The anatomy of the lateral forearm flap has been studied in 12 fresh cadaver arms with methylene blue and latex injections and arteriography. The posterior radial collateral artery was found to divide constantly into two terminal branches, an anterior and a posterior division. The anterior division is the nutrient vessel of the flap. This artery extends significantly beyond the lateral epicondyle of the elbow into the lateral aspect of the forearm (range 13 to 18 cm, average 15 cm). This allows raising a fasciocutaneous flap in the proximal forearm with a much longer vascular pedicle than the classic lateral arm flap. Other advantages include very thin skin and subcutaneous tissue and less sensory deficit at the donor site. Based on these results, this newly designed lateral forearm flap has been used in 13 clinical cases. Its main indications are whenever soft, thin, pliable skin is needed for small to moderate-sized defects.
通过在12只新鲜尸体手臂上进行亚甲蓝和乳胶注射以及动脉造影,对前臂外侧皮瓣的解剖结构进行了研究。发现桡侧副动脉始终分为两个终末分支,即前支和后支。前支是皮瓣的营养血管。该动脉明显延伸至肘外侧髁之外,进入前臂外侧(范围为13至18厘米,平均15厘米)。这使得在前臂近端掀起一个筋膜皮瓣时,其血管蒂比经典的上臂外侧皮瓣长得多。其他优点包括皮肤和皮下组织非常薄,供区感觉缺失较少。基于这些结果,这种新设计的前臂外侧皮瓣已应用于13例临床病例。其主要适应证是无论何时,对于中小面积缺损需要柔软、薄且柔韧的皮肤时。
