Incidence of adult traumatic spinal cord injury in Saint Petersburg, Russia

Abstract

Study design: Retrospective population-based cohort study. Objectives: To characterise the epidemiology of traumatic spinal cord injury (TSCI) among the inhabitants of Saint Petersburg, Russia. Setting: All hospitals in Saint Petersburg. Methods: Charts for all individuals admitted to city hospitals from 1st January 1 2012 to 31st December 2016 with acute TSCI were reviewed. Incidence rates were calculated for the whole period and for each year separately. Gender-specific and age-specific incidence rates were calculated, and epidemiological characteristics and possible risk factors were analysed. Results: A total of 361 people were identified. The average annual incidence rate was 17.6 per million, varying from 21.2 (2013) to 13.6 (2016), and 70.9% were men. Mean age at injury was 42.1 years. Injuries from falls represented 49.8% of cases, and motor vehicle accidents 18.9%. The male:female ratio in the low-falls group was 1.2:1, and among the elderly patients, it was 0.5:1. Lesions at the cervical level were involved in 49.3%, thoracic in 24.7%, and lumbar/sacral in 23.5%. TSCI was complete in 16.9%. Concomitant injuries occurred in 47.2% of cases, and traumatic brain injuries in 37.7%. Conclusion: TSCI incidence decreased during the observation period and was 2.4 times more common among men than women. In half of the cases, injuries involved the cervical level, and a fall was the most frequent injury cause. Elderly women more often had falls from a low height than men. Multiple injuries—most frequently traumatic brain injuries—were common.
