- Original description
The general purpose of this study is to examine whether the dual mobility cup (Novae® Serf) reduces the number of hip dislocations after total hip replacement, both early dislocation (≤1 year) and late dislocation (>1 year) after primary THR compared with a conventional cup design (Trabecular MetalTM Modular Acetabular System).Read full original descriptionShow less
Risk of Dislocation After Total Hip Replacement: Dual Mobility Cup vs. Unipolar Cup. A Randomized Controlled Trial With Patients ≥65 Years Operated for Hip Osteoarthritis With Primary Total Hip Replacement (THR).
The general purpose of this study is to examine whether the dual mobility cup (Novae® Serf) reduces the number of hip dislocations after total hip replacement, both early dislocation (≤1 year) and late dislocation (>1 year) after primary THR compared with a conventional cup design (Trabecular MetalTM Modular Acetabular System).
Inclusion: Patients with hip arthritis who are amenable to surgery with THR and age ≥ 65 years referred to the Department of Orthopedic Surgery at either Section Farsø, Frederikshavn Hospital or Aalborg University Hospital. Patients who are willing to participate in the trial and who give their written, informed consent after receiving oral and written information.
Exclusion: Earlier hip bone surgery (excluding arthroscopic surgery); Elective bilateral surgery; Sequelae of Calvé-Legg-Perthes' disease, caput necrosis, epiphysiolysis; Patients who do not wish to participate; Proximal femoral or acetabular fracture; Hip dysplasia with subluxation Crowe types III and IV; If the patient's bone morphology is unsuitable for a cemented Exeter® femoral stem; Patients with no e-mail.
