Study on the Application Value of the Novel Acromial Angle in Diagnosing Rotator Cuff Tears

The NAA in the injury group was generally lower than in the normal group, whereas the CSA and AI were generally higher in the injury group than in the normal group. The measurement value of NAA was better than that of CSA and AI. Therefore, NAA, CSA, and AI are risk factors for rotator cuff tears, and measuring NAA, CSA, and AI helps predict the probability of rotator cuff tears occurrence.
