BackgroundWe show a comparison between two patient groups of the inpatient population suffering from femoral neck fractures registered in the external quality assurance between 1993 and 1997 and between 2005 and 2009.ResultsThe comparison between two patient groups showed the following developments: an increase in patient numbers per year from 4,229 to 5,842 where the average age remained constant but the proportion of elderly patients over 70 years old increased; the period of hospitalization was clearly shorter (from 27 days to 18 days); an increase in comorbidities (according to the ASA classification) with simultaneous decrease of the complication rate (from 11.1% to 7.6%). The inhospital mortality remained constant at 5.3%. At the same time the number of hospitals which treat patients with femoral neck fractures decreased from 166 to 150. Concurrently the number of patients per hospital and year increased from 23.6 to 41.3 cases.ConclusionThe technique of operative treatment changed and while during the 1990s many patients with femoral neck fractures were treated by implanting a total endoprosthesis, in the 2000s treatment was dominated by the hemi prosthesis. During the two periods of study use of the osteosynthesis technique decreased. In conclusion, the study showed an obvious compression of performance in trauma surgery but despite everything there was a clear improvement of treatment quality with respect to complication rates.
