Development Of A Crosslinked Osteochondral Xenograft And A Collagen Stabilizing Intra-Articular Injection To Remediate Cartilage Focal Lesions To Prevent Osteoarthritis, Mark Lewis Mosher
Development Of A Crosslinked Osteochondral Xenograft And A Collagen Stabilizing Intra-Articular Injection To Remediate Cartilage Focal Lesions To Prevent Osteoarthritis, Mark Lewis Mosher
Theses and Dissertations
Osteoarthritis is one of the most common causes of disability in adults in America. It is a progressive and degenerative disease where the articular cartilage is broken down and lost from the surfaces of bones causing chronic pain and swelling in the joints, and currently has no cure. The most commonly osteoarthritis starts from a focal lesion on the cartilage surface, which will expand on the surface and downwards through the thickness of the tissue. The current gold standard for correcting cartilage focal lesions is the osteochondral autograft/allograft transplantation (OAT), which replaces the defect with a fresh osteochondral graft. The …
Ex Vivo Biomechanical Comparison Of A Novel Compression Screw Fastener And Traditional Ao Cortical Bone Screw For Fixation Of A Simulated Slab Fracture In The Equine Third Carpal Bone, Allison Salinger
Theses and Dissertations
Frontal plane slab fractures account for the majority of third carpal bone (C3) fractures in performance horses. Treatment is stabilization with an AO cortical screw. Complications are fragment splitting, fragment spinning, and irritation of dorsal soft tissue structures. A novel, headless, cannulated screw with interlocking threads (the Headless Compression Screw Fastener, HCSF) has been developed to resist multidirectional forces. Simulated C3 slab fractures were created in nine paired equine carpi. HCSF or AO cortical screws were loaded in shear to failure. Stiffness, maximum load to failure, and yield load was assessed in linear mixed models. No significant difference was detected …
