Analysis of proximal radial nerve injury in the arm.
BACKGROUND
Radial nerve is the most frequently injured major nerve in the upper extremity. Proximal part of the radial nerve involvement can result from a humerus fracture, direct nerve trauma, compression and rarely from tumors.


OBJECTIVE
The aim of the study is to determine the clinical characteristics and electrodiagnostic findings in patients with proximal radial nerve injuries, and also the outcome of surgical treatment.


METHODS
The study subjects included 46 patients with radial nerve injuries seen between June 2000 and June 2008 at our hospital. The analysis included demographics, clinical features, etiology, pre-and postoperative EMNG (Electromyoneurography) findings.


RESULTS
Surgical decompression resulted in neurological improvement in patients with radial entrapment neuropathies. Good neurological recovery was observed from decompression of callus of old humeral fracture. The worst results were observed in the direct missile injuries of the radial nerve.


CONCLUSIONS
A detailed clinical and electrodiagnostic evaluation is of importance in patients with radial nerve injury to ensure an appropriate treatment. The choice of treatment, conservative or surgical, depends on the clinical presentation and the type of injury.
