Acromiohumeral interval is a useful and reliable measurement on AP shoulder radiographs and when narrowed is indicative of rotator cuff tear or tendinopathy.

Plain radiograph
  • true AP shoulder radiograph
  • measure from the cortical bone at the inferior aspect of the acromion to the humeral head
  • can also be performed on coronal and sagittal oblique T1 MR images
  • inferior aspect of the acromion (marked by black line directly above the humeral head) directly inferiorly to the center of the subchondral cortex of the humeral head


Measurements of the acromiohumeral interval in the following intervals are suggestive of pathology :
