Sunilkumar PD, Oh KJ, Cho HW, et al. - The present research was performed to assess surgical complications of monolithic dual mobility cup total hip arthroplasty (THA) in elderly patients with fractured neck of the femur. Researchers prospectively included a total of 97 patients (97 hips) with displaced femoral neck fractures who gave informed consent for participation. This study collected data of all patients who had undergone THA with monolithic dual mobility cup and computed tomography scans to assess radiographic parameters including anteversion, inclination, and loosening of acetabular cups, and periprosthetic acetabular fractures. Although the dual mobility cup lowered the risk of early dislocation after THA, it was reported that the use of the monolithic dual mobility was associated with improper cup fixation and periprosthetic acetabular fractures in the elderly with poor bone stock.
