  • Patent number: 11304815
    Abstract: This set comprises glenoid components that each include a body defining, on two of its opposite faces, respectively, a joint surface, intended to cooperate with a humeral head, and a bearing surface bearing against the socket of a shoulder blade. In this set, the glenoid components are provided in several different sizes, respectively defined by the dimensions of the joint surface of their body. At least two glenoid components of which the bearing surfaces respectively have different dimensional geometries are provided so as to allow the surgeon to improve the durability of the mechanical cooperation between the implanted component and the operated socket.

  • Publication number: 20210228371
    Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

  • Publication number: 20210220151
    Abstract: Various apparatus and methods for implanting glenoid prostheses are disclosed. In various embodiments, a method for performing shoulder surgery can include guiding a guide pin into the glenoid surface along a reaming axis. A partial reaming guide can be placed in contact with the glenoid surface over the guide pin. A reamer can be guided over the guide pin to ream the glenoid surface. The reamer can be further advanced over the guide pin until the reamer contacts the partial reaming guide, whereby such contact limits reaming to only a portion of the glenoid surface.
