Epidemiology of pediatric thoracolumbar spinal fractures and associated injuries: a single-center experience

This retrospective study aimed to investigate the epidemiology of pediatric patients with thoracolumbar spinal fractures and the characteristics of associated injuries.

Sixty-one patients under 18 years old with thoracolumbar spinal fractures were included in the study. Patients were divided into two groups: ≤ 8 years (Group 1) (n = 13) and > 8 years (Group 2) (n = 43). Patients were analyzed for age, gender, fracture type, fracture level, etiology, and associated injuries.

The mean age was 158.7 (± 53.1) months, and the male/female ratio was 1.26. The most common fracture etiology was motor vehicle accidents (39.4%) and falls from height (18%). There was no correlation between the fracture type, the number of fractured vertebrae, and age. The most common associated injury was orthopedic injuries (34.3%). In Group 2, associated injuries developed more frequently in the presence of a major fracture, whereas in Group 1, associated injuries could occur even in isolated minor fractures. In Group 1, intrathoracic injuries associated with fractures (36.4%) were significantly higher than in Group 2 (4.2%). Surgical intervention was required in 9.8% of patients.

Although thoracolumbar spinal fractures are rare in children, they are essential because preventable accidents essentially cause them and can have devastating consequences. There are significant differences in epidemiologic and clinical features between age groups. In this study, we have shown that even minor thoracolumbar vertebral fractures may be accompanied by associated injuries in children under 8 years of age. In contrast, major fractures are more frequently related to other organ injuries in older children. This may be because more severe trauma is required for a fracture of the thoracolumbar spine, which is more flexible and elastic in young children compared to adolescents. Our study has provided current and essential results regarding the etiology of pediatric thoracolumbar spine fractures. More multicenter studies are needed to understand the characteristics of thoracolumbar fractures in pediatric patients.
