Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures
Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Effect of the colony microstructure on transport critical current of high-J{sub c} Tl-1223 thick films
High J{sub c}, polycrystalline, TlBa{sub 2}Ca{sub 2}Cu{sub 3}O{sub 8+x} thick films on poly-YSZ substrates were examined by x-ray microdiffraction, electron microscopy, and electron backscatter diffraction. The superconducting phase was formed by vapor phase thallination. X-ray phi scans were used to study the local and macroscopic in-plane texture. Electron backscatter kikuchi diffraction was used to discern the grains structure within the colonies. Figure shows results of a limiting path calculation of J{sub c} vs colony mosaic
