[Effect of hip fracture at different sites in elderly patients on prognosis].

OBJECTIVE

To determine the effect of site of fracture on the prognosis for patients of elderly hip fracture.

METHODS

From January 2012 to December 2014, 667 patients with hip fractures were divided into femoral neck fracture group and intertrochanteric fracture group according to the site of fracture. There were 304 cases of intertrochanteric fracture, including 96 males and 208 females, with an average age of (80.33±7.94) years old. There were 217 cases of femoral neck fracture, including 74 males and 143 females, with an average age of (79.82±9.33) years old. Patients' data, mortality and activities of daily living were compared between two groups.

RESULTS

There were no significant differences in age, gender, comorbidity, ASA classification, and anesthesia between two groups, but the time of admission to surgery, duration of operation, blood loss of intra-operative, volume of drainage, and the average of transfusion were shown to have significant differences. The levels of White blood cell count (WBC) for intertrochanteric fracture group were shown to be higher than that of femoral neck fracture patients at admission, 1, 3 and 5 days after operation. The levels of hemoglobin, and albumin for intertrochanteric fracture were lower than that of femoral neck fracture patients at all period of time. The mortality of intertrochanteric fracture group during hospitalization, 1, 3, 6, and 12 months were higher than that of femoral neck fracture, but did not reach significant difference. In patients who survived, the scores of ADL for femoral neck fracture were higher than that of intertrochanteric fracture at discharge, 1, 3 months after operation, but there was no significant difference for ADL at 6 and 12 months between two groups.

CONCLUSIONS

The response of stress for intertrochanteric fracture were more than femoral neck fracture, but the mortality was similar than that of femoral neck fracture after excluding the influence of age, sex, comorbidity, and other factors. Compared to intertrochanteric fracture, the femoral neck fracture patients had a better functional recovery during early stage, and the two groups reached a similar functional recovery at 1 year after operation.
