Estudio de la vascularización arterial del músculo flexor digitorum superficialis

Abstract

We present an anatomical study that describes the distribution of the muscular perforators of the flexor digitorum superficialis muscle. In this study we dissected 15 forearms fixed according to Thiel method and coloured latex injection in the femoral vessels.The study was centered on the flexor digitorum superficialis muscle. Only muscular perforator arteries with diameters over 2mm were selected. The vascular origin and length were also studied. In all cases, measurements were taken from the bicondyle line. The total number of arteries obtained from the muscle belly was 219, with the greatest percentage located in the half of the forearm. The principal vascular origin of the perforator arteries was the cubital artery. From the results obtained in our work, we can deduce that the ulnar and the ulnar recurrent arteries are the most dominant supply of the muscle. Medially, it receives many large branches from the ulnar recurrent and the ulnar artery. Laterally and proximally, it receives small branches from the median artery, and distally, it receives several small branches from the radial artery that enter the superficial surface of the muscle.
