Periprosthetic fracture of the acetabulum during total hip arthroplasty in a patient with Paget's disease

Abstract

The case of a patient with Paget's disease of the pelvis (acetabulum) who had an intraoperative posterior wall fracture during the insertion of a noncemented acetabular component into an under-reamed acetabular bed of sclerotic Pagetoid bone is reported. This unusual complication has not, to my knowledge, been previously reported. Patients with sclerotic bone, like those with osteoporotic bone, may also be at risk for periprosthetic acetabular fractures when an under-reaming technique is used.
