Q

What are the indications for hemiarthroplasty vs reverse total shoulder arthroplasty in a pt with rotator cuff arthropathy?

A

Hemi-

1) Young and active
2) Anterior deltoid preserved
3) Coracoacromial arch intact (if no will lead to superior migration of humeral head)

Reverse TSA

1) Older
2) Pseudoparalysis
3) Intact deltoid function (axillary n.)

Hemi can improve pain but does not help function; reverse helps improve pain and function
