Traumatic Peripheral Nerve Injury in the Philippines: A Retrospective Study.

Background: Traumatic peripheral nerve injury (TPNI) is a debilitating condition that may result in significant disability. There is variability in the epidemiology, clinical profile, and mechanism of injury worldwide, but data for low- and middle-income countries (LMICs) such as the Philippines are sparse. Objective: We aimed to determine the demographic and clinical characteristics, management, and outcomes of patients who sustained TPNI in our center. Methods: We performed a retrospective cohort study of all patients referred for TPNI at our institution from 2013 to 2019. Data on demographics, clinical features, etiology, surgical management, and status on last follow-up were collected. Results: Forty-four patients with injuries to 62 peripheral nerves were included in the cohort, which had a strong male predilection (98%). The mean age at diagnosis was 35.5 years, with 78% of patients aged between 16-45 years. The most common etiologies were laceration due to sharp objects (39%), stab wound (23%), hacking injury (14%), and vehicular crash (14%). In terms of mechanism of nerve injury, the most common was sharp laceration (80%), followed by stretch injury/nerve injury in continuity (14%). The most commonly injured nerves were the ulnar (36%) and median nerves (32%), more often on the right side (66%). Nerve repair surgery was performed in 80% of cases. Conclusion: TPNIs in a tertiary center in the Philippines most commonly involved young males in the working age group and were caused by occupational and domestic accidents. Appropriate surgical management of TPNI is feasible in low resource settings.
