Intertrochanteric hip fracture surgery in Chinese: risk factors for predicting mortality.

Surgery is the preferred treatment for intertrochanteric fractures. This study aimed to analyze risk factors for predicting mortality after intertrochanteric hip fracture surgery by arthroplasty and internal fixation. We performed a retrospective analysis of 1,263 patients who received surgical treatment for intertrochanteric fractures from January 2005 to December 2010. The clinical and follow-up data from 491 eligible patients were collected and analyzed. The age, activity before surgery, activity after surgery, anesthesia, medical illness, and the time between fracture and surgery were significantly associated with the mortality as single factor. Multifactor analysis showed that the activity after surgery, medical illness, and the time between fracture and surgery were correlated with postoperative mortality. In conclusion, these data suggest that the age, activity after surgery, medical illness could affect postoperative mortality of patients of intertrochanteric fractures. These factors may be used to predict the postoperative mortality of intertrochanteric fractures.
