System and method for immobilizing adjacent spinous processes
First Claim
1. A system for immobilizing adjacent spinous processes, comprising:
- a first plate having;
a first adjustable grip adapted for gripping a first spinous process;
a second adjustable grip adapted for gripping a second spinous process;
a first slot at a first position;
a second slot at a second position; and
a third slot at a third position;
a second plate having;
a first adjustable grip adapted for gripping the first spinous process; and
a second adjustable grip adapted for gripping the second spinous process;
a first slot at a first position;
a second slot at a second position; and
a third slot at a third position;
a first pin positioned in the first slot of the first plate and the first slot of the second plate, thereby connecting the first plate with the second plate;
a second pin positioned in the second slot of the first plate and the second slot of the second plate, thereby connecting the first plate with the second plate;
a third pin positioned in the third slot of the first plate and the third slot of the second plate, thereby connecting the first plate with the second plate;
a first spacer moveably connected with the first pin;
a second spacer moveably connected with the second pin; and
a third spacer moveably connected with the third pin.

Abstract
A system and method for immobilizing adjacent spinous processes in accordance with the present invention can supplement primary fusion devices and methods by immobilizing spinous processes while bone from adjacent vertebral bodies grows together. The system requires less extensive surgical procedures than other common supplemental devices, and preferably does not require bone or ligament removal. One such system comprises three spacers positioned between spinous processes and adjustably connected with a plate positioned on either side of the spinous processes. Each plate includes grips, with each grip positioned adjacent to the spinous process, forming a clamp with a grip connected with the opposing plate.
