Presence of either a Hill Sachs or a Bony Bankart lesion has been indicated as a possible cause of subluxation and anterior shoulder dislocation. Previous studies have investigated only effects of these isolated lesions on the glenohumeral instability of the shoulder. The purpose of this thesis was to investigate the effect of both Bony Bankart lesion and Hill-Sachs lesion in the glenohumeral joint on the stability of the shoulder. We hypothesize that as the size of the lesion increases, the glenohumeral joint’s stability will decrease. We further hypothesize that the presence of both defects together will reduce the glenohumeral joint’s stability to an even greater extent. Finite element analysis approach was utilized to model the glenohumeral joint in combination with the intact humerus and the glenoid. The model was developed for the cartilage and the bone of the glenoid and the humerus, using the data from classical research papers. Different sets of simulation were run with both isolated and combined defects to analyze the reaction forces and calculate distance to dislocation. The experiments were analyzed using statistical analysis with displacement control. The results from the study predicted a theoretical model which explains the direct correlation between the anterior stability of glenohumeral joint and the size of the defect. It was found that, with the increase in size of the defect, the distance to dislocation decreased and so does the stability. Presence of both the lesions simultaneously further decreased the glenohumeral stability, for some cases it decreased to zero percent. This data was consistent with our second hypothesis.
