Farber SJ, Glaus SW, Moore AM, Hunter DA, Mackinnon SE, Johnson PJ. 1,611,295. The ulnar nerve is critical to hand function because it is responsible for the majority of hand motor function via the intrinsic muscles and provides sensation to the ulnar side of the hand. Studies ranged from between 1999 to 2021. The present authors had the same impression as Dellon and Mackinnon9 that the AIN is more susceptible to compression when it originates from the lateral aspect, and that it is more protected from fibrous arches when it is located posteriorly. Anterior Interosseous Branch of Median Nerve Discussion arises from median nerve, 5 cm above medial epicondyle; runs on volar surface of FDP and along interosseous membrane between ulna & radius; supplies FPL, lateral half of FDP, & pronator quadratus; may supply sensory branches to distal ru and carpal joints; variations: Nyman E, Nyman T, Rubensson C, Thordstein M.

Em dois membros, observou-se a duplicao do nervo intersseo anterior. 7A). The anterior interosseous nerve (volar interosseous nerve) is a branch of the median nerve that supplies the deep muscles on the anterior of the forearm, except the ulnar (medial) half of the flexor digitorum profundus.Its nerve roots come from C8 and T1. Nine studies used supercharged end-to-side transfer as the intervention, 6 used end-to-end transfer, and 1 study compared results between SETS and ETE AIN transfers. Anterior interosseous nerve conduction study: Normative data In all members, it was observed that the anterior interosseous nerve arose from the median nerve proximal to the arch of the flexor digitorum superficialis muscle. Future research should aim to standardise outcomes using validated patient-reported outcome measures and electrodiagnostic tests. No sensory deficits are observed in the clinical evaluation of the hand and forearm.3, 4, It is difficult to determine the etiology of AIN syndrome precisely because there are no signs or clinical tests that can indicate whether it is a compressive neuropathy or a brachial plexus neuritis. Ulnar nerve (b). Anterior Interosseous Syndrome Article The AIN can be compressed by the Struthers ligament; bicipital aponeurosis; fibrous arches between the humeral and ulnar heads of the pronator teres muscle (PT); the fibrous arch formed by the origins of the flexor digitorum superficialis (FDS) muscle; presence of anomalous muscles such as the Gantzer muscle; vascular changes, such as thrombosis or vessel hypertrophy that cross the nerve; tumor formations; cysts; hematomas; abscesses; iatrogenesis in fracture reduction or drugs injected in the forearm; and trauma, such as supracondylar fracture of the humerus and the proximal third of the forearm.3, 4, AIN compressive syndrome is a rare compressive neuropathy of the upper limb.
