Abstract:
1. A spinal implant system comprising: an intervertebral spacer configured and arranged to be positioned in an intervertebral space between a first vertebra and a second vertebra of a patient; a buttress plate having a plate body configured and arranged to extend across at least a portion of the intervertebral space to at least inhibit the intervertebral spacer from backing out from the intervertebral space when the buttress plate is connected to at least one vertebra, the buttress plate including a top surface and a bottom surface, wherein the bottom surface includes at least one engagement member and a recessed edge and the top surface includes a groove, the buttress plate further comprising a single aperture that extends through the top surface and bottom surface, and the buttress plate comprising generally triangular plate body having three sides meeting at three rounded corners, wherein the recessed edge extends across an apex portion of the plate body; a single screw configured to be inserted through the aperture of the buttress plate and into a single vertebra to connect the buttress plate to the vertebra; and an insertion instrument having a proximal portion, a distal portion, and a sleeve there between comprising a lumen, the insertion instrument further comprising an inner shaft having length defined between a proximal end and a distal end and having a lumen, wherein a majority of the length of the inner shaft is configured to be disposed within the lumen of the sleeve, wherein the proximal portion includes a cap including a delivery hole and a pin actuator for controlling retraction of the inner shaft within the sleeve, and wherein a distal portion of the sleeve includes a receiver portion configured to receive the buttress plate, wherein the receiver portion comprises a recess configured to receive the recessed edge of the bottom surface of the buttress plate, wherein the distal end of the inner shaft is configured to engage the groove of the top surface of the buttress plate, wherein the insertion instrument comprises a spring member configured to force the inner shaft into the groove on the top surface of the buttress plate in an engaged configuration, and wherein the insertion instrument is configured to couple to the buttress plate in the engaged configuration, the insertion instrument is configured to deliver the buttress plate to an implantation site in the engaged configuration such that the at least one engagement member on the bottom surface of the buttress plate engages at least one vertebra, and the insertion instrument is configured to guide the screw through the lumen to the aperture of the buttress plate in the engaged configuration.
