What Are the Determinants of Mortality After Cemented Bipolar Hemiarthroplasty for Unstable Intertrochanteric Fractures in Elderly Patients?

摘要

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.
