目的：手指严重屈曲挛缩畸形是小儿手烧伤常见后遗症，研究手指背皮瓣修复小儿严重手指屈曲挛缩畸形．方法：切除和松解指掌侧瘢痕，以一侧指背动脉为轴，在同一手指近、中节指背设计皮瓣，远端同达远侧指间关节，宽度可达手指侧中线，由皮瓣远端自伸指肌腱腱膜浅层剥离，形成一小旗状或网球拍状皮瓣，旋转45～90度覆盖指掌侧创面．结果：应用该方法共修复28例59个患指，除3个皮瓣；因指背为萎缩性瘢痕部分坏死外．56个皮瓣全部成活．结论：该皮瓣血运可靠，切取面积大，外形满意，远期效果较稳定．
OBJECTIVE: Severe flexion contracture of fingers is a common sequelae of pediatric hand burns. The study of finger dorsal flaps repairs severe finger flexion contracture in children. Methods: The excision and release of the cochlear scar were performed. One side of the dorsal artery was used as the axis. The flap of the dorsal middling and the dorsal interphalangeal joint were located at the same finger. The width was up to the midline of the finger. From the distal flap from the extensor tendon aponeurosis superficial peel to form a flag-shaped or tennis raccoon flap, rotated 45 to 90 degrees covering the palmar side of the wound. Results: The method was used to repair 28 cases of 59 affected fingers, except 3 flaps; because of the back of the atrophic scar partial necrosis. 56 flaps all survived. Conclusion: The flap is reliable blood supply, cut area, shape satisfactory, the long-term effect is more stable.
