Abstract: The pedicle screw extension system may include a removable cannulated extension provided to a pedicle screw tulip head. The cannulated extension may permit percutaneous implantation of pedicle screws followed by rod placement that may be guided by slots running along the length of the extension. The cannulation may allow for passage and attachment of secondary instruments, such as for example: a screw driving device, a rod measuring device, and a set screw driving device. The screw extension may also include secondary device attachment features allowing the rod to be pushed down in a screw tulip head and for extension removal as needed.

Abstract: A method of performing percutaneous interbody spinal fusion on adjacent vertebrae in a patient including the steps of: creating a percutaneous access opening on the patient, using indirect visualization to establish a surgical path through the access opening via neural monitoring, creating a cavity in a disc space between the adjacent vertebra, without retraction, evaluating the created cavity, inserting a container sized and configured to fit through the access opening into the cavity and filling the container with fill material.

Abstract: A method of performing percutaneous interbody spinal fusion on adjacent vertebrae in a patient including the steps of: creating an access opening on the patient, the access opening being less than 10 mm wide, using indirect visualization: establishing a surgical path through the access opening via neural monitoring, creating a cavity in a disc space between the adjacent vertebra, evaluating the created cavity, inserting a container sized and configured to fit through the less than 10 mm access opening into the cavity and filling the container with fill material.

Abstract: A pliable band or hoop that is flexible to normal handling, but cannot stretch circumferentially once it has reached the limits of its circumferential length. The band may have a structural portal to be used for filling, or it may simply be constructed of a fabric-like material that allows a fill tube to perforate its walls to allow for filling. In the latter case, the perforated wall tends to self-seal once the fill tube is withdrawn. The band may be flat or tubular in cross-section. However, unlike a balloon, the band does not require either a bottom or a top, as we found that a top and bottom are unnecessary when using a band or hoop to enclose material injected into a reamed out intervertebral space.

Abstract: A system, device and method for performing a transiliac approach for L5-S1 interbody fusion is disclosed. The surgeon may determine the access location using a neuromonitoring probe and fluoroscopy. Once the location is determined, the surgeon may use a cannulated needle or Jamshidi to create an initial pathway through the ilium. In an embodiment of the present invention, the surgeon may then advance a needle or Jamshidi through the ilium, just medial to the ilium wall. A guide pin may then be advanced through the cannulated needle or Jamshidi until the distal tip of the Jamshidi is reached. The Jamshidi may then be removed.

Abstract: The invention provides a method of correcting numerous bone abnormalities including bone tumors and cysts, avascular necrosis of the femoral head, tibial plateau fractures and compression fractures of the spine. The abnormality may be corrected by first accessing and boring into the damaged tissue or bone and reaming out the damaged and/or diseased area using any of the presently accepted procedures or the damaged area may be prepared by expanding a bag within the damaged bone to compact cancellous bone. After removal and/or compaction of the damaged tissue the bone is stabilized.

Abstract: The present invention is a kit and a method of using a kit for treating bone including a fill material mixture made of osteoconductive material, osteoinductive material and a lubricating carrier, a porous container to receive the fill material mixture and a tool that flowably introduces the fill material mixture into the porous container.

Abstract: A cannulated bone screw having a cannula or lumen defined herein is disclosed. The screw may be fully or partially threaded and may have a cancellous thread form. Alternatively, the head of the screw may be generally flat on its undersurface. The screw head may further include an anti-backout feature to ensure good contact with the mating bone surface. The screw may further include an anti-rotation feature on the underside of the screw head. It is further disclosed that insertion and seating of the screw may be accomplished via locking engagement between jaws on the screw driver and a short raised feature on the head of the screw. The screws may be fully or partially threaded. A rescue screw is additionally disclosed.

Abstract: The present invention is a system for a partially biological disc replacement that stimulates natural fibrous, cartilaginous or other tissue growth in the DDD cavity, resulting in a partial biological disc replacement. Multiplicities of fibronous pieces of fibro-cartilaginous tissue promoting material are inserted into the DDD cavity inducing tissue growth.

Abstract: A composition for spinal disc repair comprising a plurality of uniformly shaped demineralized cancellous bone pieces ranging in size from about 2.0 mm to about 4.0 mm loaded into a porous mesh container with the cancellous bone pieces being treated so that they are not osteoinductive and are packed in the porous mesh container under compression forces.

Abstract: An implantable container is used to stabilize or restore height in a vertebral body. After insertion the container is filled with a bone filler material such as bone cement.

Abstract: An anchorless non-invasive force dissipation device for orthopedic instrumentation including a base having a patient contacting surface, the patient contacting surface including a surface area adapted for external placement on a patient's body, and an instrument alignment mechanism operably connected to and selectively positionable relative to the base, the instrument alignment mechanism adapted to interface with at least one orthopedic instrument, such that forces applied by the orthopedic instrument are dissipated across the surface area of the base with the device being unanchored externally of the patient.

Abstract: A method of treating a compression fracture in a bone comprising the steps of forming a transverse cavity within said bone defined by at least one substantially flat surface lying substantially in a transverse plane formed by and communicating with said transverse cavity, the transverse cavity having a substantially uniform transverse extent and a maximum height, the maximum height being less than said transverse extent and applying a force within said transverse cavity generally normal to said surface to displace said surface and restore said bone to its substantially normal anatomic position.

Abstract: A pliable band or hoop that is flexible to normal handling, but cannot stretch circumferentially once it has reached the limits of its circumferential length. The band may have a structural portal to be used for filling, or it may simply be constructed of a fabric-like material that allows a fill tube to perforate its walls to allow for filling. In the latter case, the perforated wall tends to self-seal once the fill tube is withdrawn. The band may be flat or tubular in cross-section. However, unlike a balloon, the band does not require either a bottom or a top, as we found that a top and bottom are unnecessary when using a band or hoop to enclose material injected into a reamed out intervertebral space.
