Type II acromion may occasionally cause impingement of the shoulder joint. The type III acromion is the one which is usually involved with impingement syndrome of the shoulder joint as it is curved like a hook over the rotator cuff and lead to injury and possible tearing of the rotator cuff.

Is type 2 acromion serious?
Type II acromion may occasionally cause impingement of the shoulder joint. The type III acromion is the one which is usually involved with impingement syndrome of the shoulder joint as it is curved like a hook over the rotator cuff and lead to injury and possible tearing of the rotator cuff.
What is acromion type II?
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.
Is type 3 acromion serious?
If you have a Type III or “hooked” acromion, you are more predisposed to shoulder impingement. Secondly, weakness in your posterior cuff (infraspinatus/teres minor) can cause abnormal shoulder mechanics leading to impingement.
What is a Type II distal acromion?
The type II acromion is more curved and downward dipping, and the type III acromion is hooked and downward dipping, obstructing the outlet for the supraspinatus tendon.3 Cadaveric studies have shown an increased incidence of rotator cuff tears in persons with type II and type III acromions.2,3.
How common is Type 2 acromion?
The most commonly encountered type of acromial shapes among both the patients and control groups was type-II (44.6% and 43.3% respectively).
How common is type 3 acromion?
The distribution of acromial types was as follows: type I, flat, 51 (12.1%); type II, curved, 239 (56.5%); type III, hooked, 122 (28.8%); and type IV, convex, 11 (2.6%).
When does shoulder impingement require surgery?
Surgery is only necessary when there is a significantly large rotator cuff tear caused by an acute traumatic event. If impingement results without a tear, surgery may not be needed. A “Scapular Tilt Test,” which I have performed for nearly 15 years, is one way to determine if surgery is needed.
How do you sleep with a shoulder impingement?
Lie flat on your back with your injured arm propped up with a pillow. Using a pillow may help reduce stress and pressure on your injured side. Lie on your uninjured side. If your right shoulder is injured, sleep on your left side.
Does shoulder impingement require surgery?
Severe cases of impingement may require surgery to remove the pressure and create more space for the rotator cuff. The most common procedure for treating impingement is subacromial decompression.
What happens if you don’t treat shoulder impingement?
If left untreated, impingement syndrome can lead to inflammation of tendons (tendinitis) and/or bursa (bursitis). If not treated correctly, the rotator cuff tendons will begin to thin and tear.
