Objectives: Aim of the current study was the differentiation of patient selection for THA and HA after femoral neck fractures in Germany by the data analysis of the German national register for arthroplasty "Endoprothesenregister Deutschland" (EPRD) and analysis of risk factors.

Methods: Anonymized data from 2014 to 2021 were provided by the EPRD. Inclusion criteria were patients with femoral neck fractures. Data were analysed with focus on technique i.e. hemiarthroplasty (HA) versus total hip arthroplasty (THA) and subgroups dual mobility versus common THA. Data were analysed with focus on BMI, Elixhauser comorbidity factor, hospital experience and weekday vs. holiday/weekend of surgery. Data were analysed with univariate and multivariate statistical analysis.

Results and conclusion: Preliminary results from the analysis showed a number 51938 patients. 72% women and 28% men. The median age was 82±9 years. Two third (66%) of implants were HA and 33% were THA. The majority of 88% HA were performed in a cemented technique, the majority of THA with 70% were performed in a cementless technique. In only 1.3% (n=689) a dual mobility implant was used. The overall failure probability was 3.7% in HA and 5.6% in THA. The mean BMI was 24.8 ±4.2kg/m² and the Elixhauser-Score showed a mean of 7.4±7.6 points. The revision rate was 4.3% after arthroplasty for femoral neck fractures. Surprisingly, the highest rate of revision with 5.6% was seen in hospitals with a high case load of arthroplasties of more than 500/year.

The current data analysis of EPRD is the first cumulative analysis of patients with femoral neck fracture and arthroplasty over a time period of 7 years. The common used technique for arthroplasty in Germany is a cemented hemiarthroplasty in these elderly patients. A dual mobility option is scarcely used. The revision rate of the arthroplasty is not dependent on the hospital case load. The risk factor analysis of comorbidities is in progress.
