| Popis: | Background The aim of this study is to investigate the population and primary total hip arthroplasty (THA)-based incidences, fracture types, complications, and survival of operatively treated periprosthetic femoral fracture (PFF). Methods This retrospective study reviewed 202 cases of operatively treated PFFs in a study period from January 2004 to December 2016. The Vancouver classification was used to classify PFFs. Results The incidence of PFF related to 1000 primary THAs per year was 2.7 (standard deviation 1.0, range 0.9-4.5) at a defined hospital district area during the study period. The mean population-based incidence of operatively treated PFFs raised from 1.6 to 4.5 per 100,000 person-years during the study period. The B1-type fracture was the most common fracture type in 71 of 202 (35%) of these PFFs. The cumulative incidence of re-revision was 10.9% at 1 year and 15.6% at 15 years (95% confidence interval [CI] 10.9-21.0). The cumulative incidence for other major complications was 6.4% at 1 year and 9.9% at 15 years (95% CI 5.9-15.0). The cumulative incidence of death after PFF was 7.4% at 1 year and 56.3% at 15 years (95% CI 41.3-68.8) during the follow-up time from January 1, 2004 to December 31, 2019. Conclusion This country-specific study showed a 3-fold increasing trend in the incidence of operatively treated PFFs from 2004 to 2016 per 1000 THAs. The Vancouver type B1 fracture was the most common type. A high number of complications were associated with PFFs and 7.4% of the patients had died within 1 year after PFF surgery. |
