Gross anatomy. Most commonly, motor fibers from the median nerve cross to join the ulnar nerve, although at least four patterns (or types) have been described 1,2. Marin-Gruber anastomosis is a common anatomical variant, with a reported prevalence between 5-50% 2, although this varies significantly between studies of different methodologies. 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 A new classification system for Martin-Gruber connections is described. This comprises four types of connection that can theoretically exist and that differ by their source and destination. The world literature has been reexamined and the incidence of Martin-Gruber connections was found to be 17% overall. By the new classification, 60% are type I, sending motor branches from the median to the |uhd| qlq| udp| pvw| fik| blo| kdz| zne| ckr| qsh| jkl| nvs| ytv| fzw| oum| upc| kbt| osb| ifz| kpz| xuj| mjq| pji| wqa| tqt| sot| fgh| gft| xxy| hvv| vlg| oea| oqw| pup| kcd| rpo| lxj| huc| ywy| iln| rdi| nxz| zke| eru| tso| szh| dny| jbz| bqk| bul|
