Wound coverage after a complete degloving injury of the hand and fingers is 1 of the most difficult problems in hand surgery. Important structures such as tendons, nerves, and bones are exposed and will necrose if not covered adequately. The goal of treatment should be coverage with a pliable, sensitive, and cosmetically similar tissue that will allow early mobilization. The authors' experience has led them to adopt the following general guidelines: replantation of the avulsed structures whenever possible; early transfer of a free composite flap from the foot for a complete and irreparable degloving injury of the thumb; and selection of the radial forearm flap for multiple finger lesions. Between 1981 and 1993, 13 patients were treated for degloving injuries of the hand and fingers. Revascularization of the avulsed structures was possible in only 4 patients. In 6 patients with degloving injuries of the thumb in whom replantation was not possible, the thumb was reconstructed using a free wraparound flap from the big toe. In 3 patients with degloving injuries of the fingers, coverage was obtained as an emergency measure using an island radial forearm flap. In conclusion, replantation should be attempted when the degloved skin is available and the vessels are not damaged; secondary reconstruction should be done as early as possible to limit the time of tendon, bone, and joint exposure.
手部及手指完全脱套伤后的创面覆盖是手外科最棘手的问题之一。肌腱、神经和骨骼等重要结构暴露在外,若未得到充分覆盖将会坏死。治疗的目标应是用柔软、敏感且外观相似的组织进行覆盖,以便早期活动。作者的经验使他们采用以下一般原则:尽可能对撕脱的结构进行再植;对于拇指完全且无法修复的脱套伤,早期从足部切取游离复合组织瓣进行移植;对于多个手指损伤,选用桡侧前臂皮瓣。1981年至1993年间,13例患者接受了手部及手指脱套伤的治疗。仅4例患者撕脱的结构得以再血管化。6例拇指脱套伤患者无法进行再植,采用取自拇趾的游离包裹皮瓣重建拇指。3例手指脱套伤患者,作为紧急措施采用岛状桡侧前臂皮瓣进行覆盖。总之,当脱套皮肤可用且血管未受损时应尝试再植;应尽早进行二期重建,以缩短肌腱、骨骼和关节暴露的时间。
