cervical and upper limb peripheral nerve injuries in adults: electrodiagnostic studies and symptoms

background: peripheral nerve injury (pni), due to upper extremity and cervical trauma can impair hand function, as well as affect quality of life. objectives: in this study we aimed to evaluate clinical symptoms and electrodiagnostic findings in traumatic upper extremity pni. methods: a total of 106 traumatic patients with upper extremity peripheral nerve injuries were recruited and completed a physical examination. in addition, an electrodiagnostic study was performed to investigate detailed pattern of nerve lesions. results: of 106 patients, 88 were males with a mean age of 36.6 ± 14.91. thirty-three patients had an involvement in the forearm area and 20 of them had an injury of the shoulder girdle. twenty-one had ulnar nerve injury, 8 had median, and 8 had radial nerve involvement. furthermore, the ulnar nerve was the most common nerve injury among other nerve involvements. only 10 patients had plexopathy and 10 other had radiculopathy. conclusions: ulnar nerve lesions were highly prevalent in upper limb trauma followed with brachial plexopathy and radiculopathy. the forearm and shoulder girdle are more susceptible to nerve injury.
