What Factors Drive Taper Corrosion?

What Factors Drive Credit Risk

Credit risk remains the most significant risk facing financial institutions. An understanding of the drivers of credit risk (i.e. the possibility that a borrower will fail to repay a loan) is therefore a key analytical and practical challenge for lenders. Furthermore, to the extent that on a number of occasions in the past, banking system problems have been largely associated with simultaneous ...

Mechanically assisted taper corrosion in modular TKA.

The purpose of this study was to characterize the prevalence of taper damage in modular TKA components. One hundred ninety-eight modular components were revised after 3.9±4.2 years of implantation. Modular components were evaluated for fretting corrosion using a semi-quantitative 4-point scoring system. Design features and patient information were assessed as predictors of fretting corrosion da...

Head-Neck Taper Corrosion in Hip Arthroplasty

Modularity at the head-neck junction of the femoral component in THA became popular as a design feature with advantages of decreasing implant inventory and allowing adjustment of leg length, offset, and soft tissue balancing through different head options. The introduction of a new modular interface to femoral stems that were previously monoblock, or nonmodular, comes with the potential for cor...

Utilizing Magnesium Corrosion to Drive Dexamethasone Release

INTRODUCTION Traumatic brain injuries (TBI) are a major cause of death and disability worldwide, especially in children and young adults. In the United States, the mortality rate is estimated to be 21% thirty days after a TBI [1]. Brain trauma occurs as a result of focal impact upon the head, which produces alterations in cerebral blood flow and pressure within the skull. These changes lead to ...
