The Acetabular Component in Revision THA
With acetabular revision in a failed total hip arthroplasty, the goal is to maximize support for the revision cup on intact host bone. In most cases, this can be accomplished with a large, uncemented cup and cancellous graft.
But sometimes, there is so much acetabular bone loss that adequate fixation with a hemispherical cup is impossible. This occurs with:
- Irregular defects
- Major bone deficiency
- Poor bone stock
- Fractures or non-unions
- Irradiated bone
In those cases, augments and cages may be used as modular adjuncts to the hemispherical cup.
At the Philadelphia Revision Course, we caught up with William L. Griffin, MD, and Wayne G. Paprosky, MD, and asked them how they prefer to handle acetabular component revision. Click on the images below to hear their comments.
