  • Publication number: 20240065682
    Abstract: A retractor assembly that includes a base portion in slidable engagement with two or more retractor arms with at least one of the retractor arms releasably securing a retractor blade configured to be anchored to a bone anchor. The retractor blade includes an elongate blade portion with a retractor engagement portion positioned at the proximal end of the elongate blade portion and an anchor mechanism positioned at the distal end of the elongate blade portion. The anchor mechanism includes a first jaw and second jaw configured to engage the bone implant. When closed around or anchored to the bone implant—which may be a shank of a modular screw system—the components of the modular screw are able to be assembled to the shank without adjusting, loosening, or opening the anchor mechanism.

  • Publication number: 20230285163
    Abstract: The present disclosure relates to an expandable interbody that includes superior and inferior shells enclosing a control mechanism that includes interlocking proximal and distal cages as well as an adjustment screw that longitudinally translates the distal cage relative to the proximal cage and thereby expands interbody by pushing apart the distal ends of the superior and inferior shells.

  • Publication number: 20230102897
    Abstract: The present disclosure relates to expandable interbodies that include superior and inferior shells and a control assembly positioned between and inside of the shells, the control assembly including nested cages operably connected to each other with an adjustment screw. Rotation of the adjustment screw translates the cages relative to each other, which in turn causes the shells to open or expand.
