BACKGROUND: Traumatic injury of peripheral nerves is a worldwide problem and can result in significant disability. Management of peripheral nerve injuries (PNIs) requires accurate localization and the assessment of severity of the lesion. AIM: The purpose of this study is to analyze the data of patients with PNIs referred for electromyography to a tertiary care hospital. MATERIALS AND METHODS: This is a retrospective study of clinical and electromyographic data of patients with PNIs seen over a period of eight-years (1999-2007) in a tertiary hospital. The data collected included: Demographic data, cause, type of lesion, anatomical location of the lesion, and the mechanism of lesion. RESULTS: During the study period 938 patients were seen with nerve injuries and the distribution of nerve injuries was: PNIs: 1,165; brachial plexus lesions: 76; and lumbar plexus lesions: 7. The mean age was 31.8 years (range 2-81 years) and the male to female ratio was 2.4:1. The most frequent nerve injuries were ulnar nerve in the upper extremity and sciatic nerve in the lower extremity. The most common cause of nerve injury was motor vehicle accidents. Two-thirds of the PNIs were partial. CONCLUSION: This study can serve as a guide to determine the epidemiology and classification of traumatic peripheral and plexus injuries.
