What is “Supraspinatus Tendinosis”? (Shoulder Pain)

Updated February 14, 2025

If you’ve had an MRI for your shoulder pain, you might be familiar with the term “supraspinatus tendinosis”, which is a very common finding.

The supraspinatus muscle is one of your 4 “rotator cuff” muscles and is a common cause of shoulder pain.

In fact, out of the 4 RC muscles, the supraspinatus is the most likely muscle to show up with tendinosis or to have tears that require surgery.

If you’re curious, here are your other 3 rotator cuff muscles: infraspinatus, teres minor and subscapularis. 

In this video, I explain what “supraspinatus tendinosis” means, and I also explain the anatomical location of this muscle, which will help you understand why it’s so easy to irritate.

If you have any questions, please leave them below the video over in YouTube Land.

Thank you for watching!
