Background and objective.

Brachial plexus injuries are devastating lesions for the patient and their environment, with great functional loss. They require multidisciplinary management, complete clinical evaluation and complementary neurophysiological studies, imaging studies or both. In recent decades, the use of intraoperative neuromonitoring has been proposed as a useful tool for brachial plexus surgery, and helps to individualize decision-making in primary reconstruction of brachial plexus injuries.

We describe the experience using different modalities of intraoperative neuromonitoring in patients with brachial plexus injuries in Hospital Universitario San José y Hospital Universitario San José Infantil de Bogotá, Colombia.

Methods.

Retrospective case series, conducted using electronic medical data from Hand Surgery and Microsurgery services, videos and preoperative images taken by the surgeon, and findings described in the report of intraoperative neurophysiological monitoring, of patients with brachial plexus injuries operated in the study period.

Results.

Fourteen patients underwent brachial plexus reconstruction using intraoperative neuromonitoring during the study period: 11 male (78%) and 3 female (22%); 9 (65%) right upper extremity injuries and 5 (35%) left. Age ranged from 19 to 62 years old (average of 33 years). Main etiology was motorcyclist accident. Direct electrical stimulation and stimulated electromyography were used in all patients. Somatosensory evoked potentials were measured in 9 (64%) patients, and transcranial motor evoked potentials were measured in 8 (57%) patients.

Conclusions.

In brachial plexus injuries, intraoperative electrophysiological studies allow better classification of nerve injuries and provide an optimal individualized surgical management, without increasing operative time.
