Martin-Gruber anastomosis

Mar·tin-Gru·ber a·nas·to·mo·sis

(mahr'tin grū'ber),
a nerve anomaly in the forearm in which motor axons that will ultimately innervate various intrinsic hand muscles supplied by the ulnar nerve, cross from the median nerve (typically its anterior interosseous branch) to the main trunk of the ulnar nerve; also referred to as a median-to-ulnar crossover.
