Scholarcy highlights

  • Paget’s disease of bone is a localised chronic osteopathy characterised by an osteoclastic dysfunction with increased resorption and subsequent compensatory formation of new woven bone with an anarchic microstructure
  • We retrospectively reviewed 39 total hip arthroplasties with acetabular and/or femoral cementless hydroxyapatite fully-coated components
  • Thirty-nine uncemented hydroxyapatite fully-coated total hip arthroplasty were implanted in patients with PDB of the hip
  • PDB exclusively involved the acetabulum in 31 hips, exclusively involved the femur in two hips, and both acetabulum and femur were involved in six hips
  • At the latest follow-up, we report 84% excellent or good clinical outcome using the Harris hip score
  • Of the 37 uncemented acetabular components implanted into pagetic bone, three presented with radiolucent lines at the latest follow-up
  • The short- to mid-term outcome of uncemented total hip arthroplasty in patients with hip osteoarthritis secondary to Paget’s disease of bone was satisfactory
