Evaluation of a shared decision-making strategy with online decision aids in surgical and orthopaedic practice: study protocol for the E-valuAID, a multicentre study with a stepped-wedge design.

Background: Inguinal hernia repair, gallbladder removal, and knee- and hip replacements are the most commonly performed surgical procedures, but all are subject to practice variation and variable patient-reported outcomes. Shared decision-making (SDM) has the potential to reduce surgery rates and increase patient satisfaction. This study aims to evaluate the effectiveness of an SDM strategy with online decision aids for surgical and orthopaedic practice in terms of impact on surgery rates, patient-reported outcomes, and cost-effectiveness.

The distribution of probability values in medical abstracts: an observational study.

Background: A relatively high incidence of p values immediately below 0.05 (such as 0.047 or 0.

Effects of anticoagulants on outcome of femoral neck fracture surgery.

Purpose: To review records of 330 patients who underwent surgery for femoral neck fractures with or without preoperative anticoagulation therapy.

Methods: Medical records of 235 women and 95 men aged 48 to 103 years (mean, 81.6; standard deviation [SD], 13.

Can larger-bodied cemented femoral components reduce periprosthetic fractures? A biomechanical study.

Introduction: The risk for late periprosthetic femoral fractures is higher in patients treated for a neck of femur fracture compared to osteoarthritis. It has been hypothesised that osteopaenia and consequent decreased stiffness of the proximal femur are responsible for this. We investigated whether a femoral component with a bigger body would increase the torque to failure in a biaxially loaded composite Sawbone model.

Hospital mortality after arthroplasty using a cemented stem for displaced femoral neck fractures.

Purpose: To review hospital mortality after hemiarthroplasty or total hip arthroplasty (THA) using a cemented stem for displaced femoral neck fractures.

Methods: Medical records of 284 hips in 70 men and 209 women aged 45 to 106 (mean, 81.3) years who underwent hemiarthroplasty (n=232) or THA (n=52) with a cemented stem using third-generation cementing techniques (including use of a plug, lavage, and cement pressurisation) for displaced femoral neck fractures were retrospectively reviewed.

Periprosthetic fracture torque for short versus standard cemented hip stems: an experimental in vitro study.

In an attempt to preserve proximal femoral bone stock and achieve a better fit in smaller femora, especially in the Asian population, several new shorter stem designs have become available. We investigated the torque to periprosthetic femoral fracture of the Exeter short stem compared with the conventional length Exeter stem in a Sawbone model. Forty-two stems; 21 shorter and 21 conventional stems both with three different offsets were cemented in a composite Sawbone model and torqued to fracture.

Improving maximum flexion with a posterior cruciate retaining total knee arthroplasty: a fluoroscopic study.

Achieving a large range of motion (ROM) is a much-desired clinical outcome after total knee arthroplasty (TKA), especially in Asian and Middle Eastern cultures. TKA design plays an important role in providing the post-operative ROM. This study investigated the kinematics of a new high-flexion posterior cruciate ligament retaining total knee replacement, featuring an enlarged posterior condylar offset and a more conforming tibiofemoral articulation.
