- Abstract:
- Background: Among several treatment options for femoral neck fractures, one that has been increasingly favorable in the recent history, is the implantation of total hip arthroplasty (THA) (1,2). There have been differences in opinion on the ideal treatment. The question whether internal fixation (IF), hemiarthroplasty (HA) or THA represent the best treatment for this diagnosis, has been discussed in several studies. The main part of this thesis consists of a systematic review of all recent literature on THA and HA treating femoral neck fractures. Evaluating these and calculating an overall revision rate was the primary aim. Secondly, the thesis aimed to calculate the incidence rates for THA after femoral neck fractures of eight different countries in the year 2017. Methods This thesis was commenced, by rigorously reviewing all clinical studies between 1999 and 2019 that contained information on revision numbers. Since different studies vary greatly in follow-up time, a standard evaluation system for revision rates had to be applied. Revisions per 100 component years was the calculation of choice. For the assessment of primary THA for femoral neck fractures per inhabitant, numbers of national arthroplasty registers and official statistical data information have been used. Results The percental projection of the revision rate at 10 years was 11.8% for primary THA after femoral neck fracture. For HA following the same diagnosis the revision rate was 24.6% at 10 years. The eight register reports that were reviewed revealed an incidence rate for THA after femoral neck fractures of an average of 9.7 per 100,000 inhabitants. Conclusion These results show that THA for femoral neck fractures has superiority over HA for femoral neck fractures in terms of revision probability at 10 years. Incidence rates for THA for this particular diagnosis were similar among the reviewed countries. The registry data listed in this thesis, could be used for an international comparison of THA numbers.
