A guide is disclosed for use in performing spinal surgery to prepare across a spinal disc and adjacent vertebrae an implantation space. The guide is associated with a computer controlled surgical navigation system employing an energy-detecting array to track positions of the guide in three dimensional space relative to a known reference point. The guide comprises a body for providing protected access to prepare across the spinal disc and into the adjacent vertebrae the implantation space. The body has a passage adapted to receive a bone removal device for forming the implantation space through the body. At least one electrically energizable energy emitter array is attached to the body for use in identifying the location of the guide relative to the adjacent vertebrae. A system and method for using the guide in spinal surgery are also disclosed.

606 87, 606 90

A guide and method of using the guide for positioning within a patient between vertebral members for contouring each of the members. The guide comprises a first section and a second section. A first edge is positioned along an edge of the first section, and a second edge is positioned along an edge of the second section. One or more elongated rods extend through the sections. One or both of the sections are movable along the rods to adjust a spacing between the first edge and the second edge. When positioned within the patient, the first edge is aligned along a first vertebral member and the second edge is aligned along a second vertebral manner. A manner of locking the sections is included for preventing the sections from moving relative to each other once the first and second edges are aligned within the patient.

Methods and devices for performing percutaneous surgery in a patient are provided. A retractor includes a working channel formed by a first portion coupled to a second portion. The first and second portions are movable relative to one another from an unexpanded configuration to an expanded configuration to increase the size of the working channel along the length of the working channel while minimizing trauma to skin and tissue.

A method for accessing the spine includes making an incision in the skin of a patient. The skin and tissue can be dilated, and a cannula inserted through the dilated skin and tissue. The cannula includes a distal end positioned adjacent a first working space that includes paraspinous tissue. The cannula can be repositioned through the incision to a second working space adjacent the distal end of the cannula.

Devices and methods to restore the disc height between adjacent vertebral members. The methods use a variety of different spacers that are each positionable between a first orientation having a reduced height and a second orientation having an enlarged height. The spacer is initially placed within the disc space in the first orientation. The spacer is then expanded to the second enlarged orientation to restore the disc height. While the spacer is expanded or while it is expanding, the material is inserted into the disc space. In one embodiment, the material is initially in a first flowable form that fills the disc space. After the material is inserted, it becomes more viscous to support the vertebral members. At this time, the spacer is returned to the first orientation and removed from the disc space. The material remains within the disc space to permanently maintain the disc height.

An apparatus and procedures for percutaneous placement of surgical implants and instruments such as, for example, screws, rods, wires and plates into various body parts using image guided surgery. The invention includes an apparatus for use with a surgical navigation system, an attaching device rigidly connected to a body part, such as the spinous process of a vertebrae, with an identification superstructure rigidly but removably connected to the attaching device. This identification superstructure, for example, is a reference arc and fiducial array which accomplishes the function of identifying the location of the superstructure, and, therefore, the body part to which it is fixed, during imaging by CAT scan or MRI, and later during medical procedures.

A method and apparatus for determining, calculating, and/or viewing a trajectory. The trajectory can be displayed on a display relative to image data of a patient. A user can use the system to determine relationships between two or more trajectories that have been determined. The relationships can be within two dimensional, three-dimensional, or four dimensional space. The relationships can include distance, angle, etc. The relationships can also be determined between real time trajectories and stored trajectories, or combinations thereof.

A system and method for discriminating tissue types, controlling the level of therapy to tissue, and determining the health of a known tissue by measuring the characteristics of an electrical signal applied to a conductive element located within or by the tissue. Additionally, the system and method may be used for determining whether the conductive tip of a pedicle probe or pedicle screw is located in one of cortical bone, cancellous bone, and cortical bone near a boundary with soft tissue, whether the conductive tip of a cannula is located adjacent to one of nerve tissue and annulus tissue, and whether the conductive tip of a cathode is located adjacent to one of nerve tissue and prostate gland tissue.

Methods and instrumentation for surgical procedures relating to preparation of vertebral bodies and a disc space for insertion of spinal implants is disclosed. One instrument is a shim having a blade and a shaft having a first end connected with the blade. The blade is inserted into a distracted disc space to maintain distraction during subsequent procedures. Another instrument is a driver for driving the blade of the shim into the distracted disc space. Various methods contemplate the use of these instruments to maintain disc space distraction during disc space preparation for receiving an implant.

A modular intervertebral prosthesis system includes first and second baseplates and an insert designed to mate to the baseplates. The baseplates include a mounting section and a intervertebral section extending away from the mounting section generally perpendicular thereto. The intervertebral section has at least one aperture passing therethrough. When installed, the insert is disposed between the intervertebral sections of the baseplates and faces the apertures. In this way, the insert is not insulated from the vertebral members, thereby allowing for osteoinduction, osteoconduction, and/or osteointegration, if desired. The insert may take the form of an articulating-type insert or a fusion-type insert, with the baseplates being operative with both types of inserts. After installation of the insert between the baseplates, the insert may be readily removed, at least initially.
