近年来,应用第二足趾再造拇指成功者有许多报导。各家一致认为:手术成功的关键主要是供趾血管的解剖和吻合。为了进一步为这一手术提供形态学的资料,笔者从外科应用的角度,对第二足趾血管和神经的分布情况进行了解剖和观察,现报道如下。 材料和方法 所用材料为甲醛固定的教学用成年尸体下肢52侧(不计性别)。选用10～15％ABS(Cycolac)—丙酮溶液,加红色油彩混合后,经腹主动脉灌注(压力为1.5～2kg/Cm~2),解剖足背动脉、大隐静脉在足部的一段、腓深神经内侧终支和第二足趾的趾底固有神经等;观察它们的走行、分(属)支、分布和相互间的位置关系,并用大分规、游标卡尺、直尺和我院自行设计的血管塞规测量它们的长度、外径和内径。最后将所得数据进行统计处理。
In recent years, there have been many reports of successful thumb reconstruction using a second toe. All agreed that the key to successful operation is the dissection and anastomosis of the toe vessels. In order to further provide morphological information for this operation, the author from the surgical application point of view, the second toe vascular and nerve distribution were dissected and observed, are reported below. MATERIALS AND METHODS Materials used were formalin-fixed adult corpses on the lower 52 sides of the body (excluding sex). Choosing 10 to 15% ABS (Cycolac) -acetone solution, adding red oil color mixture, perfusing abdominal aorta (pressure 1.5 ~ 2kg / cm ~ 2), dissecting the dorsalis pedis artery, The peroneal deep medial terminal branch and the second toe’s sole inherent nerve, etc .; observe their movement, sub (genus) branch, distribution and the mutual relationship between the position, and with a large gauge, vernier caliper, ruler and our own design The vascular plugs measure their length, outer diameter, and inner diameter. Finally, the resulting data for statistical processing.
