  • SHOULDER IMPLANT COMPONENTS
    Publication number: 20200129301
    Abstract: A shoulder implant system includes a humeral stem implant, a humeral neck implant component, a humeral head implant component, and a glenoid implant. The humeral stem implant has a fin coupled to an exterior surface thereof that is inwardly tapered at an angle relative to vertical. At least a portion of the fin forms a wedge that directly engages and compacts cancellous bone during installation of the humeral stem implant. The humeral neck implant component is configured to be coupled with the humeral stem implant. The humeral head implant component is configured to be coupled to the humeral stem implant via the humeral neck implant component. The glenoid implant has a plurality of peripheral pegs. Each of the peripheral pegs has a plurality of sets of resilient lobes.
