I've been diagnosed with a supraspinatus tendon rupture of about 1.1 x 1.2 mm on the supraspinatus tendon (posterior fibers). Roughly, how big is it in relationship with its global size? Half? 2 thirds? I'm a small guy - 1.6m tall.
Also, does the tendon recover?
I notice my arm is still a little bit anterior rotated and down a bit as well. About a year has passed.
Should I be worried with some kind of arthrosis down the line, because of the position of the humerus on the glenoid cavity?
Since tendons connect bone to muscle, they have some blood flow and can possibly heal. But ligaments connect bone to bone, so there is no blood flow and they cannot heal themselves. Thus tendon tears have a greater likelihood of healing without intervention. But the shoulder is a daily driver, and repairs can make life way easier, especially with a shoulder to chest tendon like the supraspinatus!
