Although there is little doubt that arthroplasty of one form or another is appropriate treatment for many patients with a displaced femoral neck fracture, there is ongoing controversy about the relative merits of different types of arthroplasty among specific groups of patients. In particular, total hip arthroplasty is infrequently recommended because of concerns about the perceived high initial cost, increased risk of dislocation, and the anticipated low functional demands and life expectancy of the typical hip fracture patient. When viewed in this traditional context, the merits of total hip arthroplasty are not believed to outweigh the risks, except in the rare instance of a patient with preexisting symptomatic hip arthritis that sustains a hip fracture. ⋯ Finally, recent advances in the design of THA components such as the introduction of improved bearing surfaces allowing the use of larger femoral heads, combined with improved surgical techniques, may be making THA safer and less prone to dislocation and other mechanical complications. The purpose of this paper is to review the recent literature regarding the results of total hip replacement in patients with a displaced fracture of the femoral neck. Total hip replacement may have a larger role in the treatment of displaced femoral neck fractures than it has in the past.

Hip fractures are a significant cause of morbidity and mortality worldwide and the burden of disability associated with hip fractures globally vindicate the need for high-quality research to advance the care of patients with hip fractures. Historically, large, multi-centre randomized controlled trials have been rare in the orthopaedic trauma literature. Similar to other medical specialties, orthopaedic research is currently undergoing a paradigm shift from single centre initiatives to larger collaborative groups. ⋯ To resolve this controversy large multi-national collaborative randomized controlled trials are required. In 2005, the International Hip Fracture Research Collaborative was officially established following funding from the Canadian Institute of Health Research International Opportunity Program with the mandate of resolving controversies in hip fracture management. This manuscript will describe the need, the information, the organization, and the accomplishments to date of the International Hip Fracture Research Collaborative.

Meta Analysis Comparative Study
Gamma nails revisited: gamma nails versus compression hip screws in the management of intertrochanteric fractures of the hip: a meta-analysis.
Concerns about the Gamma nail have largely been fueled by early randomized trials and meta-analyses suggesting an increased risk of subsequent femoral shaft fractures when compared with compression hip screws. Whereas meta-analyses favor compression hip screws over first-generation Gamma nails, little is known as to whether the newer Gamma nail designs and the improved learning curve associated with the implants have reduced the risk of femoral shaft fracture. The current meta-analysis aimed to explore the effects of time and Gamma Nail design on the risks of femoral shaft fracture after treatment of extracapsular hip fractures. ⋯ Our meta-analysis of randomized trials suggests that previous concerns about increased femoral shaft fracture risk with Gamma nails have been resolved with improved implant design and improved learning curves with the device. Earlier meta-analyses and randomized trials should be interpreted with caution in light of more recent evidence.

Meta Analysis Comparative Study
Minimally invasive hip fracture surgery: are outcomes better?
Intertrochanteric hip fractures have high morbidity and mortality rates. The purpose of this study was to determine if minimally invasive plating, nailing, or external fixation operations lead to improved outcomes for intertrochanteric hip fractures compared with standard insertion of a sliding hip screw (SHS). ⋯ Although a significant heterogeneity exists between pooled studies, minimally invasive hip fracture plating, nailing, or external fixation was associated with a decrease in transfusion rate [relative risk of 0.63 as compared to standard SHS (95% confidence interval 0.41 to 0.96; I(2) = 83.6%)]. There was no significant difference for the other comparisons, including mortality between minimally invasive plating, nailing, or external fixation and standard insertion of an SHS.

Nonunion of fractures about the femoral neck and intertrochanteric hip regions is uncommon. Patients who develop nonunions of these fractures typically exhibit marked pain and disability, thereby presenting a treatment challenge to the orthopaedic surgeon. Factors that guide the choice of salvage treatment include the anatomic site of the nonunion, the quality of the remaining proximal bone and articular surface, and patient factors (such as age and activity level). ⋯ The challenges involved in planning to convert to hip arthroplasty include the need for acetabular resurfacing, selecting the femoral implant, and managing discontinuity of the greater trochanter. Furthermore, there are additional technical challenges that may be encountered, such as broken hardware, deformity, and femoral bone defects. Overall, salvage of nonunions of femoral neck and intertrochanteric hip fractures in properly selected patients can provide patients with good to excellent results.
