Revision Total Hip Arthroplasty Using a Custom Monoflange Acetabular Component for Severe Bone Loss and Pelvic Discontinuity Due to Acetabular Component Loosening: A Case Report

Year: 2024

Type: article

Abstract: Revision total hip arthroplasty using custom monoflange acetabular components (CMACs) in cases of severe bone loss is becoming an increasingly preferred alternative to traditional implants, which may not provide stable fixation in such cases. However, this procedure also carries a higher risk of infection and implant loosening. This case report discusses a 67-year-old female patient who presented with old acetabular component loosening and significant pelvic bone loss. A 3D model of the pelvis was created based on computed tomography, enabling the design of a personalized monoflange acetabular component. The revision surgery was performed using a posterolateral approach, and the implant was successfully secured. After six months, the patient reported no complications or pain. It seems that CMACs offer a promising alternative for patients presenting with chronic implant loosening and severe bone stock loss.
