Randomized Controlled Trial Comparative Study
Outcome of short proximal femoral nail antirotation and dynamic hip screw for fixation of unstable trochanteric fractures. A randomised prospective comparative trial.
A prospective, randomised, controlled trial was performed to compare the outcome of treatment of unstable trochanteric fractures with either a short proximal femoral nail antirotation (PFNA) or dynamic hip screw (DHS). Eighty one patients with unstable fracture of the proximal part of the femur were randomised, at the time of admission, for fixation with either a short PFNA (n=42) or DHS (n= 39). The primary outcome measure was reoperation within the first postoperative year and mortality at the end of one year. ⋯ Patients treated with a PFNA experienced a shorter fluoroscopy time and less blood loss. Six patients in DHS group had implant failure while none experienced this in PFNA group. The PFNA group had a better functional outcome than the DHS group.

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.
