The concurrent bilateral stress fractures of the femoral neck (SFFN) are extremely rare injuries in individuals without excessive bone activities. We present a case with compression type stress fracture in the right femoral neck, and displaced type stress fracture in the left femoral neck which might progress from an undiagnosed tension type fracture. Based on the findings of the literature rev...

The following is a summary of the recommendations in the AAOS’ clinical practice guideline, The Diagnosis of Periprosthetic Joint Infections of the Hip and Knee. This summary does not contain rationales that explain how and why these recommendations were developed nor does it contain the evidence supporting these recommendations. All readers of this summary are strongly encouraged to consult th...

A mix-mode cohesive fracture model considering tension, compression and shear material behaviour is presented, which has wide applications to geotechnical problems. The model considers both elastic and inelastic displacements. Inelastic displacement comprises fracture and plastic displacements. The norm of inelastic displacement is used to control the fracture behaviour. Meantime, a failure fun...

BACKGROUND AND PURPOSE Patients with fracture of the proximal femur often undergo blood transfusion. A pneumatic compression bandage has been shown to reduce transfusion after primary hip arthroplasty for osteoarthritis. In this randomized trial, we evaluated the efficacy of this bandage following surgery for hip fracture. PATIENTS AND METHODS 288 patients, 50 years or older with 292 fracture...

Title: Crack Growth During Brittle Fracture in Compression. Author: Bartlett W. Paulding, Jr. Submitted to the Department of Geology and Geophysics February 9, 1965 in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the Massachusetts Institute of Technology. Photoelastic analysis of several two-crack arrays predicts that compressive fracture is initiated at cra...

PURPOSE To compare the efficacy of quadratus femoris muscle pedicle bone flap transplantation combined with hollow compression screw fixation versus AO hollow compression screw fixation in the treatment of femoral neck fracture for Chinese young and middle-aged patients. METHODS Case-controlled studies (CCTs) were used to compare the two operative methods in the treatment of femoral neck frac...

Background: A variety of treatment modalities are available for fracture of distal radius. However, there is a lack of consensus on the preferred treatment in these cases. Aims: To compare the different methods for the treatment fracture of distal part of the radius based on the outcome at the end of treatment. Methods: Analysis of cases with fracture of distal radius treated at our centre over...

PURPOSE Biomechanical comparison of straight DCP and helical plates for fixation of transversal and oblique tibial bone fractures were analyzed and compared to each other by axial compression, bending and torsion tests. METHOD An in vitro osteosynthesis of transverse (TF) and oblique bone fracture (OF) fixations have been analysed on fresh sheep tibias by using the DCP and helical compression...
