We investigated the relationship between four acromial shapes by magnetic resonance imaging (MRI), and the characteristics and occurrence of rotator cuff tears (RCTs). This retrospective study included 621 patients aged 18-90 years who underwent shoulder imaging in the Turgut Ozal University, Training and Research Hospital, Department of Radiology from April 2022 to May 2022. The study reviewed a total of 621 patients, including 377 (60.7%) female, and 244 (39.3%) male patients. Of the total 621 MRI imagines of the patients, 344 (55.4%) were MRIs of the right shoulder, and 277 (44.6%) were MRIs of the left shoulder. No tears were detected in 20.7% of them, and various grades of tears were detected in 79.3% of them. Of the total, 43% had the full thickness and complete tears, and 36.3% had partial tears. A correlation was found between the RCTs and females (p<0.001). No statistically significant relationship was found for left or right shoulder (p<0.065) and acromion type and tear (p=0.465). A correlation was found between the mean acromio-humeral distance of acromion type I, II, and III (mean of three acromion types) and type IV (p<0.001). There were statistical differences between impingement and acromion hypertrophy (ACH) (p<0.001), between tear and impingement (p<0.001), and between tear and ACH (p<0.001). There was no relationship between acromial shape and gender. However, from the point of view of acromial shape, supraspinatus injury and gender were significantly related, namely; right-sided partial tear injuries are more common in females ≥50 years of age with type II acromion shape than with other RCTs.
