短伸肌岛状肌瓣修复胫骨下端软组织缺损6例报告

Repair Soft Tissue Defect of Lower End of Tibia with Extensor Hallucis Brevis Island Flap(a report of 6 cases)

目的:报告伸短肌岛状肌瓣修复胫骨下端软组织缺损的临床应用结果。方法:自2004年9月～2008年1月,应用伸短肌岛状肌瓣修复胫骨下端软组织缺损6例,男4,女2。年龄23～44岁平均31岁,切取的肌瓣面积为2.5cm×3.5cm至3cm×4cm。在肌瓣上行1期中厚网状游离植皮,足部供区直接缝合。结果:所有的肌瓣完全成活,取得了较满意的效果。1例术后发生表浅感染,经换药愈合。结论:该肌瓣具有的血管解剖恒定、血管蒂长和操作简单等优点,而且较薄,适宜修复胫骨下端软组织的缺损。

Objective：To report the clinical results of the repair soft tissue defect of the lower end of the tibia with extensor hallucis brevis island flap.Methods：From September 2004 to January 2008,6 patients（4 men,6 women）with soft tissue defect of the lower end of the tibia underwent reconstruction with extensor hallucis brevis island flap.They ranged in age from 23 to 44 years（mean,31 years）：The sizes of the extensor hallucis brevis was used ranged from 2.5 cm×3.5 cm to 3 cm×4 cm.The immediate coverage of the island flap were performed by a meshed split-thickness skin graft.The foot donor site was closed directly.Results：All the island flaps were survived completely with satisfactory results.One case sustained superficial infection postoperatively.The infection was healed by change dressings.Conclusion：The extensor hallucis brevis island flap seem to has a constant vascular anatomy and a long vascular pedicle,So that dissection of the flap could be accomplished easily.The flap is thin and suitable for repair of soft tissue defect of the lower end of the tibia.
