The dorsoradial flap is a recently described cutaneous flap, which is harvested from the distal forearm and indicated for covering dorsal soft tissue defects of the hand and thumb. Vascularization of the flap is assured by a cutaneous branch of the radial artery, which arises at the level of the first intermetacarpal space and supplies the skin of the distal quarter of the forearm dorsum. This area corresponds to the skin island of the dorsoradial flap. We report our clinical experience on seven patients where this flap was used for covering post-traumatic defects of the thumb. Dimensions of the defect varied from 18 to 28 cm(2). The donor site was skin grafted. All flaps survived and provided satisfactory coverage of the defect. Based on a secondary vascular axis, the flap has a large skin paddle and a wide rotation arc that allows soft tissue reconstruction of the dorsal and radiopalmar areas of the thumb.
桡背侧皮瓣是一种最近才被描述的皮瓣，它取自前臂远端，用于覆盖手部和拇指的背侧软组织缺损。该皮瓣的血供由桡动脉的一个皮支提供，此皮支在第一掌骨间隙水平发出，供应前臂背侧远端四分之一的皮肤。这个区域对应桡背侧皮瓣的皮岛。我们报告了7例使用该皮瓣覆盖拇指创伤后缺损的临床经验。缺损面积从18到28平方厘米不等。供区进行了植皮。所有皮瓣均存活，缺损覆盖效果满意。基于第二血管轴，该皮瓣有一个大的皮瓣和宽的旋转弧，可用于拇指背侧和桡掌侧区域的软组织重建。
