title: Aberrant radial-ulnar nerve communication in the upper arm presenting as an unusual radial nerve palsy: a case report.
abstract: An unusual communication between the radial and ulnar nerves was observed during repair of a fracture of the humerus in an adult patient who presented with unusual physical exam findings. The patient had loss of radial and ulnar nerve motor function, as well as decreased sensation in both nerve distributions. Radial nerve injury following fracture of the humerus is a common condition, and anatomic variations are therefore of importance to clinicians. Communications between branches of the brachial plexus are also not uncommon findings; however there is very little mention of communication between the radial and ulnar nerves in the literature. An appreciation of unusual nerve anatomy is important in explaining unusual finding in patients.
