自1985年以来,根据手指血管神经解剖特点,采用示指桡侧岛状皮瓣修复拇指外伤后组织缺损二例,愈后满意,现介绍如下: 示指桡侧岛状皮瓣是以示指桡侧固有动脉及伴行静脉和神经为蒂,其范围是:远端至示指末节端,近端至掌指关节,其中包括皮肤、皮下组织和浅筋膜。据文献报告,示指桡侧指固有动脉为桡动脉掌深弓的直接分枝,平均内 Since 1985, according to the characteristics of the finger anatomy of the blood vessel, the radial island flap is used to repair the tissue defect after the thumb injury. The more satisfactory, the following is presented: The radial island flap is indicated by the radial Arteries and associated veins and nerves pedicel, its range is: distal to the distal end of the index finger, proximal to the metacarpophalangeal joints, including the skin, subcutaneous tissue and superficial fascia. According to the literature report, the radial artery of the index finger refers to the direct branch of the dorsal radial arch of the radial artery with an average
