Abstract
PURPOSE: For femoral neck fractures, recent scientific evidence supports cemented hemiarthroplasty (HA) over uncemented HA and suggests that total hip arthroplasty (THA) should be performed more frequently. We report the current surgical trends in treating femoral neck fractures in Finland. METHODS: The study was conducted using the Finnish National Hospital Discharge Register and included all Finns at least 50 years of age who underwent surgery for femoral neck fractures from 1998 through 2011. Age- and sex-specific incidence rates and annual proportion of each treatment method were calculated. RESULTS: During 1998-2011, a total of 49,514 operations for femoral neck fracture were performed in Finland. The proportion of uncemented HA increased from 8.1% in 2005 to 22.2% in 2011. During the same time, the proportion of cemented HA decreased from 63.9 to 52.5%, internal fixation decreased from 23.2 to 16.1% and THA increased from 4.9 to 9.2%. CONCLUSIONS: Between 2005 and 2011, the proportion of uncemented HA for femoral neck fractures increased markedly in Finland, while cemented HA and internal fixation declined. During this time, the use of THA nearly doubled. The current evidence-based guidelines for treatment of femoral neck fractures were mainly followed, but the increase in uncemented HA procedures contradicts recent scientific evidence.
