthesia. With this flap, a well-vascularized bed can be prepared for coverage with a skin graft. The major disadvantage is numbness in the first web of the foot, but this does not cause problems in daily life.
尽管带蒂趾短伸肌（EDB）肌皮瓣是一种多功能皮瓣，但关于它的报道并不多。此外，关于逆行血流EDB肌皮瓣的报道也很少。来自足背动脉的跗外侧动脉滋养EDB肌皮瓣。在皮瓣近端切断足背动脉可使该皮瓣以逆行血流方式掀起。作者用逆行血流EDB肌皮瓣治疗了8例患者。所有皮瓣均存活，2例进行了小的修复。随访时间为4个月至1年。该皮瓣有两个用于形成逆行血流带蒂皮瓣的枢轴点和一个用于覆盖足背的大旋转弧。作者证实，该皮瓣在足背远端软组织重建中非常通用。血供可靠，手术操作不复杂，可在区域麻醉下进行。使用该皮瓣可为植皮准备一个血运良好的床面。主要缺点是足第一蹼间隙麻木，但这在日常生活中不会造成问题。
