A dynamic elbow flexion simulator for cadaveric testing of UCL injury and reconstruction

Ulnar Collateral Ligament (UCL) injuries among overhead throwing athletes are an increasing epidemic. The most common and successful treatment for this injury is reconstruction surgery. Success of UCL reconstruction is only measured in the short-term and little is known about the long-term consequences. No research has been conducted to analyze the effectiveness of reconstruction while accounting for the forces of relevant muscles during dynamic testing. The goal of this project was to design and fabricate a dynamic elbow flexion simulator for cadaveric testing. A biomechanical study was then conducted using the custom apparatus to further investigate potential long-term effects of UCL reconstruction.
