Some screws in these racks may undergo several cycles of autoclave sterilization before they are used in a patient. This study aims to determine if these repeated cycles negatively affect the mechanical properties, specifically the torque to fracture, of the screws. A literature review investigating the effects of sterilization on titanium and stainless-steel screws indicated that there was no effect on the torque to fracture however these studies had limitations. The most common limitations were small sample size and limited number of sterilization cycles. After the literature review, preliminary studies were conducted to determine appropriate testing parameters for the present studies. These included determining how much axial force to apply and if consistent results could be obtained. The largest issue discovered was the mode of failure being stripping of the screwhead instead of fracture at the head-neck junction as seen in the clinic. The methods for this study were then finalized along with other possible experiments to further our knowledge in this field. These included taking SEM images of the surface and inserting the screw by hand if the mode of failure continued to be stripping of the screwhead. Knowledge gained from these studies can be applied in the clinic to ensure screws used in orthopedic surgery are not mechanically compromised due to their sterilization procedure. 2020 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1595416853674582 http://rave.ohiolink.edu/etdc/view?acc_num=osu1595416853674582 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
