Labral tears in the shoulder joint is a common injury experienced by over 4 million patients annually, limiting motion and causing pain. The objective of this MQP was to estimate the stresses developed during the formation of labral tears for a variety of conditions including range of motion and patient variables using ANSYS and SolidWorks. The resulting data could be used to 3D print the shoulder joint with defects for visualization. The loads at the point of tear initiation were determined for various motions including abduction, adduction, and flexion. A threshold is observed above 100N where a tear can propagate predominantly under abduction. An understanding of tear forces can enable surgeons to determine the appropriate treatment for the tear.
