Critical Shoulder Angle in Patients With Cuff Tears

Background: The Critical Shoulder Angle (CSA) is an important anatomical measurement associated with rotator cuff tears and shoulder dysfunction. It is defined as the angle between the glenoid plane and the acromion, and its value may influence the risk of rotator cuff tears. Understanding the relationship between CSA and cuff tears can help physicians identify patients at higher risk and guide treatment decisions. This study explores the significance of CSA in patients with rotator cuff tears and its potential implications for surgical outcomes. Methods: This research utilized a retrospective analysis of patients diagnosed with rotator cuff tears between ۲۰۱۰ and ۲۰۲۴, who underwent imaging studies, such as X-rays or MRIs, to measure the Critical Shoulder Angle. The authors reviewed clinical records to gather data on demographic profiles, tear characteristics, surgical interventions, and postoperative outcomes. Statistical analyses were conducted to assess the correlation between CSA measurements and various factors, including tear size, patient age, and postoperative functional outcomes. Results: The analysis revealed that a larger Critical Shoulder Angle is significantly associated with an increased incidence of rotator cuff tears. Specifically, patients with a CSA greater than ۳۵ degrees were more likely to present postoperatively with larger tears and poorer functional outcomes. Additionally, these patients experienced higher rates of postoperative complications and longer recovery times compared to those with normal CSA. Furthermore, the data suggests that measuring CSA can serve as a useful predictive tool for assessing surgical risk in patients undergoing rotator cuff repair. Overall, the findings indicate that CSA should be considered in preoperative assessments to better inform surgical planning and patient counseling. Conclusion: The Critical Shoulder Angle is a significant anatomical factor in patients with rotator cuff tears, influencing both the likelihood of tears occurring and postoperative outcomes. By incorporating CSA measurements into clinical practice, orthopedic surgeons can enhance their ability to predict surgical risks and effectively implement treatment strategies. Future research should focus on prospective studies to further validate these findings and explore potential interventions that could mitigate the risks associated with elevated CSA values.
