Abstract：
To explore the clinical application and efficacy of transplantation of free composite flaps supplied by radial osteocutaneous branch of the dorsal branch of the anterior interosseous artery for reconstructing bone and skin defects in the hand.
Anatomically, the radial osteocutaneous branch of the dorsal branch of the anterior interosseous artery has constant collateral anastomoses which can provide a large dorsoradial flap from the dorsum of the forearm. This flap was used for reconstruction in five cases of cutaneous and phalangeal defects.
Reconstruction was successful in all five cases, with consolidated phalanx and good cosmetic results. All donor sites could be closed directly.
Reconstruction with dorsoradial forearm flaps is a reliable procedure which causes minimal trauma. Thus, it is an ideal approach for repairing cutaneous and phalangeal defects.

摘要：
目的：探讨骨间前动脉背支放射状骨皮支游离复合皮瓣移植重建手部骨缺损和皮肤缺损的临床应用及疗效。
方法：解剖学，骨间前动脉背侧分支的radial骨皮分支具有恒定的侧支吻合，可以从前臂的背侧提供大的背皮瓣。该皮瓣用于5例皮肤和指骨缺损的重建。
结果：所有5例重建均成功，结合方骨和良好的美容效果。所有的捐献者都可以直接关闭。
结论：前臂背皮瓣重建是一种可靠的手术，创伤最小。因此，它是修复皮肤和指骨缺损的理想方法。
