    Abstract:
    In this article, we examine rates of in-hospital mortality of elderly patients with femoral neck fracture treated with internal fixation or hemiarthroplasty. Data were analyzed for 51,003 patients (> or = 65 years old) admitted with femoral neck fractures to New York state hospitals between 1985 and 1996. The primary outcome examined was in-hospital mortality. Associations between type of surgical procedure and outcome were assessed using a multiple logistic regression model, adjusting for patient age, sex, race, number of comorbidities, and residence in a nursing facility before hip fracture. Approximately 30% of the study group had undergone open or closed reduction and internal fixation; the other 70% had undergone hemiarthroplasty. Forty-six percent of the internal fixation group and 56% of the hemiarthroplasty group were 85 years old or older (P < .001). Median hospital stays were 13 days for the internal fixation group and 15 days for the hemiarthroplasty group (P < 001). In-hospital mortality was 5.1% overall, 3.9% for the internal fixation group, and 5.6% for the hemiarthroplasty group (P < .001). The association between type of procedure and mortality held after adjusting for patient age, sex, and number of comorbidities (odds ratio, 1.42; 95% confidence interval, 1.29-1.56; P < .001). After controlling for potential confounding variables, we found that elderly patients who had undergone hemiarthroplasty after femoral neck fracture were more likely to die during hospitalization than those who had undergone internal fixation.
