Re: Shoulder Replacement?
Definitely see a shoulder specialist, no one else! You didn't mention your age. People do have them at any age, but since replacements are not guaranteed to last forever, the older you are before having it done, the better.
I had one done 2 months ago. I also had 4 previous surgeries but my problem was caused by trauma. The injury caused complete tears of the supraspinatus and infraspinatus, and there was a compression fracture of the humeral head. The 4th surgery was a humeral head resurfacing - a hemiarthroplasty without a stem, just a "cap" over the humeral head where the defect was located. This was malpositioned, so it caused arthritis of the glenoid and displacement of the joint.
Anyway, a replacement is usually only done for arthritis (lack of cartilage). You need an intact rotator cuff for a conventional replacement.
Most people do very well with the replacement. I am still struggling quite a bit since it was a revision surgery and the shoulder was a major mess overall. Your life style may have to change, depending on what you do for work and recreation. In general, the pain is not much worse than a rotator cuff repair and the recovery can be quicker.
In sum - go to the best shoulder surgeon you can.
