Abstract

On reviewing the charts of patients with paralysis of the upper extremity, I found a number of cases characterized by a striking uniformity in the pattern of muscles affected. The paralysis was not localized to a main branch of the brachial plexus but involved several smaller branches (exclusive of the ulnar nerve) and always affected the same muscles.

The paralyses of the individual branches of the brachial plexus (the axillary nerve, median, radial, etc.) are well known, and their symptomatology has been investigated sufficiently. The same is not true of paralyses affecting the individual roots of the brachial plexus (the anterior branches of the cervical nerves ). Yet, it would be desirable to know their symptomatology in order to localize lesions more accurately. It must be assumed that each root of the brachial plexus always, or nearly always, contains the same motor and sensory fibers. Thus, one can localize a
