Read the full statement (142 words)

The Catalyst R1 Reverse Shoulder System is a reverse total shoulder replacement for patients with a functional deltoid muscle and a grossly deficient rotator cuff joint suffering from pain and dysfunction due to:

* Severe arthropathy with a grossly deficient rotator cuff:

» Previously failed joint replacement with a grossly deficient rotator cuff;

* Fracture of glenohumeral joint from trauma or pathologic conditions of the shoulder including humeral head fracture, displaced 3- or 4-part fractures of proximal humerus, or reconstruction afier tumor resection;

* Bone defect in proximal humerus;

* Non-inflammatory degenerative disease including osteoarthritis and avascular necrosis of the natural humeral head and/ or glenoid;

* Inflammatory arthritis including rheumatoid arthritis;

* Correction of functional deformity

The humeral stems are intended for cemented or uncemented applications.

The glenoid baseplate is intended for uncemented use with the addition of screws for fixation.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
