Flow diverter devices are small stents used to divert blood flow away from aneurysms in the brain, stagnating flow and inducing intra-aneurysmal thrombosis which in time will prevent aneurysm rupture. Current devices are formed from thin (∼25 μm) wires which will remain in place long after the aneurysm has been mitigated. As their continued presence could lead to secondary complications, an absorbable flow diverter which dissolves into the body after aneurysm occlusion is desirable. The absorbable metals investigated to date struggle to achieve the necessary combination of strength, elasticity, corrosion rate, fragmentation resistance, radiopacity, and biocompatibility. This work proposes and …

Analysis Of Healthy Glenohumeral Arthrokinematics And Anatomic Shoulder Implant Subluxation Using 4dct, Kylie Kiera Paliani
Electronic Thesis and Dissertation Repository
The shoulder is the most mobile joint in the human body, with the glenohumeral joint specifically allowing a wide range of motion and a high incidence of instability due to its ability to translate, as well as rotate in its socket. However, the extent of translation in a healthy glenohumeral joint is not well-established. Additionally, it is unclear if subluxation correction after anatomic total shoulder arthroplasty (TSA) with posterior augmented glenoid (PAG) implants remains consistent throughout active motion. This thesis aimed to evaluate healthy glenohumeral arthrokinematics to benchmark normal joint proximity and translation, and to assess if a TSA with …
The Role Of Transverse Plane Malalignment In Posterolateral Corner Complex Injury, Larissa M. Madia
The Role Of Transverse Plane Malalignment In Posterolateral Corner Complex Injury, Larissa M. Madia
Electronic Thesis and Dissertation Repository
The posterolateral corner (PLC) is a complex of ligaments and soft tissues in the knee that primarily constrain external tibial rotation. Neglecting PLC injury is a contributing factor in graft failure following cruciate ligament reconstruction. This emphasizes the importance of understanding PLC injury mechanisms, considering their disposition to multi-ligament tears. The PLC can be damaged by hyperextension. Tibial torsion, a twisting of the tibia longitudinally relative to the femur, offsets the transverse knee alignment, consequently altering the loading of soft tissues. Therefore, the objective of this investigation was to determine if tibial torsion affects loading of PLC components during hyperextension, …
