In various embodiments, a kit for shoulder surgery can include a partial reaming guide having a patient-matched surface shaped to conform to a scapula of a patient, the partial reaming guide configured to limit glenoid reaming about a reaming axis to only a portion of a glenoid; and an anchor peg channel guide having a patient-matched surface shaped to conform to a portion of the glenoid, the anchor peg channel guide having a channel offset from the reaming axis.

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.

Abstract: An implant is disclosed that a base member configured to be secured in bone, the base member includes a plate portion, an articulating member, and a coupling portion for securing the base member to the articulating member. A stem extends from the plate portion, where the stem is positioned offset from a center of the plate portion. The coupling portion includes a first fixation component, and a second fixation component including an opening for receiving the first fixation component, where the first fixation component is coupled to the articulating member and the second fixation component is coupled to the base member.

Abstract: An implant is disclosed that has a base member, an articulating member, and a coupling portion that secures the base member to the articulating member. The implant can be a shoulder implant (100, 200, 300) that has a baseplate (102, 230, 310), an articulating component (104, 210), and a fixation component (106, 270, 342). The baseplate includes a first side (110, 234, 314) with a projection (108, 240, 320) that has a first Morse taper and may be offset from a center line of the baseplate and a second side (116, 236, 316) that has a post or stem (114, 250, 330) that is offset from the center line of the baseplate. The articulating component includes a cavity (122, 220) with a second Morse taper that is offset from a center line of the articulating component. The articulating component is attachable to the baseplate when the projection is received in the cavity of the articulation component.

Abstract: A surgical anchoring device may include a first beam and a second beam each extending along a longitudinal direction; and a connecting member bridging a first proximal portion of the first beam to a second proximal portion of the second beam such that the first beam is substantially aligned with the second beam.
