Hip arthroplasty in Paget
Area of Science:
- Orthopedic Surgery
- Bone Metabolism
Background:
- Paget's disease of bone affects bone remodeling.
- Coxarthrosis is a common complication of Paget's disease.
Purpose of the Study:
- To review hip arthroplasty outcomes in patients with Paget's disease.
Main Methods:
- Retrospective review of 5 hip arthroplasties.
- Implanted between 1997 and 2000.
- Patients had coxarthrosis secondary to Paget's disease.
Main Results:
- Sclerotic, vascularized pagetic bone increased surgical time and blood loss.
- No complications were observed.
- 100% good clinical results.
Conclusions:
- Hip arthroplasty is effective for coxarthrosis in Paget's disease.
- Surgical challenges include bone quality and bleeding.
- Radiographic varus alignment occurred in 2 cases.
Abstract:
A total of 5 hip arthroplasties implanted between 1997 and 2000 in 5 patients affected with coxarthrosis secondary to Paget's disease were reviewed. The quality of the pagetic bone (sclerotic and very vascularized) resulted in a slightly longer amount of time required for surgery because of the difficulty preparing prosthetic placement and intra- and postoperative blood loss exceeding the norm. Complications were not observed. Clinical results were good in 100% of cases. Radiographically, 2 stems were assembled in varus.
