Cemented Versus Uncemented Stems in Total Hip Arthroplasty in Patients With Femoral Neck Fractures

The purpose of this prospective randomized study is to compare the quality of treatment between cemented versus uncemented hydroxyapatite coated femoral stems in Total Hip Arthroplasty (THA) in patients who suffers from dislocated femoral neck fractures. Our hypothesis is that an uncemented option spares the patient the operative load of the cementing procedure, i e risk of fatty embolism and inflammatory response, which in turn also perhaps reduces the postoperative cognition strain and improves mobilization parameters. If the uncemented option has the same excellent fixation in poor bone stock, as in the case of these osteopenic fractures, and also has the same good clinical outcome, it would be a viable standard option for the treatment of dislocated femoral neck fractures.
