Poster #M195 THE INTERACTION BETWEEN CNR1 GENETIC VARIATION AND CANNABIS EXPOSURE PREDICTS PREFRONTAL FUNCTIONAL CONNECTIVITY AND BEHAVIOR DURING WORKING MEMORY

The tapered joints of modular hip implants are prone to fretting and crevice-corrosion. This can lead to total failure in under a year, especially for heavier, more active implant recipients. In this study, fractography of a failed Profemur Z implant showed that a life limiting fatigue crack was nucleated on the anterolateral surface of the implant's neck. The fatigue crack nucleation area appeared to have both more fretting damage and a higher corrosion rate than on other surfaces of the neck.
