Cemented versus Uncemented Hemiarthroplasty for Hip Fractures: A Systematic Review of Randomised Controlled TrialsAzegami S, Gurusamy KS, Parker MJ.
We performed a systematic review of randomised controlled trials in order to identify the best available evidence to compare the outcome between cemented and uncemented hemiarthroplasty for treatment of intracapsular hip fractures.
We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, MEDLINE and the National Research Register (UK) to retrieve all of the published randomised controlled trials designed to address these issues, in order to perform a meta-analysis.
Eight studies involving 1169 patients were determined to be appropriate for meta-analysis. The following statistically significant differences were found between the cemented and uncemented prostheses: (1) longer operative time for cemented prosthesis; (2) lower reduction in mobility score for those treated with cemented prosthesis; (3) fewer patients with residual pain in the hip and lower pain score (signifying less pain) for those treated with a cemented prosthesis.
Our meta-analysis has shown that there is good evidence that the use of cement during hemiarthroplasty will reduce the amount of residual hip pain and also allow better restoration of function. There is no evidence of significant adverse effects of cement on mortality or other complications encountered. These observations apply to older designs, and there is a need for randomised trials comparing hydroxyapatite-coated modern stems with cemented prostheses.
