We report the use of the second dorsal metacarpal artery-based bilobed island flap harvested from the index and middle fingers for thumb reconstruction. From October 2006 to March 2008, the flap was performed in 13 hands in 13 patients (10 males and 3 females). The mean age at the time of operation was 45 years (range, 38 to 57 years). The flaps of the index fingers ranged in size from 2.1 × 2.5 cm to 4.2 × 3.2 cm. The flaps of the middle fingers were from 2.5 × 2.5 cm to 4.7 × 3.0 cm. The mean pedicle length was 6.5 cm (range, 5.1 to 8.0 cm). Flap survival was achieved in all cases. At final follow-up (mean 43 months; range, 36 to 52 months), the mean static two-point discrimination of the thumb pulps was 7 mm (range, 5 to 10 mm). Our technique is useful and reliable for the thumb reconstruction in select cases, with minimal donor-site morbidity.
我们报告了使用源自食指和中指的第二背侧掌骨动脉双叶岛状皮瓣进行拇指再造。自 2006 年 10 月至 2008 年 3 月，我们对 13 名患者（10 名男性和 3 名女性）的 13 只手进行了该皮瓣手术。手术时的平均年龄为 45 岁（范围，38 至 57 岁）。食指皮瓣的大小范围为 2.1×2.5cm 至 4.2×3.2cm。中指皮瓣的大小范围为 2.5×2.5cm 至 4.7×3.0cm。蒂的平均长度为 6.5cm（范围，5.1 至 8.0cm）。所有病例皮瓣均存活。最终随访（平均 43 个月；范围，36 至 52 个月）时，拇指掌部的平均静态两点辨别觉为 7mm（范围，5 至 10mm）。我们的技术对于选择病例的拇指再造是有用且可靠的，供区并发症少。
