Randomized Controlled Trial Comparative Study
Randomised trial of blood transfusion versus a restrictive transfusion policy after hip fracture surgery.
Debate exists as to what should be the transfusion threshold for patients with anaemia after hip fracture surgery. ⋯ This study confirms other recent research studies which found that reducing the transfusion threshold to 8.0gdl(-1) appears to be a safe practice for this group of patients.

Randomized Controlled Trial Comparative Study
Periprosthetic bone loss following hemiarthroplasty: a comparison between cemented and cementless hip prosthesis.
The aim of this prospective randomized clinical study was to evaluate the magnitude of bone mineral changes as well as the clinical results after cemented and cementless haemiarthroplasty (HA) for femoral neck fracture. The study was comprised of 60 patients (mean age 85.2 years); 30 of them underwent cemented HA and 30 cementless HA. All patients underwent osteodensitometry for the purpose of Bone Mineral Density (BMD) evaluation. ⋯ We noted a trend of less intensive BMD reduction in all Gruen zones in group A compared to group B. However, the difference in BMD reduction between these two groups was significant only in zones 2, 3 and 4. Our results support the view that cemented hemiarthroplasty should be used for the management of displaced femoral neck fractures providing better functional outcomes and lower periprosthetic bone loss.

Randomized Controlled Trial
Periarticular raft constructs and fracture stability in split-depression tibial plateau fractures.
To evaluate relative fracture stability yielded by screws placed above a lateral plate, as well as locking and non-locking screws placed through a plate in a split depression tibia plateau fracture model. ⋯ Designs utilising screws through the plate trended towards statistically significant improved stability against plateau displacement relative to utilising screws outside the plate. Our study also suggests that there is no significant benefit of locking screws over non-locking screws in this unicondylar tibia plateau fracture model.

Randomized Controlled Trial Comparative Study
The potential of implant augmentation in the treatment of osteoporotic distal femur fractures: a biomechanical study.
Osteoporotic fractures of the distal femur are an underestimated and increasing problem in trauma and orthopaedic surgery. Therefore, this study investigates the biomechanical potential of implant augmentation in the treatment of these fractures. ⋯ This study shows a promising potential of implant augmentation in the treatment of osteoporotic distal femur fractures.

Randomized Controlled Trial Multicenter Study Comparative Study
Re-displacement of stable distal both-bone forearm fractures in children: a randomised controlled multicentre trial.
Displaced metaphyseal both-bone fractures of the distal forearm are generally reduced and stabilised by an above-elbow cast (AEC) with or without additional pinning. The purpose of this study was to find out if re-displacement of a reduced stable metaphyseal both-bone fracture of the distal forearm in a child could be prevented by stabilisation with Kirschner wires. ⋯ Pinning of apparent stable both-bone fractures of the distal forearm in children might reduce fracture re-displacement. The frequently seen complications of pinning might be reduced by a proper surgical technique.
