Anterior Interosseous Nerve Syndrome Reconsidered: A Critical Analysis Review

JBJS Rev. 2020 Sep;8(9):e2000011. doi: 10.2106/JBJS.RVW.20.00011.

Abstract

Anterior interosseous nerve syndrome (AINS) represents a form of neuralgic amyotrophy (Parsonage-Turner syndrome). AINS does not originate from external compression of the AIN in the forearm. Fascicular constrictions (FCs) of the median nerve are identified within the anterior interosseous fascicular group at or above the medial epicondyle. Spontaneous recovery is not ensured, leaving up to 30% of patients with permanent weakness or palsy. Fascicular microneurolysis of the median nerve, performed at or above the elbow, is a treatment option for patients who do not recover spontaneously.
