Thirty-two fresh cadaver hands were perfused with a silicone rubber compound (Microfil) and dissected to explore the vascular and neural anatomy of the hypothenar eminence, in order to assess the possibility for free or pedicled island flaps from this area. In five specimens Microfil was selectively injected into the ulnar palmar digital artery of the little finger to determine the skin territory nourished by this artery. The hypothenar eminence was divided into three territories according to the type of nutrient artery supplying each territory. Among the three territories, the distal half of the ulnar aspect of the hypothenar eminence (approximately 3 x 2 cm), located over the abductor and flexor digiti minimi muscles, had a constant vascular and neural supply from the ulnar palmar digital artery of the little finger and the dorsal or palmar cutaneous branch of the ulnar nerve. This fasciocutaneous area provides a new and feasible donor site for free or pedicled island skin flaps to repair palmar skin defects of the fingers.
对32只新鲜尸体手用硅橡胶化合物（Microfil）进行灌注，并进行解剖以探究小鱼际隆起的血管和神经解剖结构，从而评估从该区域获取游离或带蒂岛状皮瓣的可能性。在5个标本中，将Microfil选择性注入小指的尺侧掌指动脉，以确定该动脉所滋养的皮肤区域。根据供应每个区域的营养动脉类型，将小鱼际隆起分为三个区域。在这三个区域中，小鱼际隆起尺侧的远端半侧（约3×2厘米），位于小指展肌和小指屈肌上方，由小指的尺侧掌指动脉以及尺神经的背侧或掌侧皮支持续供血。该筋膜皮瓣区域为修复手指掌侧皮肤缺损的游离或带蒂岛状皮瓣提供了一个新的可行供区。
