Claim:
1. A humeral trial and implant assembly for total shoulder arthroplasty comprising: a humeral fixation component including a primary bore, wherein said humeral fixation component is configured for fixation to a humerus; an adapter assembly including an adapter, said adapter including an adapter flange and a body portion extending from said adapter flange, wherein said body portion is received in said primary bore of said humeral fixation component; a humeral trial presenting a medial humeral trial face that has a bulbous shape and a lateral humeral trial face that defines a humeral trial cavity, wherein said humeral trial is coupled to said adapter assembly when said humeral trial is in a trialing configuration; a humeral implant presenting a medial humeral implant face that has a bulbous shape and a lateral humeral implant face that defines a humeral implant cavity, wherein said bulbous shape of said medial humeral implant face matches said bulbous shape of said medial humeral trial face, and wherein said humeral implant is coupled to said adapter assembly when said humeral implant is in an installed configuration; said adapter assembly including an adapter plate and an adapter fastener, said adapter plate coupled to said adapter, said adapter plate abutting said adapter flange, wherein said adapter plate and said adapter are discrete components, wherein said adapter plate is received in said humeral trial cavity when said humeral trial is in said trialing configuration, and wherein said adapter plate is received in said humeral implant cavity when said humeral implant is in said installed configuration, said adapter fastener coupling said adapter plate to said adapter, said adapter fastener including an adapter fastener head that tightens against said adapter plate and that is covered by said humeral trial when said humeral trial is in said trialing configuration; a temporary connection releasably coupling said humeral trial to said adapter assembly that provides separation of said humeral trial and said adapter assembly without requiring disassembly of said adapter assembly; and a permanent connection fixedly coupling said humeral implant to said adapter assembly.
