Background: Cementless total hip replacement is the common THR performed in England, Wales, Northern Irelandand the Isle of Man. The Corail stem is the most popular cementless implant and has a ODEP 10A rating. Review ofits performance in the registry identified an increase rate of revision amongst the smaller stem sizes. However, claritywas not provided on the explanation for this finding. We ...

BACKGROUND Due to the adverse effects of cemented hip arthroplasty, uncemented stems with hydroxyapatite (HA) coating reduces these risks and enhanced integration. The concept of an extensive HA coating for the fixation of a tapered femoral stem (Corail®) was introduced, which can achieve durable biological fixation and preserve normal periprosthetic bone activity. Here we describe the clinical...

BACKGROUND Today, dislocated femoral neck fractures are commonly treated with a cemented hip arthroplasty. However, cementing of the femoral component may lead to adverse effects and even death. Uncemented stems may lower these risks and hydroxyapatite (HA) coating may enhance integration, but prosthetic stability and clinical outcome in patients with osteoporotic bone have not been fully explo...

Intraoperative proximal femoral fracture, one of the most common complications of total hip arthroplasty (THA), occurs more often in cementless procedures and can affect rehabilitation, hospitalization time, and cost of treatment. The goal of this study was to identify risk factors for intraoperative proximal femoral fracture in THA to identify high-risk groups preoperatively and minimize the i...

The Norwegian Arthroplasty Register recorded 24,408 primary total hip replacements from 1987 to 1993; 2907 of them (13%) were performed with uncemented femoral components. We have compared the results of eight different designs, each used in more than 100 patients. Survivorship of the components was estimated by the Kaplan-Meier method using revision for aseptic loosening of the femoral compone...

Primary uncemented femoral stems reported to the Norwegian arthroplasty register between 1987 and 2005 were included in this prospective observational study. There were 11 516 hips (9679 patients) and 14 different designs of stem. Kaplan-Meier survival probabilities and Cox regression were used to analyse the data. With aseptic loosening as the end-point, all currently used designs performed ex...
