High-speed x-ray fluoroscopy for the evaluation of dynamic shoulder function in vivo

Project description

Osteoarthritis (OA) is the primary condition leading to total joint replacement surgery of the shoulder. Abnormal joint loading plays a major role in the degenerative process of OA, and has been attributed to shoulder trauma, age-related muscle-tendon pathology including rotator cuff tears, and neuromuscular impairment such as stroke. Muscle forces contribute substantially to joint contact forces; however, the roles of the shoulder muscles in generating loads at the glenohumeral joint are not well understood. This is because there is no method available for measuring muscle forces non-invasively. The aim of this project will be to develop an accurate three-dimensional deformable finite-element model of the human shoulder to calculate the contact pressures and stresses produced at the glenohumeral joint during activities of daily living. By combining subject-specific motion data (bi-plane x-ray fluoroscopy and optical motion capture data) with medical imaging (Magnetic Resonance Imaging) and computational modelling, joint-contact mechanics will be non-invasively quantified in vivo.
