Reverse shoulder cup trial prosthesis

Reverse shoulder cup trial prostheses are copies of final reverse shoulder prosthesis cups designed to be used before primary or revision implant surgery to validate the proper size of the permanent prosthesis required by the patient and to ensure its proper orientation and positioning. These devices connect to a reverse shoulder prosthesis body and articulate with a reverse shoulder prosthesis head, and are used in shoulder joint replacement surgery to confirm implant fit and alignment before permanent prosthesis placement.
