Anastomosis between median and ulnar nerve in forearm and hand Article (PDF Available) in Journal of Chemical and Pharmaceutical Research (8) .   Median to ulnar nerve anastomosis in the forearm is referred to as Martin-Gruber Anastomosis (MGA); concomitant MGA and RCCB has been reported, and we have stimulated median nerve in wrist area. Moreover, MGA is a median to ulnar nerve anastomosis; consequently, the presence of concomitant MGA in our study could not interfere with the by: 4. THE SUPERFICIAL ANASTOMOSIS ON THE PALM OF THE HAND BETWEEN THE ULNAR AND MEDIAN NERVES G. P. FERRARI and A. GILBERT From the Orthopaedic Clinic of Padua University, Padua, Italy and French Institute of the Hand, Paris, France The communications between the median and ulnar innervated territories on the palm of the hand have been Cited by: 1. Introduction. The first description of an anastomosis between the median and ulnar nerve in the proximal forearm was in by the Swedish anatomist Martin (). Gruber () estimated its frequency as % in arms. This median-to-ulnar nerve anastomosis in the proximal forearm was later referred to as Martin–Gruber anastomosis (MGA).Cited by:

  Martin–Gruber anastomosis (MGA), or median-to-ulnar nerve communication in the forearm, is not uncommon. The mean incidence is 20%, but incidence has been reported to be as high as 54%. This communication may be bilateral in up to % of cases. The current literature on median to ulnar nerve anastomosis is reviewed, highlighting its frequency and clinical significance making an excellent tool for correct diagnosis in many clinicians. Key words: median nerve; ulnar nerve; nerve anastomosis Introduction Anastomoses between the median (MN) and ulnar nerves.   Communications between peripheral nerves are important in the light of the fact that these are responsible for a myriad of clinical symptoms. Communication between the median nerve and ulnar nerve (Martin-Gruber anastomosis) is a frequent finding observed anatomically in 10%% subjects and physiologically in %.Cited by: 2. • Travels to the ulnar nerve in the forearm following an oblique or transverse course. • Clinical relevance: • In an ulnar nerve injury at a level proximal to the anastomosis, intrinsic ‘ulnar innervated’ hand function will remain preserved because those fibers were traveling with the median nerve and were therefore uninjured.

Connections between deep ulnar & median nerves in hand Ulnar nerve: Lesions.   Median Nerve vs. Ulnar Nerve: MEAT LOAF Median Nerve innervates most Flexor Forearm muscles except: Flexor Carpi Ulnaris and Flexor Digitorum Profundus, which are both innervated by ulnar nerve. Ulnar Nerve innervates most Hand muscles except: L umbricals 1 &2, O pponens Pollicis, A bductor Pollicis Brevis, F lexor Pollicis Brevis (Superficial.   Many authors have reported sensory communication branches between the ulnar and median nerves in the hand. In , Ferrari and Gilbert classified them [ 9 ]. Most authors found the incidence of communication branches between the ulnar and the median nerve to be over 90%, so this kind of anatomical variation should be considered as normal [ 10 ].Cited by: 8.   The communicating branches between the ulnar and median nerve have been described mostly in the hand and arm. A communicating branch of the dorsal and superficial ramus of the ulnar nerve, known as a Kaplan anastomosis, is rare and this is the fourth case to be described in the by: 8.
