Abstract:
Background: Pedicled perforator flaps in the lower leg enable reconstruction of a variety of local defects without microvascular anastomoses and with minimal donor-site morbidity. This study determined the reliable locations of the lower leg perforators.
Methods: Twenty lower limbs harvested from fresh cadavers were used. In 15 specimens, colored latex intra-arterial injections were performed followed by dissection in the suprafascial plane; perforators with a diameter greater than 0.5 mm were located with respect to a line between the tips of the medial and lateral malleoli. In five further specimens, intra-arterial injection of a barium sulfate/gelatin mixture was performed and computed tomographic scans were acquired. Cluster analysis was performed to determine the 5-cm intervals where perforators were most commonly encountered within each septum.
Results: Perforators were located in discrete intermuscular septa. Those arising from the anterior tibial artery were predominantly encountered within three septa, and those of the peroneal and posterior tibial arteries were found within discrete septa. Reliable perforators were found within three distinct 5-cm intervals: at 4 to 9 cm, 13 to 18 cm, and 21 to 26 cm from the intermalleolar line. The anterior tibial artery perforators clustered in the distal and proximal intervals, those of the peroneal artery in the middle interval, and those of the posterior tibial artery in all three intervals.
Conclusions: Reliable perforators from the anterior tibial, posterior tibial, and peroneal arteries can be found in distinct 5-cm intervals within intermuscular septa. This may aid in the design of pedicled perforator flaps of the lower leg.

背景：带蒂的小腿穿支皮瓣可以解决各种各样的局部缺损，不需要吻合微血管，并且可以最大程度的降低供区的损伤

方法：20条新鲜尸体的下肢用做研究。向15例标本的动脉内注射有色凝胶，解剖至筋膜平面，在内外踝尖的顶端的连线上也可见到直径大于0.5 mm的穿支。向另外5例标本动脉内注射硫酸钡和明胶的混合物，然后进行CT扫描。群分析显示：在5cm范围内可以见到大量穿支，且有隔膜隔开
Results: Perforators were located in discrete intermuscular septa. Those arising from the anterior tibial artery were predominantly encountered within three septa, and those of the peroneal and posterior tibial arteries were found within discrete septa. Reliable perforators were found within three distinct 5-cm intervals: at 4 to 9 cm, 13 to 18 cm, and 21 to 26 cm from the intermalleolar line. The anterior tibial artery perforators clustered in the distal and proximal intervals, those of the peroneal artery in the middle interval, and those of the posterior tibial artery in all three intervals
结果：穿支分布于不同的肌间隔。起自胫前动脉的穿支主要位于3个肌间隔，在肌间隔中还可见到起自外侧和胫后动脉的穿支。距踝间有3个不同的范围为5cm的穿支可供应用，分别是：4-9cm,13-18cm,21-26cm。胫前动脉穿支位于近端和远端肌间隔，腓动脉穿支位于中间肌间隔，胫后动脉穿支位于三个肌间隔中。
Conclusions: Reliable perforators from the anterior tibial, posterior tibial, and peroneal arteries can be found in distinct 5-cm intervals within intermuscular septa. This may aid in the design of pedicled perforator flaps of the lower leg.
结论：可供应用的胫前动脉、胫后动脉、腓动脉的穿支位于相聚5cm的不同肌间隔内。这将有助于我们对小腿穿支皮瓣的设计。 小腿带蒂穿支皮瓣的穿支位置和临床应用分析
