Advances in acetabular reconstruction in revision total hip arthroplasty: maximizing function and outcomes after treatment of periacetabular osteolysis around the well-fixed shell.

摘要

As the numbers of primary and revision hip arthroplasties increase, a comprehensive approach to acetabular revision is needed. A substantial number of patients with radiographic osteolysis in the hip after a total hip arthroplasty have a well-fixed acetabular shell. The purpose of this paper was to describe the classification and treatment of these patients, including the exposure of the acetabular component with a retained, well-functioning femoral component; access to osteolytic lesions; bone-grafting; liner fixation; and when to make the decision to remove the well-fixed acetabular shell.
