Descriptive Characteristics and Injury Patterns of Earthquake-Related Peripheral Nerve Injuries in the Extremities

Abstract

Background/Aims:Due to the prioritization of limb and life-saving efforts by medical teams, peripheral nerve injuries (PNIs) resulting from earthquakes are frequently overlooked or receive delayed treatment. Thus, we examined earthquake-related PNIs in terms of their descriptive characteristics and injury patterns Methods: The study was conducted retrospectively in a tertiary hospital after Kahramanmaraş Earthquakes. The study included victims under rubble admitted to the hospital and diagnosed with PNI according to their medical records between 06 February and 28 February 2023. Results: The study included 70 patients and a total of 98 limbs with PNIs, with a mean patient age of 22.31±14.91 years. 77.6% (n=76) of PNIs involved the lower limb (68 peroneal and 8 sciatic nerves) and 22.4% (n=22) of PNIs involved the upper limbs (14 radial nerves, 5 ulnar nerves, 2 median nerves, 1 brachial plexus). It was found that 45.9% of PNIs (n=45) occurred in the right and 54.1% (n=53) in the left extremities. The median time under the rubble of the patients was 15 hours (IQR 8.75 - 32 hours). Fasciotomy was treated in 54.1% (n=43) of the extremities with PNI. Fasciotomies were most commonly performed on the cruris (42.9%), foot (26.5%), and thigh (16.3%). Conclusion: This study found that PNIs occurred most frequently in the lower limbs, compared with the upper limbs, among earthquake victims with CLIs. Lower limb PNIs mainly occurred in the peroneal nerve, while upper limb PNIs mainly occurred in the radial nerve.
