Abstract
The surgical anatomy of interest in the pronator teres syndrome was studied to shed light on the ramifying pattern of the median nerve, the number of its muscular branches and their branching levels and to pinpoint the location of the fibrous bands which may cause median nerve entrapment. The fibrous arch of the pronator teres muscle (pronator arch) was found to lie 3 cm to 7.5 cm below Hueter's line, that of the flexor digitorum superficialis muscle (superficialis arch), which is distal to the pronator arch, was found to lie 6.5 cm below Hueter's line in its most proximal position. Symptom patterns in terms of muscle weakness caused by median nerve entrapment at different levels were also evaluated. L'anatomie chirurgicale relative au syndrome du rond pronateur a été étudiée pour éclairer les modalités de ramification du n. médian, le nombre de ses branches musculaires et leur niveau d'origine, et pour préciser la situation des arcades fibreuses qui peuvent comprimer le n. médian. L'arcade fibreuse du m. rond pronateur a été trouvé'e à 3 à 7,5 cm au-dessous de la ligne de Hueter, celle du m. fléchisseur superficiel des doigts, qui est distale par rapport à celle du m. rond pronateur, a été retrouvée à 6,5 cm au-dessous de la ligne de Hueter dans sa position la plus proximale. Les tableaux cliniques de déficit musculaire causés par la compression du n. médian à divers niveaux sont également analysés.Keywords
