The use of the long palmar muscle in surgeries of muscular transposition and transplantation in orthopedic and plastic surgeries has encouraged the investigation of arterial branches for the long palmar muscle. This study was carried out in 58 upper limbs of child cadavers aged up to one year. It was observed that the muscle was not present in 31.04% of the forearms. It more frequently presents one to two arterial branches which arise mainly, from the ulnar artery (85.71%) and less frequently from brachial artery (22.86%). The arterial branches penetrate the muscle through the posterior face, 62.71% being at the proximal third and 33.90% at the medium third. The most frequent models of the branch disposition were from one to two branches of the ulnar artery which penetrate the proximal thirds (28.57%) and two branches of the ulnar artery, the median and proximal thirds, respectively (17.14%).
在骨科和整形手术中，掌长肌在肌肉转位和移植手术中的应用促使人们对掌长肌的动脉分支进行研究。本研究对58例1岁以下儿童尸体的上肢进行了观察。结果发现，31.04%的前臂不存在该肌肉。该肌肉较常出现一到两支动脉分支，这些分支主要起源于尺动脉（85.71%），较少起源于肱动脉（22.86%）。动脉分支从肌肉后面穿入，62.71%位于近端三分之一处，33.90%位于中间三分之一处。最常见的分支分布模式是一到两支来自尺动脉的分支穿入近端三分之一处（28.57%），以及两支分别来自尺动脉、位于中间和近端三分之一处的分支（17.14%）。
