COMPREHENSIVE® REVERSE SHOULDER Mini BasePlate

Evaluate Survivorship for the Biomet® Comprehensive® Reverse Shoulder Mini Baseplate.

Evaluate Survivorship for the Biomet® Comprehensive® Reverse Shoulder Mini Baseplate.

The primary objective of this prospective clinical data collection is to evaluate survivorship for the Biomet® Comprehensive® Reverse Shoulder Mini Baseplate. Secondary objectives include validation of implant sizing and hardware options as well as collection of mid-term clinical outcomes including adverse events, scapular notching, and Constant Score.

All shoulders on which data will be collected are legally marketed and none of the devices are investigational or experimental. FDA has cleared this device via Premarket Notification 510(k) K080642. This data collection effort will document the clinical outcomes of the Comprehensive® Reverse shoulders. The data gathered will be collated and used to provide feedback to designing engineers, support marketing efforts, and answer potential questions from reimbursement agencies.

   2. Primary total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency, or
   3. Fracture total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency, or
   4. Revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency.
