【摘要】 1993年以来,根据第1、2掌背动脉血供特点,设计以这二条动脉为血管蒂的第2指蹼分叶岛状皮瓣修复拇指脱套伤5例。皮瓣大小3cm×6cm～6cm×7cm,结果全部成活,伤口一期愈合,术后随访3～9月,皮瓣质薄,有感觉,拇指活动、外形良好。认为此皮瓣对拇指脱套伤的修复很有实用价值。更多还原

【Abstract】 The authors designed a bi-lobed island flap of the second web pedicled with the first and the second dorsal metacarpal arteries.Since 1993,five cases of acute thumb avulsion have been repaired using this flap.The size of the flaps ranged from 3cm×6cm to 6cm×7cm.All flaps survived with prima- ry healing of the incisions.Three to nine months’ follow-up showed that the flaps were thin and had sen- sation.The function and appearance of the reconstructed thumb were satisfactory.The bi-lobed island flap of the second web is a valuable method for the repair of thumb avulsion.更多还原
