Resumen
HERRERA, Esperanza et al. Martin-Gruber Anastomosis: Anatomical and electrophysiological issues. Rev. Univ. Ind. Santander. Salud [online]. 2009, vol.41, n.2, pp.157-168. ISSN 0121-0807.
The Martin Gruber Anastomosis (MGA) is one of the most common anatomical variants of the upper limb, which consists of motor axons crossing through the forearm from the median nerve to the ulnar nerve. Phylogenetic and hereditary factors have been associated whit the MGA. However, gender, race, or laterality, do not seem to have importance in the appearance of the communicating branch. The MGA has been categorized according to findings in anatomy, electrophysiology and histology, in relation to the source and destination of the communicating branch. The aim of this article is to review the factors related to the presence of MGA, as well as the descriptions and classifications according to anatomy and electrophysiology. This revision contributes with important information relevant to the recognition of differences between the classic pattern and the variant pattern of the innervations of the intrinsic muscles of the hand. Such recognition allows a more appropriate diagnostic and intervention of disorders of the peripheral nerves in the upper limb. Salud UIS 2009; 41: 157-168
