Systematic reviews disagree, but some recent studies have shown better function and less pain after operation with bipolar hemiarthroplasty compared to fixation by two screws in elderly patients operated for displaced femoral neck fractures. There is still uncertainty regarding the mortality associated with both procedures. To investigate mortality and the risk factors for death among patients with displaced femoral neck fractures within the first three years after surgery, comparing operation with bipolar hemiarthroplasty (HA) and internal fixation (IF) by two screws.Background
Aim of the study
A well conducted randomised study found similar functional results for patients with displaced femoral neck fracture comparing operation with a modern uncemented bipolar hemiarthroplasty with a cemented bipolar hemiarthroplasty. The mortality associated with the two procedures has not been sufficiently investigated. To investigate the mortality and the risk factors for death among patients with displaced femoral neck fractures the first year after surgery, comparing operation with modern uncemented and cemented bipolar hemiarthroplasty (HA).Background
Aim of study
Infection after total hip arthroplasty is a severe complication. Controversies still exist as to the use of cemented or uncemented implants in the revision of infected THAs. Based on the data in the Norwegian Arthroplasty Register (NAR) we have studied this topic. During the period 2002–2008 45.724 primary THAs were reported to NAR. Out of these 459 were revised due to infection (1,0%). The survival of the revisions with uncemented prostheses were compared to revisions with cemented prostheses with antibiotic loaded cement and to cemented prostheses with plain cement. Only prostheses with the same fixation both in acetabulum and in femur were included in the study. Cox-estimated survival and relative revision risks were calculated with adjustments for differences among groups in gender, type of surgical procedure, type of prosthesis, and age at revision.Introduction
