Arterial branches to the Palmaris Longus muscle.
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%).
