Glenoid Bone Quality: Predicting Cement Stress in Total Shoulder Arthroplasty

This lecture discusses the importance of glenoid bone quality in total shoulder arthroplasty, focusing on predicting cement stress through finite element models. The study includes methods for assessing bone quality, patient-specific parameters, and correlations between bone quality and cement stress. Results show a strong correlation between reamed subchondral bone quality and cement stress. The discussion covers the clinical relevance of the findings, including factors affecting bone quality and the impact on aseptic loosening rates. In conclusion, preserving glenoid bone quality is crucial for successful total shoulder arthroplasty, emphasizing the significance of preoperative planning and potential use of augmented glenoid implants.
