Acromial spurs, abnormal bony growths on the acromion (the bony projection at the top of the shoulder blade), can be classified morphologically. Based on the provided reference, the different types include:
- Heel: This type presents as a spur resembling the heel of a foot.
- Lateral/Anterior Traction: This spur is formed due to traction forces at the lateral or anterior aspect of the acromion.
- Lateral/Anterior Bird Beak: This spur type resembles a bird's beak, growing from the lateral or anterior acromion.
- Medial: This type develops on the medial aspect of the acromion.
Acromial spurs are common, with the reference suggesting a 68% incidence in a study group, and their occurrence tends to increase with age. The classification of these spurs aids in diagnosis and potentially influences treatment strategies for shoulder impingement syndrome or other related conditions.
