Anterior interosseous nerve involvement in a patient due to weight lifting: MRI and EMG finding

摘要

Anterior interosseous syndrome (AINS) is rare and is due to compression of the anterior interosseous nerve, a motor branch of median as a result of trauma at the elbow, often associated with hemorrhage and edema in the deep muscles of the forearm. Patients often present initially with acute pain in the proximal forearm followed by paresis or total paralysis of the pronator quadratus, flexor pollicis longus, and the radial half of the flexor profundus, either individually or together? A complete lesion causes a characteristic deformity of pinch between the thumb and the index finger.121 Depending on the location and the degree of neuronal damage, AIN syndrome can present with a variety of clinical manifestations. This report presents a patient who developed AIN syndrome following weight training of upper extremities.
