Abstract
The present invention provides a sacral-iliac plate having an iliac portion with a first screw hole for receiving a first fastener to secure the iliac portion to the iliac bone. A sacral portion integrated monolithically with the iliac portion is also provided with a second and third screw holes for receiving second and third fasteners to secure the sacral portion to the sacral bone. The sacral portion also includes a tulip for receiving and securing a spinal rod.

A sacral-iliac plate comprising:
- an iliac portion having a first screw hole for receiving a first fastener to secure the iliac portion to the iliac bone;
- a sacral portion integrated monolithically with the iliac portion having a second and third screw holes for receiving a second and third fasteners to secure the sacral portion to the sacral bone, wherein the first screw hole differs from the second and third screw holes, wherein the first screw hole is threaded and the second and third screw holes are non-threaded,
- wherein the sacral portion comprises a tulip for receiving and securing a spinal rod,
- wherein the tulip is integrated with the sacral portion,
- wherein the tulip extends upward from a superior surface of the sacral-iliac plate and forms a channel for receiving the spinal rod in a top-loading manner, the channel configured to extend at least partially along a length of the spinal rod towards the second and third sacral screw holes,
- wherein the first and second screw holes are in line along a first axis,
- wherein the second and third screw holes are in line with the tulip along a second axis,
- wherein the first axis and the second axis are generally perpendicular,
- wherein the tulip is positioned in between the second and third screw holes, and the channel of the tulip is positioned in line with the second and third screw holes, and
- wherein the iliac portion is angled between 35° to 50° with respect to the sacral portion,
- wherein the sacral portion extends from a first end to a second end, wherein the sacral portion includes a first portion extending from the first end to a base of the tulip and a second portion extending from the second end to the base of the tulip, the first portion includes the second screw hole and the second portion includes the third screw hole,
- wherein the first portion has a first thickness that is less than a second thickness of the second portion, wherein the second thickness of the second portion is measured from an inferior surface of the sacral-iliac plate to the superior surface of the sacral-iliac plate adjacent the tulip,
- wherein a prong is disposed directly underneath the tulip and configured to facilitate temporary fixation during installation of the plate.
