OBJECTIVETo evaluate the effect of surgical timing of intertrochanteric fracture on 1-year postoperative mortality in elderly and analyze factors that influence 1-year postoperative mortality.

METHODSA retrospective search had been conducted to analyze 350 patients of intertrochanteric fracture from December 2012 to December 2014. The studied patients were divided into three groups such as the group of <72 h and the group of 72-96 h and the group of >96 h, which depended on the time of injury to surgery. The postoperative mortality was compared among the groups and causes of death in patients were evaluated after surgery. Multiple logistic regression was then used to distinguish independent effects on mortality.

RESULTSThe one-year postoperative mortality of three groups(<72h, 72-96 h, >96 h)were significantly different and the rate of death was 1.8%, 8.1%, 10.3%. The one-year postoperative mortality of the group of <72 h was inferior to the group of 72-96 h and >96 h respectively(<0.05). Age, preoperative coexist disease and surgical timing were dependent risk factors to one-year postoperative mortality(<0.05, OR>1).

CONCLUSIONSThe early surgery can diminish one year postoperative mortality, the patient who is older and has too many preoperative coexist diseases and is delayed to surgery has higher risk to die in one year after surgery.
