Radiological findings of February 2023 twin earthquakes-related spine injuries.

Background: The February 6, 2023, twin earthquakes in Türkiye caused significant structural damage and a high number of injuries, particularly affecting the spine, which underscores the importance of understanding the distribution and nature of vertebral injuries in disaster victims.

Aim: To investigate the distribution of radiological findings of vertebral injuries in patients referred to a major tertiary center during the February 6, 2023 twin earthquakes in Türkiye.

Methods: With the approval of the institutional ethics committee, 1216 examinations of 238 patients transferred from the region to a tertiary major hospital after the twin earthquakes of February 6, 2023, were retrospectively analyzed for spine injuries.

Results: Spine computed tomography (CT) scans were performed in 192 of 238 patients with a suspected spinal injury, 42 of whom also had an magnetic resonance imaging (MRI). In 86 of 192 patients (44.79%; M:F = 33:53) a spinal fracture was detected on CT and in 33 of 42 patients (78.57%; M:F = 20:13) a spinal injury was found on MRI. Of the 86 patients in whom vertebral injury was detected, fractures were detected in the Denis-B group in 33, Denis-C in 4, Denis-D in 20 and Denis-E in 11 patients. Among the vertebral bodies: 40 "compression fractures", 17 "burst fractures", 5 "translational dislocation fractures", 5 "flexion-distraction fractures" and 58 "prolonged forced fetal posture fractures" were detected. In addition, isolated transverse or spinous process fractures were found in eighteen vertebrae.

Conclusion: Our study highlights the prevalence and diverse spectrum of spinal injuries following the February 6, 2023 twin earthquakes in Turkey underscoring the urgent need for effective management strategies in similar disaster scenarios, and emphasizing the "prolonged forced fetal posture" damage we encountered in earthquake victims who remained under the collapse for a long time.
