`ABSTRACT
`Shoulder joint implants are disclosed herein for use in
`shoulder reconstruction that are configured to facilitate the
`inclusion a central bone screw for augmented bone fixation .
`The implant can include a baseplate ( or metaglene ) config
`ured to secure a glenosphere or other prosthetic component
`to the glenoid . To facilitate lateral or proximal insertion of
`a central bone screw through the implant , a throughbore
`defined along the central axis of the metaglene can be
`widened to accommodate the maximum diameter of the
`screw . To enable fixation of the glenosphere to the meta
`glene , a collet can be configured to engage the smaller
`diameter of a glenosphere coupling element and inserted
`into the central throughbore . The collet and the bone screw
`can be separate parts , thereby making insertion of the bone
`screw optional . Alternatively , the collet and bone screw can
`be integrated together to form a unitary construct .
