A fibrous arch is described between the pisiform bone and the hamulus (arch of Uriburu, arch of hypothenar muscles) (Martinoli et al., 2000). It represents a preferential site of compression of the deep branch of the ulnar nerve (Uriburu et al., 1976). The aim of this work is to show the structure of the arch of the hypothenar muscles.Keywords: macroscopic study, fibrou arch of hypothenarians, structure
