Dislocation of Bipolar Hip Hemiarthroplasty in the Elderly: Comparison of the Posterolateral and Anterolateral Approaches

Keywords: Hip prosthesis, hip dislocation, femoral neck fracture, elderly

Abstract

Objective: To compare the risk of bipolar hip hemiarthroplasty dislocation after femoral neck fracture using the posterolateral versus the anterolateral approach. Materials and Methods: Patients older than 60 years who underwent bipolar hip hemiarthroplasty for femoral neck fracture between 2021 and 2022 were included. The number of dislocations following the posterolateral or anterolateral approach was recorded. Results: Seventy-nine cases were included: 46 (58.8%) were treated with the posterolateral approach and 33 (41.8%) with the anterolateral approach. There were 3 dislocations in the posterolateral group and 2 in the anterolateral group; no significant differences were found (p = 0.655). Conclusions: There were no differences in the risk of bipolar hemiarthroplasty dislocation between the posterolateral and anterolateral approaches in the treatment of femoral neck fractures in the elderly.
