Acromial spurs can be quite small and difficult to visualise 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.
1. LATERAL BEAK LIKE SPURS
Beak like spurs form on the lateral tip of the acromion. They can project either

1. The rounded appearance of the lateral margin of the acromion is lost.
2. The cortex and marrow of the acromion are continuous around and into the spur.
|2. ANTERIOR BEAK LIKE SPURS|
|These are seen on sagittal scans as they project anteriorly from the acromion and occur at the attachment site of the coraco acromial ligament.
|3. BROADBASED UNDERSURFACE SPURS:|
