What two ways below does the SMR system help to reduce the risk of scapula notching?
Using a metal back glenoid
Reversing the materials between the glenosphere and the liner
Distal fixation of the stem
Placing a chamfered edge on the liner
Why was there a need to invent the reverse shoulder?
Patients who had avascular neucrosis
Young patients who suffered trauma
Patients with Cuff tear arthropathy
To help prevent overstuffing of the joint

Nothing
What is Scapula Notching?
Metal ions released causing scapula to resorb
Poly debris caused by the poly liner articulating with the scapula and causing bone resorption
A naturally occurring phenomenon
Hyper extension of the shoulder
