  • Patent number: 10925738
    Abstract: The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally, the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removably locks or helps to removably lock or fix the quasi-spherical member in the bore.

  • Publication number: 20210038233
    Abstract: A patient-specific guide tool for guiding an object toward a glenoid face of a scapula of a patient for implantation of a shoulder prosthetic device is disclosed. The guide tool includes a guide portion that includes a guide surface. The guide surface is configured to guide movement of the object toward the glenoid face. Furthermore, the guide tool includes a patient-specific portion that is operably coupled to the glenoid portion.

  • Patent number: 10588752
    Abstract: A modular bone model can include a bone component and an implant component that can be positioned on the bone component. The implant component can be shaped and sized to correspond to a head component of a medical implant to simulate an articulating surface of the head component.

  • Publication number: 20190175298
    Abstract: Various parallax-free indicator devices, systems, and methods are disclosed. The indicator device may have a housing defining an aperture and a light source assembly at least partially disposed in the housing. The housing may be selectively securable via a fastener to an instrument in a selected orientation relative to the instrument. The light source assembly may have a light source operably coupled to a power source via a power circuit. The light source may be positioned within the housing to emit through the housing aperture. Upon activation, the light source assembly emits a parallax-free alignment indicator along an alignment axis that may have at least one of a selected angle and a selected displacement relative to a selected reference axis. The alignment indicator may guide a surgical procedure.
