- Abstract
- Anterior interosseous nerve (AIN) syndrome (AINS) is a clinical condition that arises due to injury of the AIN and presents characteristic weakness of the flexor pollicis longus, radial half of the flexor digitorum profundus, and/or the pronator quadratus. An identical clinical manifestation may also result from fascicular lesions more proximally within the median nerve or brachial plexus (pseudo-AINS). In case of pseudo-AINS due to focal proximal median lesion, however, it is hard to differentiate from the lesion to AIN itself by electrodiagnostic examination. This is a report of two cases of proximal median neuropathy following an axillary brachial plexus block, which clinically mimics AINS. This report shows the importance of knowledge about the fascicular somatotopy in AINS diagnosis.
