What is a hooked acromion?
The hooked acromion is a frequent contributor to soft-tissue disorders such as subacromial bursitis, shoulder impingement, and rotator cuff dysfunction. The hook on the end of the acromion takes up crucial subacromial space and causes increased friction on a number of soft-tissues that lie under the acromion.
What is Type 3 acromion morphology?
Abstract. Down-sloped or hooked acromion morphologies may cause bony encroachment on the soft tissues of the subacromial space, predisposing to shoulder impingement syndrome. Of the latter, a hooked or Type III acromion (T3A) has also been linked to rotator cuff (RC) pathology.
What is the most common type of acromion?
type II
This study reveals that type I (flat shape) and type II (curved shape) are the most common types of the acromion in present study accounting for 47.26%, 49.66%. While type III (hooked shape) is a rare form only accounting for 3.08%.

What is a Type 11 acromion?
A type II acromion is considered to be one that in which the acromion has a down-sloping character. • A type III acromion is considered to be present when there is significant downward hooking of the acromion consequently greatly restricting the caliber of the subacromial arch area.
What causes a curved acromion?
Curved or hooked acromion. People who have curved or hooked acromion bones typically have a smaller subacromial space than a person who has a flat acromion.
Can a shoulder impingement be permanent?

Why is there a bone sticking out on top of my shoulder?
Bone spurs (also called osteophytes) consist of excess bone growth around your joints, and are common in older adults. Bone spurs in the shoulders may develop as a result of degenerative joint conditions as well as injuries and general wear and tear.
What muscles attach acromion?
Two major muscles, the deltoid and trapezius, attach to the acromion. The deltoid, which abducts the arm at the shoulder, forms its origin along the acromion, the spine of the scapula, and the clavicle. From these origins, it crosses the shoulder joint and inserts on the deltoid tuberosity of the humerus.
How do you heal acromion?

- Rest. This allows your shoulder to heal.
- Sling. This protects the shoulder and holds the joint in a good position for healing.
- Cold packs. These help reduce swelling and relieve pain.
