Doc,
I thought that sounded rather strange. I talked with two of the Ortho guys I work with and they said that since you pull with the muscles of the shoulder you should not have a real problem with the tendon. I was told that it may cause a defect in the forearm but unless this bothers you it should not be a problem. They said depending on if you are a very active sports person they may recomend reatachment. but if not.......... would need to look at things.
The decompression is to give you more room between the rotator cuff and the clavical and the removal of the distal clavical goes along with part of the impengment problem.
bursectomy, Im not sure what he will do, on the nerve damage you may look at some blocks/injections to see if this will help.
Again good luck,
Rick
