“…Building on prior dynamic finite element analysis of RSA [46,47,48], the goal of this study was to investigate the effects of glenoid lateralization and liner design on shoulder stability for a new implant system from Zimmer Biomet. Other additions to the modeling approach were the inclusion of superior elements of the scapula (the acromion and coronoid process) along with the introduction of an explicit deltoid muscle structure.…”

“…The humeral bone, scapula, and deltoid were also edited in Geomagic to provide smoother surface geometries that were free of any holes or anomalous features. The deltoid anatomy was approximated by more simplified basic geometry, as had previously been done for the subscapularis and infraspinatus [47,48]. The glenosphere and humeral components were virtually inserted following manufacturer-recommended guidelines and checked by a surgeon (Fig.19) [63].…”

possible without Vijay Permeswaran who not only set the groundwork that this research was built upon, but was a great mentor, teacher, and help especially when I was just starting out at the lab. Dr. Brendon Patterson also played a pivotal role, acquiring the Zimmer system used during testing as well as offering his time to provide critical medical insight towards the shoulderimplant system. I'd also like to thank past and present members of the University of Iowa Orthopedic Biomechanics lab that I had the pleasure of working with. Specifically, I'd like to give a shout out to Steven Long and Keven Dibbern for helping with diagnostics, as well as introducing me to several techniques used in my thesis. I'd like to acknowledge Dr. Jess Goetz, and Dr. Carolyn Hettrich, members of the previous shoulder team, for offering valuable perspectives and insight about the subject. Lastly, I would like to thank my friends and family for supporting me, specifically my mother for her feedback throughout the writing process, my dad for his life advice, and my grandparents for their encouragement.
