Study DesignRetrospective cohort study.ObjectiveThe aim of this study was to assess the incidence and trends of the spine fracture hospitalization and surgery in Finland in 1998-2017.Summary Of Background DataTraumatic spine fractures are rare, yet they are known to cause significant long-term disability and therefore social, functional, and financial burden. The incidence of spine fractures and related mortality has been suggested to have declined during recent years. However, there are no population-based studies investigating the incidence of surgical treatment of spine fractures.MethodsThe data for this study was obtained from the Finnish nationwide National Hospital Discharge Register. The study population covered all patients 20 years of age or over in Finland during a 20-year period from January 1, 1998 to December 31, 2017.ResultsA total of 54,612 patients were hospitalized for a spine fracture in Finland in 1998-2017, and 7138 (13%) of the patients underwent surgery. The annual population-based incidence of spine fracture hospitalization increased 57% during the 20-year period, from 57 per 100,000 person-years to 89 per 100,000 person-years. In addition, the incidence of spine fracture surgery increased 65%, from 5.3 per 100,000 person-years to 8.8 per 100,000 person-years. The incidence of cervical spine fracture surgery tripled, and thoracic spine surgery doubled from 1998 to 2017, while incidence of lumbar fracture surgery declined by 13%. Among patients 60 years of age or older, the incidence of cervical spine fracture surgery increased 400%.ConclusionIncidences of cervical, thoracic, and lumbar fracture hospitalizations increased constantly in Finland during 1998-2017. Accordingly, incidence of cervical and thoracic spine fracture surgery increased rapidly, whereas the incidence of lumbar fracture surgery even decreased, during this 20-year period.Level Of Evidence3.
