A spinal system comprising: a spacer for inserting into an intervertebral space, the spacer including: an upper surface, a lower surface, and an opening that extends between the upper surface to the lower surface, wherein the spacer further includes a tapered leading end,; a plate for abutting the spacer, the plate including: a plate body, a first opening formed in the plate body for receiving a first bone screw, wherein the first opening is angled in an upward direction; a second opening formed in the plate body for receiving a second bone screw, wherein the second opening is angled in a downward direction; a set screw for preventing back-out of both the first and the second bone screws, wherein the set screw has a first position whereby the first and second bone screws can be inserted past the set screw and into the first and second openings (52, 54) and a second position following rotation of the set screw whereby the first and second bone screws are prevented from backing out by the set screw, and a pair of extensions that extend from the plate body, wherein the extensions are configured to engage the spacer, wherein each extension extends laterally from the plate body and includes a window that extends along a length of the extension and wherein each of the windows receives a hump area of the spacer to provide a locking mechanism between the spacer and the plate; a first bone screw for inserting into the first opening in the plate body, wherein the first bone screw is configured to be inserted into a first vertebral body; and a second bone screw for inserting into the second opening in the plate body, wherein the second bone screw is configured to be inserted into a second vertebral body different from the first vertebral body. a spacer for inserting into an intervertebral space, the spacer including: an upper surface, a lower surface, and an opening that extends between the upper surface to the lower surface, wherein the spacer further includes a tapered leading end,; an upper surface, a lower surface, and an opening that extends between the upper surface to the lower surface, wherein the spacer further includes a tapered leading end,; a plate for abutting the spacer, the plate including: a plate body, a first opening formed in the plate body for receiving a first bone screw, a plate body, a first opening formed in the plate body for receiving a first bone screw, wherein the first opening is angled in an upward direction; a second opening formed in the plate body for receiving a second bone screw, wherein the second opening is angled in a downward direction; a set screw for preventing back-out of both the first and the second bone screws, wherein the set screw has a first position whereby the first and second bone screws can be inserted past the set screw and into the first and second openings (52, 54) and a second position following rotation of the set screw whereby the first and second bone screws are prevented from backing out by the set screw, and a pair of extensions that extend from the plate body, wherein the extensions are configured to engage the spacer, wherein each extension extends laterally from the plate body and includes a window that extends along a length of the extension and wherein each of the windows receives a hump area of the spacer to provide a locking mechanism between the spacer and the plate; a first bone screw for inserting into the first opening in the plate body, wherein the first bone screw is configured to be inserted into a first vertebral body; and a second bone screw for inserting into the second opening in the plate body, a second opening formed in the plate body for receiving a second bone screw, wherein the second opening is angled in a downward direction; a set screw for preventing back-out of both the first and the second bone screws, wherein the set screw has a first position whereby the first and second bone screws can be inserted past the set screw and into the first and second openings (52, 54) and a second position following rotation of the set screw whereby the first and second bone screws are prevented from backing out by the set screw, and a pair of extensions that extend from the plate body, wherein the extensions are configured to engage the spacer, wherein each extension extends laterally from the plate body and includes a window that extends along a length of the extension and wherein each of the windows receives a hump area of the spacer to provide a locking mechanism between the spacer and the plate; a first bone screw for inserting into the first opening in the plate body, wherein the first bone screw is configured to be inserted into a first vertebral body; and a second bone screw for inserting into the second opening in the plate body, wherein the second bone screw is configured to be inserted into a second vertebral body different from the first vertebral body.
