The recent surgery I had in order to reattach my pectoral muscle tendon was a success! After opening me up and seeing the extent of the damage, the surgeon determined it was the best case scenario which meant that the tendon had been detached at the bone, and there was still plenty of good healthy tendon attached to the muscle to work with.
I now have a couple of titanium anchor screws in my humerus bone, to which the tendon is attached with sutures. A good description of the procedure can be found in Scenario #1 of this article that I found on the subject.
I have to keep my arm in a sling for the next 4 - 6 weeks while the tendon grows back into the bone. Until then, any kind of jerky movement in the wrong direction can cause the sutures to tear out. The arm sling has an extra strap on it that wraps around my waist in order to keep the arm closely attached to my body.
After tendon reattaches itself, I’ll still have plenty of physical therapy for a few months but I should be able to start rebuilding the muscle. It can take up to a year to get back to close to 100%. I hope to be there in 6 months :)
The downside of this is that I am going to have to pre-empt my 4 weeks of business travel plans I was supposed to start on today. The surgeon explained that even doing any heavy lifting with my good arm which causes my pectoral muscle to flex, such as lifting luggage, could also send a signal to my damaged pectoral muscle to flex as well, which could tear out the sutures.
