BACKGROUND: Numerous types of arthroplasties may be used in the surgical treatment of a @entity173 ( @entity3330 ). The main differences between the implants are the design of the stems, whether the stem is fixed in place with or without cement, whether a second @entity7687 joint is included within the prosthesis ( @entity162 ) or whether the whole hip joint is replaced. OBJECTIVES: To review all randomised trials that have compared different arthroplasties for the treatment of @entity173 in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised register. Additional trials were identified by searching reference lists of relevant articles, conference proceedings, and contact with trialists. Date of most recent search: January 2001. SELECTION CRITERIA: All randomised and quasi-randomised trials comparing different arthroplasties (and or cement), for the treatment of @entity173 . DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality, by use of a ten-item checklist and extracted data. MAIN RESULTS: Thirteen trials involving 1464 @entity1 were included. One trial investigated two comparisons. Cemented prostheses, when compared with uncemented (four trials, 391 @entity1 ) were associated with a lower risk of failure to regain mobility (relative risk (RR) 0.60, 95% confidence interval (CI) 0.44, 0.82) and of post-operation @entity158 at a year or later (RR 0.51, 95% CI 0.31, 0.81). For this comparison, there were no significant differences in any other outcome. @entity308 with @entity162 (six trials, 742 @entity1 ) showed no significant differences between the two types of implant. Two trials of 269 @entity1 compared different types of hemiarthroplasty with a total hip replacement and two trials of 151 @entity1 compared either different types of prosthesis head or different bipolar prostheses. Because of the limited number of cases and the use of different prostheses, no definite conclusions could be made from these four studies. REVIEWER'S CONCLUSIONS: Cementing prostheses in place seems to reduce @entity158 post-operatively and results in better mobility, but because of the under-reporting of outcomes and the small number of @entity1 involved, no definite conclusions can be made. The role of bipolar prostheses and total hip replacement is uncertain. Further well-conducted randomised trials are required.
