What is the normal acromiohumeral index?
The AHI is the shortest distance between the inferior cortex of the acromion and the top of the humeral head, the normal AHI is 7–14 mm5,6. Patients with an AHI ≤ 7 mm suggests a large rotator cuff tear4,6 and < 6 mm suggests a longstanding, total infraspinatus tear7.Jun 7, 2022
