Acromial spurs can be quite small and difficult to visualize on MRI. They are enthesophytes that arise from traction at the attachment sites of the Coraco Acromial Ligament and Deltoid. This post looks at the three locations and most common appearances of spurs arising from the lateral aspect of the acromion.
What causes acromion bone spurs?
Weakness in the rotator cuff muscles, which increases the frequency and pressure of contact between the rotator cuff, the bursa and the acromion. Constant rubbing of these structures with increased friction can cause bone spurs to form on the acromion.
Where would you find an anterior Acromial spur?
A subacromial keel is a spur on the anterior under-surface of the acromion, that is formed like the keel of a sailboat. It is highly associated with rotator cuff damage and tear1.
