Median nerve compression: Pronator and anterior interosseous syndromes
ثبت نشده
چکیده
Proximal compression or neuropathy of the median nerve is rare compared with carpal tunnel syndrome but recognition and management of these conditions is important. Pronator syndrome refers to compression of the median nerve around the elbow, which may present with pain in the forearm and paraesthesia in the hand. Anterior interosseous syndrome (palsy) can result from mechanical compression or inflammatory neuropathy causing significant impairment of dexterity in the hand. Clinical features and the place of neurophysiological testing are discussed. Surgical decompression is indicated when mechanical compression is suspected.

Interosseous Nerve Compression
The anterior interosseous nerve is a branch of the median nerve. It arises from the median nerve just distal to the antecubital fossa, about 5.5 cm distal to the medial epicondyle of the humerus. [2] It passes along the interosseous membrane between the ulna and radius. It terminates in the pronator quadratus muscle around the level of the wrist. It is largely a motor nerve. It supplies the fle...

متن کاملThe incomplete anterior interosseous nerve syndrome.
The anterior interosseous nerve syndrome involves paralysis of the flexor pollicis longus, flexor digitorum profundus of the index and long fingers, and the pronator quadratus. We have encountered 33 cases of an incomplete syndrome in which only the flexor pollicis longus or the flexor digitorum profundus of the index finger is either paretic or paralyzed. This entity must be distinguished from...
متن کاملAnterior Interosseous Nerve Syndrome
Anterior interosseous nerve syndrome (Kiloh-Nevin Syndrome) is the triad of weakness of the flexor pollicis longus, the flexor digitorum profundus of the index finger, and the pronator quadratus. It is a manifestation of neuropathy affecting either the anterior interosseous nerve itself (anterior interosseous neuropathy) or its fascicles more proximally within the median nerve or brachial plexu...
متن کاملPotential Compressive Sites of the Anterior Interosseous Nerve in the Proximal Forearm: An Anatomic Study
Background: The etiology and treatment of spontaneous paralysis variants of anterior interosseous nerve (AIN) syndrome remains controversial. Variation and multiple sites of potential compression complicate the successful performance of neurolysis. This anatomic study of the AIN and sites of potential compression in the proximal forearm facilitates critical steps involved in neurolytic procedur...
