Shoulder Joint Replacements

When shoulders become arthritic the joint surfaces may be replaced by prosthetic components. The arthritis is often secondary to shoulder deficiencies such as rotator cuff damage. A successful replacement must restore shoulder function for the activities of daily living and be strong enough to withstand the forces acting at the joint to avoid component failure or loosening. In this project, we will examine two design concepts currently used for shoulder replacements and determine the design trade-offs between function and the resultant forces on the fixation surfaces. We will use parameter studies to explore design changes that improve function without increasing the risk of loosening.
