Abstract
BACKGROUND: Spinal fractures are a group of complex injuries whose management varies according to a number of factors. The aim of this study was to analyze trends in the management of spinal fracture surgery in Sweden from 2008 to 2023 with a focus on disparities based on gender, surgery method, age and geographical location. A secondary aim was to predict future incidence of spinal fracture surgeries. METHODS: Comprehensive open source data was obtained from the Swedish National Board of Health and Welfare. The data was stratified based on gender, surgery method, age and geographical location per year and analyzed for trends. Future trends were projected using regression modeling. The student's T-test was used to compare means. RESULTS: The incidence of spinal fracture surgery decreased overall from 2008 to 2023 while maintaining an increased incidence for males compared to females. The highest incidence for osteosynthesis was 2.7 per 100 000 inhabitants in 2008 and 1 in 2023. This trend is projected to be reversed in 2030. Several surgery methods have decreased in usage and are projected to reach close to 0 in 2030. The patient group that underwent spinal fracture surgery had a higher mean age in 2023 compared to 2008. The incidence of spinal fracture surgery varied significantly across Sweden where region Östergötland performed 6.3 surgeries per 100 000 inhabitants and region Örebro performed 1.4. CONCLUSIONS: We found several trends where males may undergo spinal fractures surgery more commonly than females. Probable influencing factors may be increased life-spans and osteoporosis. This may also explain the observed shift towards older age groups in spinal fracture surgery. The decreased use of several surgery methods may reflect changes in operational techniques, demographics, and more standardized care. Geographical disparities may indicate different local health care protocols and uneven healthcare utilization and access. TRIAL REGISTRATION: Not applicable.
