[Optimal timing of operations to treat fractures of the femoral neck with endoprotheses :  CRP as a parameter of postoperative immunologic reaction].
BACKGROUND
The optimal time to perform endoprosthesis of hip fractures in the elderly is still under discussion. CRP as an objective marker of postoperative inflammatory reaction should give an indication if early or late surgery is favored.


METHODS
CRP values from 122 patients with no complications after hip arthroplasty of femoral neck fractures were analyzed in context with the time between the trauma and the operation.


RESULTS
In early surgery within 24 h after trauma the CRP values were significantly lower than in delayed surgery.


CONCLUSIONS
The lower postoperative inflammatory reaction after early surgery of hip fractures provides a better outcome when treated with arthroplasty.
