Uncemented total hip arthroplasty in Paget's disease of the hip: a report of 5 cases with 5-year follow-up.

摘要

Five patients with Paget's disease localized to the acetabulum received cementless acetabular components during total hip replacement. Three were primary surgeries, and 2 were revisions of a failed cemented acetabular component. At an average of 5.8 years (range, 4.8-8.8 years) after the operation, all acetabular components were well fixed radiographically with no migration or loosening. No patients complained of clinical symptoms referable to the acetabular component. No revisions had been performed. The ability of this inherently abnormal bone to proceed through the reparative and remodeling phases of porous ingrowth adds support to the use of uncemented components for acetabular reconstruction in Paget's disease of the hip.
