The influence of bone cement and American Society of Anesthesiologists (ASA) class on cardiovascular status during bipolar hemiarthroplasty for displaced femoral-neck fracture: A multicenter, prospective, case-control study.

This study indicate a similar hemodynamic change intraoperatively between ≤ASA II patients and ≥ASA III patients in the cemented group, and between patients with cemented and cementless hemiarthroplasty in the ≥ASA III patients. With modern hemiarthroplasty techniques, bone cement might be as safe as cementless techniques in elderly, ≥ASA III patients.Level of evidence III, multi-center case control cohort study.
