Summary
Custom acetabular components offer a solution for severe bone loss in revision total hip arthroplasty (THA). CT-based planning and custom implants provide stable fixation and improved hip biomechanics in complex cases.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Radiology
Background:
- Severe acetabular bone loss, especially Paprosky type IIIA defects, presents a significant challenge in revision total hip arthroplasty (THA).
- Standard implants often lack the necessary stability and fixation for these complex cases.
- Custom-made acetabular components, utilizing computed tomography (CT)-based three-dimensional (3D) planning, offer a tailored solution.
