拇指指腹缺损重建后触觉的恢复对手部功能的恢复具有重要意义。本文报道了20例经改良的掌骨第一背动脉岛状皮瓣的临床应用经验，皮瓣由指固有神经桡背支和桡浅神经末梢支支配。结果与常规Foucher第一掌背动脉皮瓣不进行神经修复的25例患者进行比较。在最后的随访中，使用静态两点辨别和semes - weinstein单丝测试评估皮瓣感觉。两组皮瓣均顺利存活。在最后随访时，研究组的静态两点辨别和Semmes-Weinstein单丝测试的平均值与对照组有显著差异。改良的第一掌背动脉岛状皮瓣为拇指指腹缺损的感觉重建提供了可靠和简单的选择。
Restoration of tactile sensation after reconstruction of a thumb pulp defect is import for hand function. We describe our clinical experience using a modified first dorsal metacarpal artery island flap innervated by the radial dorsal branch of the proper digital nerve and the terminal branch of the superficial radial nerve in 20 consecutive cases. The results were compared with 25 patients treated by the conventional Foucher's first dorsal metacarpal artery flap without nerve repair. At the final follow-up, flap sensation was assessed using static two-point discrimination and Semmes-Weinstein monofilament testing. All flaps survived uneventfully in both groups. At the final follow-up, the mean values for static two-point discrimination and Semmes-Weinstein monofilament testing in the study group were significantly different from the values in the control group. The modified first dorsal metacarpal artery island flap provides a reliable and simple option for sensory reconstruction of thumb pulp defects.
