So it's a SLAP Tear.
Had an MRI done today.
Here's the extract from the report:
1. SLAP Tear.
2. Mild articular surface fraying at the insertion of the super status. No full thickness rotator cuff tear.
3. Suspected humeral avulsion of the glenohumeral ligament (HAGL), as evidenced by contrast extravasation through the axillary recess along the medial humeral neck and inferior subscapularis.
I am not a doctor, so I really don't have a deep understanding what the above passage meant.
Basically, something is torn. It needs to be fixed. It doesn't heal by itself and could get progressively worse.
So. I'm an engineer by training. Usually if you have a bearing or a joint fail, you renew or refurbish said bearing or joint.
Since I can't order a new SLAP from the OEM, I will have surgery on 27 OCT 2009 to fix the tear.
