Cemented hemiarthroplasty for neck of femur fractures has been advocated over uncemented hemiarthroplasty due to better post-operative recovery and patient satisfaction. However, studies have shown adverse effects of bone cement on the cardio-respiratory system which may lead to higher morbidity and mortality. Therefore, in some institutes, the use of an uncemented prosthesis has been adopted for patients with a high number of co-morbidities. The aim was to compare early mortality rates for cemented vs. uncemented hemiarthroplasties. Cohort study of displaced intracapsular hip fractures treated with hemiarthroplasty between 1999–2009 at one institute. A total of 3094 hemiarthroplasties performed; out of which 1002(32.4%) were cemented and 2092(67.6%) were uncemented. 48hour and 30day mortality rates for the two groups were compared and a multivariate Cox regression model used to eliminate confounding factors. Significant confounding factor included age, sex, mini mental test score, medical co-morbidities, Nottingham Hip Fracture Score and delay to surgery.Introduction
