Intertrochanteric fractures are common in older age group. But still many patients suffer from high morbidity and mortality and decreased ambulation levels, because of accompanying general weak- ness and various senile diseases. From January 1991 to February 1995, we treated 46 patients older than 65 years with intertrochanteric fractures of femur. A retrospective study was performed to determine which Pre- and postinjury factors were predictive of mortality and ambulatory capacity 1 year after operation. Potential causative factors included age, gender, prefracture ambulatory ability, postoperative ambulatory ability, associated medical problem, fracture type, degree of osteoporosis, American. Society of Anesthesiologists rating of operative risk, interval between injury and operatiorl. This retrospective study were analyEed with following results ; 1. Mortality was releated to prefracture ambulatory ability, postoperative ambulatory ability, ASA risk, interval between injury and operation, which were statistically significant. 2. Eighteen(39%) patients maintained their prerfacture ambulatory ability at a poslinjury 1 year ; Twenty-eight(61%) patients lost some degree of ambulatory ability.
