Electrophysiological Bracing in Peripheral Nerve Lesions*

Electrophysiological localization of ulnar nerve lesions.

Sensory nerve action potentials in patients with peripheral nerve lesions.

In 1949 Dawson and Scott described a method of examining sensory impulses in human peripheral nerves. By their technique, the median or ulnar nerve at the level of the wrist was stimulated electrically using single shocks, and the action potential of the afferent volley recorded through surface electrodes placed over the nerve trunk at a higher level in the arm. The afferent volley contained bo...

Musculoskeletal ultrasound for peripheral nerve lesions.

Although the combination of a detailed physical examination and a subsequent electrodiagnostic study is used for the diagnosis of peripheral nerve disorders, prompt imaging may also be necessary in daily practice. In this regard, as having higher spatial resolution, and being a faster, more cost-effective and dynamic study; ultrasound (US) has become a very convenient first-line imaging modalit...

Peripheral compression lesions of the ulnar nerve.

ANATOMY The anatomical course of the ulnar nerve renders it particularly vulnerable at the elbow and at the wrist. At both sites the nerve or its terminal branches pass through narrow canals in which small space-occupying lesions may exert pressure. As the nerve crosses the elbow it passes from the extensor aspect of the arm into the flexor mass of the forearm, running between the two heads of ...

Anterior interosseous nerve lesions. Clinical and electrophysiological features.

Lesions of the anterior interosseous nerve in the forearm are rare and often misdiagnosed as tendon injuries. A consecutive series of 13 patients with this condition referred for electrodiagnosis is reviewed. Only three had originally a correct clinical diagnosis and three were initially considered to have tendon ruptures. Five cases were of mechanical origin and seven due to 'neuritis'. All sh...
