Hip Osteo Arthritis Clinical Trial
Official title:
Bone Metabolism Adjacent to Hip Prosthetic Surfaces. A Randomized Clinical F-PET/CT Study.
What is the intensity of F-PET uptake adjacent to four analyzed hip endoprosthetic components and in healthy femur and acetabulum, 1, 4 and 9 months after surgery?
A clinical study of 32 patients, age 50-69 years, healthy unless osteoarthritis in one hip,
randomized in two groups (16 each) plus a reference group of same 32 patient´s contralateral
healthy hip.
Intervention will be surgery with a total hip arthroplasty. The four studied endoprosthetic
components are:
- Cemented Exeter stem (Stryker Warsaw, USA) with a ceramic 32 mm head and Palacose cement
with gentamycin, applied with 3:rd generation cementation technique.
- Uncemented Lubinus SP-CL stem (Waldemar Link, Hamburg, Germany) with a ceramic 32 mm
head.
- Uncemented Delta PF cup (Limacorporate spa, Udine, Italy).
- Uncemented fibrous metal Delta TT cup (Limacorporate spa, Udine, Italy). Both cups will
have cross linked Ultra-high-molecular-weight polyethylene (UHWMP).
Clinical score, radiography and uptake of Fluoride tracer will be analyzed.
