Patent ID: 8545511

Claim:
A reverse shoulder system comprising: at least one stem member having a shaft portion adapted to be received in a canal of a humeral bone of a patient; a trial cup and a prosthesis cup each adapted to be coupled at a distal end thereof to the at least one stem member, the trial cup and prosthesis cup each having a proximal end surface including a recess therein; a trial insert and a prosthesis insert each including a proximal end surface and a shaft portion having a distal end, the shaft portion of the trial insert and prosthesis insert each adapted to be received in the recess of the trial cup and prosthesis cup, respectively, wherein a linear trial distance is measured between the proximal end surface of the trial cup and the proximal end surface of the trial insert when at least a portion of the trial insert is coupled to the trial cup and is linearly adjusted into a desired position during trialing, and wherein a linear prosthesis distance is measured between the proximal end surface of the prosthesis cup and the proximal end surface of the prosthesis insert when the prosthesis insert is coupled to the prosthesis cup, and wherein the linear trial distance is substantially the same as the linear prosthesis distance.
