Late Disassembly of a Modular Acetabular Component of a Total Hip Replacement
|
|
|
|
|
Abstract
|
|
|
lar designs of hip prosthesis have been popular recently. But, the presence of a nonfixed interface between the plastic cup and the metal backing imtroduced the additional possibility of postoperative separation of the polyethylene cup from the
metal
backing, which may be rare cause of irreducible dislocation of the hip. Disassembly of metal-backed modular acetabular components used for total hip arthroplasty is becoming more common. These cases have occurred early in the postoperative period
and
have been usually associated with dislocation of the femoral component. We report another case of disassembly of a modular acetabular component, which occurred four years after surgery and was not associated with dislocation of the femoral
component.
