Demographic data, American Society of Anesthesiologists (ASA) classification, type of surgery, complications, and reoperation rate were obtained from patient records. The functional outcome was assessed by the modified Harris-Hip Score (mHHS), general health using the EQ-5D, and radiological outcome by Beals &amp; Tower (B&amp;T) criteria.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 129 patients with a mean age of 79\u00a0years (range 43\u2013102) were included. 70% of all patients were female and 68% of the patients had an ASA score\u2009\u2265\u20093. 20 patients suffered from a Vancouver A, 90 from a Vancouver B and 19 from a Vancouver C fracture. 14% of the patients died within the first 2\u00a0years after surgery. The reoperation rate after open reduction and internal fixation (ORIF) (<jats:italic>n<\/jats:italic>\u2009=\u200960) was 8% and after revision arthroplasty (RA) (<jats:italic>n<\/jats:italic>\u2009=\u200947) 30% (OR 3.4, 95% CI [1.21\u201310.2]).
