## Indications for use
The Arthrex UNIVERS REVERS COATED BASEPLATE is designed to be used as the glenoid component of the existing Univers Revers Shoulder Prosthesis System. The Arthrex UNIVERS REVERS COATED BASEPLATE is indicated for use in a grossly rotator cuff deficient glenohumeral joint with severe arthropathy or a previously failed joint replacement with a gross rotator cuff deficiency. The patient’s joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. The Arthrex UNIVERS REVERS COATED BASEPLATE is indicated for primary, fracture, or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency. The Arthrex UNIVERS REVERS COATED BASEPLATE is coated and is intended for cementless use with the addition of screws for fixation.
