Claims17
A spinal stabilization system, comprising:
- an implantable device having a main body configured for interlaminar placement between adjacent vertebrae, the main body having a midsection, and an inferior section and superior section extending from the midsection to form a U-shaped body,
- each of the inferior and superior sections having a length and a pair of lateral walls extending therefrom to form a stirrup for receiving a spinous process;
- each of the lateral walls including an aperture for receiving a bone fastener;
- each of the inferior and superior sections further having a U-shaped cutout portion to form a receiving slot, each of the receiving slots having three walls formed around an opening facing the posterior direction, and vertically extending teeth along the length of each wall of a pair of opposed walls to form a gripping surface within the receiving slot to prevent slippage in the posterior direction;
- and
- a bone fastener for securing the implantable device to the spinous process.
