Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described. |

1. A reverse shoulder prosthesis system, comprising:
a baseplate comprising:
a body having an oblong configuration and including:
a lateral side,a medial side,a first end comprising a first bore extending through the body from the lateral side to the medial side; anda second end positioned opposite the first end and comprising a second bore extending through the body from the lateral side to the medial side, the first end and the second end defining the oblong configuration;a threaded component; anda shaft having a hydroxyapatite coating positioned between the body and the threaded component; a glenosphere component comprising:
a medial side including a recess configured to receive at least the lateral side of the baseplate body such that the first end and the second end of the baseplate body is positioned in the recess;a lateral side; anda tapered trunnion; a humerosocket component comprising:
a medial side;a lateral side;a projection positioned on the lateral side of the humerosocket component; andan articulating face defined in the medial side of the humerosocket component and configured to receive the lateral side of the glenosphere component; and a humeral component comprising:
a distal stem configured to be fitted within a prepared proximal end of a humerus of a patient;a transition region including an aperture extending through a portion of the transition region; anda proximal head defining a cavity extending distally into the proximal head, the cavity configured to receive the projection of the humerosocket component. |
