What is normal acromion?

9-10 mm (range 8-12 mm): normal. 6-7 mm: thinning of supraspinatus tendon. <6 mm: supraspinatus tear.

What does Acromial Downsloping mean?

A downsloping lateral acromion is a variation in acromion shape where the lateral margin of acromion extends to project inferiorly.

How do you treat acromion pain?

If your healthcare provider approves, ibuprofen or naproxen may be taken as-needed to relieve pain. For more severe pain, a stronger prescription strength anti-inflammatory medication may be prescribe or a cortisone injection into the bursa beneath the acromion may be given.

Are subacromial decompression and acromioplasty the same thing?

Acromioplasty is a surgical procedure that involves shaving away part of the shoulder bone called the acromion. Surgeons carry out the procedure to relieve the impingement of the rotator cuff tendon that supports and strengthens the shoulder joint. Acromioplasty is also known as subacromial decompression.

What is an open acromioplasty?

What is Open Acromioplasty? During open acromioplasty, impingement of the acromion of the shoulder is relieved and tears in the rotator cuff are repaired. Also Known As: Shoulder blade surgery.

What is a Type 4 acromion?

In this report, a fourth type of acromion is described in which the undersurface is convex near its distal end. The frequency of a type 4 acromion in the normal population is discussed based on a retrospective review of the MR examinations of 30 patients that originally were read as normal.

What type of acromion is associated with extrinsic impingement?

Impingement and rotator cuff tears attributed to a type III acromion are best appreciated on the coronal and sagittal sequences. 20,35 The slope and angle of the acromion is also associated with extrinsic impingement. Studies have indicated that low lateral acromial angle was seen with a higher incidence of impingement.

What type of acromion is associated with impingement and rotator cuff tears?

Only type III has shown a common association with impingement and rotator cuff tears, by most authors. Impingement and rotator cuff tears attributed to a type III acromion are best appreciated on the coronal and sagittal sequences. 20,35 The slope and angle of the acromion is also associated with extrinsic impingement.

What is the acromion?

The acromion is the top outer edge of your scapula (shoulder blade). It forms the acromioclavicular joint with your clavicle (collarbone) and is located above the glenohumeral joint.
