Have you been told that you have a Massive Rotator Cuff Tear?

[steviewho]

As a 47yr old male with cronic end stage rotator cuff tears along with severe humeral migration rubbing against the acromion,tendon retraction with fatty infiltration. The tears are full thickness,3.5cm left and 4cm right at time of mri Jan,2010. As far as the reverse shoulder which seems to be my only option available, i'm very apprehensive as far as stability and implant failure and if this is even an option for somone under 50yrs.old. I would very much appreciate your opinion. Thank You.
