The Bridging Sign In Rotator Cuff Tears on Shoulder MRI

-------------

In this video, I show you the bridging sign in extensive rotator cuff tears and what it looks like on a shoulder MRI.

I’m PD Dr. med. Christoph Agten, an MSK radiologist and mentor. I founded the Virtual MSK Fellowship, where 200+ radiologists have mastered MSK faster than they thought possible. I’m a teleradiologist who's completed MSK fellowships in Zurich and NYU, written 40+ research papers, and published the bestselling book SPEED MSK.

VERY GOOD VIDEO !! THIS HAS ALWAYS BEEN KNOWN AS THE COMMA SIGN, WHICH IS AN ARTHROSCOPIC SIGN FOR EXACTLY THE SAME FINDINGS. IT SERVES THEM TO BE ABLE TO FIND THE SUPERIOR ANTERO MARGIN OF THE SUBSCAPULARIS FOR REINSERTION.

Excellent concept, Christ! Thank you for bringing modeling clay into the game!

Very helpful for orthopedic surgeons. Thank you

Love your channel, even though I mostly just do general radiology.

Thanks. Is the bridging sign related to the fact that the rotator cuff tendons are connected via the supporting ligaments (coracohumeral ligament, SGHL, rotator cable). Thus when you have contiguous RC tears, the supporting ligaments remain intact and are responsible for the bridge formation?

I have lateral down slopping of the acromium, is there any exercises that could help me?

[AhmedMahmoud-pqhn]

thanks a lot. actually I've seen so many cases like this and was describing retracted adherent edges so the this description is so valuable scientific and brief expression. but could bridging be described also between chronic ACL and PCL tears at knee joint?

What is the difference between "bridging sign" and "comma sign"? Thanks in advance.

What are your sequences of choice for evaluating rotator cuff tear?
