ugh, I saw Ca2+ and stopped thinking.

I was thinking along the lines of overhead motion - damage to the subacromial bursa which is between the acromion and the supraspinatus ... also its the most commonly injured rotator cuff m. so could have guessed this one right
Thanks for the explanation. I was scratching my head as to why this is correct, since supraspinatus only does 15 degrees of abduction, but you make a lot of sense.
why would injury to supraspinatus cause weakness with internal rotation though?
yeah coz of that i picked subscapularis
ya the whole question pointed to supraspinatus ...but last line internal rotation made me pick subscapularis
I went for Trapezius. That shoulder flexion thing was a big distraction. Silly me.
