The initial idea for this thesis grew out of a workshop con ducted for divorced parents by the Group for Quality Parent-Child Relationships at Ohio State University. To those parents experiencing divorce and to the group itself, I express my gratitude. In addi tion, there are several individuals to whom I would like to give my deepest appreciation. Dr. Andrew Schwebel and Dr. John Moreland were of invaluable assistance throughout the project and without their continual help the study would not have been completed. The statis tical analysis phase of the study was completed in large part through the efforts of Dwayne Ball, whose great patience, expertise, and support were of great value. The study was greatly facilitated by my roommate, close friend, and collaborator Jim Vess, who com pleted his thesis along with my own, and whose daily support and presence were constantly reassuring. While the contributions of the previously mentioned individuals have been during the last two years, my parents, Burril and Marilynn, have provided me with the opportunity and the support needed to benefit from my educational experiences throughout my life. To them and to my brothers, Paul and David, and my sister Anita, I cannot express my appreciation. Finally, and by no means least, my love for my fiancee Eve and her unending caring and support have given each of us the drive to achieve whatever we have been able to, including this thesis. iii

Background Polyethylene liner dissociation is a rare but catastrophic event in total hip arthroplasty (THA), and certain implant designs are known to be at greater risk. Although the DePuy Pinnacle (Warsaw, IN, USA) modular acetabular construct has an excellent record of fixation and wear, an unexpectedly high number of liner dissociations has been noted.
