Multi-Modality Experimental Approach in Orthopedic Biomechanics with Clinical and Device Applications

Abstract

Orthopedic biomechanics is the field of study wherein the principles of mechanics are applied to biological problems in the characterization, evaluation, and repair of the musculoskeletal system. Repair methods, such as orthopedic devices and surgical interventions, are often evaluated through in vitro mechanical testing. Because of the complex loading environment in the human body, relevant tests can be difficult to design. In light of these challenges, the present work surveys three biomechanical experiments developed and performed with clinical orthopedic surgical practice or device development. First, a novel double tension slide technique for surgical repair of distal bicep tendon rupture is mechanically evaluated. Second, a novel method is developed for mechanically evaluating cranial defect repair in small animals with direct application for a novel shape memory polymer repair device. Third, novel femoral broach designs are mechanically evaluated for cutting efficiency with application in improved femoral subsidence for total hip replacement patients.
