There is good evidence that cementing the prostheses in place will reduce post-operative pain and lead to better mobility. From the trials to date there is no evidence of any difference in outcome between bipolar and unipolar prosthesis. There is some evidence that a total hip replacement leads to better functional outcome than a hemiarthroplasty. Further well-conducted randomised trials are required.
Moore hemi-arthroplasty with and without bone cement in femoral neck fractures. A clinical controlled trial.
In a clinical, controlled trial 112 patients with fresh femoral neck fractures were allocated to two groups of treatment: 55 patients had a Moore hemi-arthroplasty cemented with methyl methacrylate and 57 patients a non-cemented prosthesis. 75 patients attended the follow-up study. At 6 weeks, 3 months, 6 months and 12 months after the operation the function of the hip was assessed according to Merle d'Aubigné. At 6 weeks, 3 months and 6 months after the operation the clinical results were significantly better among patients with cemented prosthesis, especially in relation to pain relief and gait function. It is concluded that fixation of the prosthesis with cement improves the clinical results, at least during the first 6 months following the operation.
