Yep,
Sure do.
I have a nice journal article I will email it to you.
The article says most tears happen at the insertion to the humerus and there are a few different described patterns of failure.
But in my clinical practice I see mainly failures occurring at the musculotendinous junction of the sternal head of pec major. I have attached a couple of images.
The clinical presentation sounds suggestive of a pec major tear.
They are often dramatic with obvious clinical deformity and massive bruising. I see them mainly in body builders who are trying to get massive rather than athletes trying to get fit and strong.
I have attached a Pec Major rhabdomyolysis case and a sternal head of pec which has failed at the sternal end.
I have other cases and are hunting them down.
