Soft tissue reconstruction around the ankle has been a challenging problem. This article reports our experience using the extensor digitorum brevis muscle flap; some technical variations are discussed.
The extensor digitorum brevis muscle flap is vascularized by the well-defined lateral tarsal artery, a branch of the dorsalis pedis artery originating at the level of the inferior extensor retinaculum. This flap was used for coverage of soft tissue defects in the lower leg and the ankle in 10 patients with various injuries.
All flaps survived completely. Complications included delayed healing of donor skin in two cases. Flap elevation was possible even in the traumatized donor foot.
The advantages of this flap include constant and reliable blood supply, easy and rapid flap dissection, adequate bulk, and one-stage procedure. However, disadvantages include the small size of the flap and the sacrifice of the dorsalis pedis artery.
踝关节周围的软组织重建一直是一个具有挑战性的问题。本文报告了我们使用趾短伸肌肌瓣的经验，并讨论了一些技术变异。
趾短伸肌肌瓣由明确的跗外侧动脉供血，跗外侧动脉是足背动脉的一个分支，起源于伸肌下支持带水平。该肌瓣用于10例不同损伤的小腿和踝关节软组织缺损的覆盖。
所有肌瓣均完全存活。并发症包括2例供区皮肤愈合延迟。即使在供区足部受伤的情况下，也可以掀起肌瓣。
该肌瓣的优点包括血供恒定可靠、肌瓣解剖容易快速、体积足够以及一期手术。然而，缺点包括肌瓣尺寸小和牺牲足背动脉。
