Short-term results after total hip arthroplasty using dual-mobility acetabular cup on geriatric patients with femoral neck fracture

Abstract

The rate of femoral neck fractures (FNF) increases exponentially with age, meanwhile in geriatric patients they are associated with high levels of functional deficiency and mortality. Studies find that hip arthroplasty is a method of choice for treatment of displaced FNF. One option regarding the increased risk of postoperative dislocation in these patients is the dual-mobility acetabular cup (DMAC). The aim of our study is to assess the functional outcome, joint stability and complication rate after total hip arthroplasty (THA) using DMAC in geriatric patients with FNF. In the study were included 390 patients with a mean follow-up period of 31.2 months. No cases of dislocation or intraprosthetic dislocation were encountered. Displaced FNF can successfully be treated with THA using DMAC, as it provides excellent stability and function, as well as low risk of revision surgery.
