Abstract
An implantable interlaminar-interspinous stabilization system is provided. The system may comprise a U-shaped implantable device having an inferior section, a superior section, a midsection extending therebetween, and pair of lateral walls for engaging a spinous process of a vertebra, each of the lateral walls including an aperture with a countersink for receiving a bone fastener. The system may also include a bone fastener comprising a threaded bolt and a threaded nut for securing the implantable device to the spinous processes. Insertion tools may be provided for aligning the threaded bolt and nut through the apertures of the implantable device.
Claims32
An implantable interlaminar-interspinous stabilization system comprising:
- a U-shaped implantable device comprising an inferior section, a superior section, a midsection extending therebetween, and a pair of lateral walls extending from at least one of the inferior section and superior section for engaging a spinous process of a vertebra, each of the lateral walls including an aperture for receiving a bone fastener;
- a bone fastener for securing the implantable device to the spinous process;
- an insertion tool for inserting the bone fastener through the apertures of the implantable device during implantation of the system;
- and
- a tightening tool configured to cooperate with the insertion tool such that rotation of the tightening tool effects threading of the bolt and nut together.

A method of stabilizing a spine, comprising:
- selecting a vertebral level to be treated;
- positioning a U-shaped implant between two adjacent spinous processes of the selected vertebral level, the implant comprising:
- an inferior section, a superior section, a midsection extending therebetween, and a first pair of lateral walls extending from at least one of the inferior section and superior section, each of the lateral walls including an aperture for receiving a bone fastener, wherein the pair of lateral walls are positioned on opposite sides of a spinous process of the selected vertebral level;
- and
- creating a hole in the spinous process located between the two lateral walls of the implant before passing a bolt through the apertures of the lateral walls;
- and
- securing the implant to at least one of the adjacent spinous processes by passing the bolt through the aperture of one of the lateral walls.

- a U-shaped implantable device comprising an inferior section, a superior section, a midsection extending therebetween, and a pair of lateral walls extending from each of the inferior section and superior section for engaging a spinous process of a vertebra, each of the lateral walls including an aperture for receiving a bone fastener, each of the lateral walls including an aperture for receiving a bone fastener, wherein each aperture of the lateral walls includes a countersink;
- a bone fastener for securing the implantable device to the spinous process;
- an insertion tool for inserting the bone fastener through the apertures of the implantable device during implantation of the system;
- and
- a pair of compression pliers for positioning a spinous process between each pair of lateral walls.

- positioning a U-shaped implant between two adjacent spinous processes of the selected vertebral level, the implant comprising:
- an inferior section, a superior section, a midsection extending therebetween, and a first pair of lateral walls extending from at least one of the inferior section and superior section, each of the lateral walls including an aperture for receiving a bone fastener, wherein the pair of lateral walls are positioned on opposite sides of a spinous process of the selected vertebral level;
- and
- securing the implant to at least one of the adjacent spinous processes by using an alignment tool to pass a nut and bolt through the apertures of the lateral walls, wherein the step of securing includes aligning the nut with the aperture of the lateral wall located on the opposite side of the spinous process as the bolt such that the bolt passes through the spinous process and joins the nut at a threaded connection, and wherein the alignment tool is configured to hold the nut and bolt and align threaded portions of the nut and bolt.

- an inferior section, a superior section, a midsection extending therebetween, and a first pair of lateral walls extending from at least one of the inferior section and superior section, each of the lateral walls including an aperture for receiving a bone fastener, wherein the pair of lateral walls are positioned on opposite sides of a spinous process of the selected vertebral level;
- moving a first spinous process and a second spinous process towards one another before securing the implant to the first spinous process and second spinous process by engaging a top surface of one of the first and second spinous processes with a first portion of a pair of compression pliers, engaging a bottom surface of the other of the first and second spinous processes with a second portion of a compression pliers, and compressing the first and second portions of the compression pliers;
- and
- securing the implant to a first spinous process by passing a first bolt through the aperture of one of the lateral walls of the first pair of lateral walls, securing the implant to a second spinous process by passing a second bolt through the aperture of one of the lateral walls of the second pair of lateral walls, wherein securing the implant includes aligning a nut with the aperture of the lateral wall located on the opposite side of the spinous process as the bolt such that the bolt passes through the spinous process and joins the nut at a threaded connection.
