An Image-Based Tool To Examine Joint Congruency At The Elbow, Emily A. Lalone
Electronic Thesis and Dissertation Repository
Post-traumatic osteoarthritis commonly occurs as a result of a traumatic event to the articulation. Although the majority of this type of arthritis is preventable, the sequence and mechanism of the interaction between joint injury and the development of osteoarthritis (OA) is not well understood. It is hypothesized that alterations to the joint alignment can cause excessive and damaging wear to the cartilage surfaces resulting in OA. The lack of understanding of both the cause and progression of OA has contributed to the slow development of interventions which can modify the course of the disease. Currently, there have been no reported …

A number of commercially available radial head (RH) implants are used for the management of RH fractures. The optimal shape of a RH implant to restore joint mechanics to the native state has not been established. This work compares radiocapitellar contact and kinematics for three implant designs as well as the native RH. These implants include an axisymmetric, a quasi-anatomic and a patient-specific design. When compared to the native RH, only the axisymmetric implant was significantly different in contact area (p=0.008). Active and passive forearm supination was assessed for differences in translations of the RH. Significant differences were found in …
