INTRODUCTION: Fixation-related complications of displaced @entity2249 treated by internal fixation are accompanied by high mortality and morbidity. The aim of this study is to investigate the pre- and postoperative radiographic @entity174 characteristics in relation to @entity1 age and the occurrence of reoperation caused by fixation @entity177 . METHODS: The preoperative radiographs of all @entity1 presenting with a proximal femur @entity174 between January 2004 and December 2012 were retrospectively assessed for @entity174 (AP and lateral view). @entity1 with a displaced @entity2249 treated by closed reduction and internal fixation were included. The postoperative radiographs were assessed on adequate @entity174 reduction and correct position of the implant. @entity1 characteristics and outcome in terms of occurrence of fixation @entity177 (implant breakout, non-union) and reoperation rate were recorded. RESULTS: Hundred and-forty-nine @entity1 were admitted with a displaced @entity2249 and treated by internal fixation. Fixation @entity177 was seen in 34 (23  %) @entity1 ; 9 @entity1 suffered from @entity2530 . In total, 37 (25  %) @entity1 underwent reoperation caused by fixation-related complications. Taking the different age categories into account, 44  % of the @entity1  >75  years suffered fixation @entity177 compared with 17  % of the @entity1  <65  years. Postoperative incorrect reduction, with persisting @entity3029 and/or lack of medial support resulted in reoperation in 37  % of the @entity1 , compared to 19  % reoperations in @entity1 with adequate reduction. CONCLUSION: The results of this study show that @entity1 age and @entity174 reduction are important predictors for reoperation. In the preoperative treatment plan, @entity1 age should be taken into account and surgeons should strive for anatomical reduction. @entity1 over 75 should always undergo arthroplasty. In @entity1 aged 65-75, conversion to arthroplasty should be strongly considered if anatomical reduction is impossible.
