Review Comparative Study
Cemented versus uncemented hemiarthroplasty for hip fractures: a systematic review of randomised controlled trials.
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. ⋯ 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.

Case Reports
Severe anaphylactic reaction to chlorhexidine during total hip arthroplasty surgery. A case report.
Two consecutive hip surgery procedures in the same patient were aborted following a severe anaphylactic reaction of the patient. After the second procedure, the patient was diagnosed to be allergic to chlorhexidine, a component of the gel used to insert a urinary catheter. Chlorhexidine allergy is rare, and the delayed presentation may make it easy to overlook. In hip arthroplasty surgery, this may result in an abandoned procedure and the need for re-operation.

Preoperative psychological distress has been reported to predict poor outcome and patient dissatisfaction after total hip arthroplasty (THA). The purpose of this study was to investigate if pre-operative psychological distress was associated with adverse functional outcome after primary THR. We analysed the database of a prospective multi-centre study undertaken between January 1999 and January 2002. ⋯ There was a substantial improvement in mental distress in patients who reported mental distress prior to surgery. The results suggest that pre-operative psychological distress did not adversely compromise functional outcome gain after THA. Despite having worse absolute values both pre and post operatively, patients with mental distress did not have any less functional gain from THA as measured by improvement in OHS.

Acetabular impaction grafting has been shown to be very effective, but concerns regarding its suitability for larger defects have been highlighted. We report the use of this technique in a large cohort of patients, and address possible limitations of the technique. ⋯ In our series, results were disappointing where a large rim mesh or significant reconstruction was required. In light of these results, our technique has changed in that we now use predominantly larger chips of purely cancellous bone, 8-10 mm3 in size, to fill the cavity and larger diameter cups to better fill the aperture of the reconstructed acetabulum. In addition we now make greater use of i) implants made of a highly porous in-growth surface to constrain allograft chips and ii) bulk allografts combined with cages and morcellised chips in cases with very large segmental and cavitary defects.
