I'm confused, is it a partial or a full tear? Also, are you sure that it is muscle belly and not tendon as I am not sure how you would tear a muscle belly in half? Can you possibly post a picture of you flexing it? Not positive it will help but may be able to let me see whether it really is tendon or muscle.
At first it seemed it was the elbow, that's where the pain was at. No external impact but serious bruising. So, doc took MRI of elbow region. There was no sign of tendon tear that needed surgery.
I insisted that it was obvious to me the difference in size or length of the muscle belly. My right tricep (rear long head) seems to only go down half way compared to my left tricep.
They did 2nd MRI of the tricep (above the elbow region) and he confirmed that the tricep was torn. But again it's not the tendon. He said cosmetically it would remain the same without surgery. I am not as concerned cosmetically. I doubt a surgical scar would offset any cosmetic "improvement" with the shape of my muscle.
I am more concerned with strength. The tricep feels so weak when, for example, I am doing flat bench flies with light weight (30 lbs). The closer I get to the right arm being fully extended above the center line of my torso, the more my elbow wants to give out and let the weight come crashing down. I am wondering if that is only due to atrophy. They initially tried to tell me the disparity between left and right tricep could be due to atrophy but my muscles don't atrophy that much that fast after a couple months. I've been training for 21 years. (Man I am getting old.)
As far as partial or full tear, I'm not sure what that means. Doc told me it's only one-third of tricep affected and I asked him "lower or outer" and he said outer. But then he said you have three heads, which I know, but it still confuses me too, because the visible and portion I can feel where my tricep is no longer there (seems to be no longer there) is the lower portion, not outer.
I am at one of the best hospitals for sports medicine in the region but I suspect not one of their top docs. He is younger and was easier to get an appointment with. Now my instincts are telling me to get in to see one of their "jedi masters" because I am not getting the answers I need to make an informed decision.
This medical group of sports physicians care for Chicago White Sox, Chicago Bulls, and one of their surgeons did a phenomenal job replacing my left hip. (I was only 35, 2 years ago). Minimally invasive. You'd never know I had new hip but for a 3 inch incision that has faded and is blending back with surrounding skin (they used glue, not stitches or staples).
The doc I am talking to now has good educational credentials but I suspect I have to go see one of the more experienced surgeons to get a good grasp of what's actually going on under the skin and what I can expect with and without surgery.
The only way for me to take a good picture is with my digital Nikon which is giving me problems. If I tried with camera phone it would be a blur. I wish I could.
