Abstract
BACKGROUND: Primary hemiarthroplasty is proposed for the treatment of unstable intertrochanteric fractures in elderly patients with the advantages of early mobilization, acceptable functional results, and lower failure rates. The 1-year mortality rates demonstrated high variance in the literature, whereas, the factors related to 1-year mortality were not widely investigated. The main purpose of the present study was to determine predictive factors related to 1-year mortality after primary cemented calcar-replacement bipolar hemiarthroplasty performed for unstable intertrochanteric fracture. METHODS: One hundred six patients with the mean age of 80.7 years were included in this retrospective study. Age, gender, body mass index, comorbid diseases, American Society of Anesthesiologists score, total hospitalization time, time from injury to surgery, operation time, estimated blood loss, postoperative mobilization time, and decrease in Koval ambulatory categories were evaluated. Univariate and multivariate analyses were performed to determine major predictors of 1-year mortality. The Kaplan-Meier survival analysis was used to construct the cumulative survival rate. RESULTS: Three or more American Society of Anesthesiologists scores, presence of ≥3 comorbid diseases, and postoperative mobilization time of ≥2 days were significantly correlated with 1-year mortality. Presence of ≥3 comorbid systemic diseases was identified as the major predictive factor for 1-year mortality. The overall 5-year cumulative survival rate was 5.6%. CONCLUSION: Having three or more comorbid systemic diseases has been detected as the major determinant of 1-year mortality after primary cemented calcar-replacement bipolar hemiarthroplasty performed for unstable intertrochanteric fracture in elderly patients.
