I am 76 years 10 months - very healthy and active. However, i threw an object with a backhand flick over my front fence and felt the pain -torn muscles et al.in right shoulder mechanics. My GP says I need a shoulder reconstruction. I said at my age is it worth it. he said its not a matter of age but functionality. I sense discomfort when lying on that side , some arthritis in the joint, but still ahve a fair degree of functionality albeit have reduced capability to lift heavier weights which has curtails my House type repairing function etc. Last night i attached RPA Melbourne when a surgeon did a shoulder reconstruct inserted a prothesis joint et al,. SCARY but all good. Q.1 Will my shoulder muscles atrophy , if so, to what extent and when. should I have the OP ASAP or defer till I have poor functionality.

Hello sir. I would like to know more about your shoulder tear like muscle injured and its grade. If I were your treating doctor then. I would definitely try some strengthening and stability exercises for your shoulder before recommending you for a surgery. If you engage your shoulder in some kind of rehabilitation...this will help you to recover faster post surgery...also help you to improve current functional limitations.so you have very fewer chances of loosing muscle. Following a shoulder surgery again you need to engage yourself in rehabilitation for at least 6 weeks for regaining your strength and stability... I would also suggest you to kindly share with us your MRI or any other investigations taken to help you with some maintenance exercises...as welling my opinion you can defer surgery for a while and try rehabilitation with a physio for six weeks... If rehabilitation fails to improve functionality then we can think of surgical repair. Hope this is helpful for you. Kindly revert in case you need any further help in this regard.
