Abstract: An interbody spacer for use in spinal procedures. The interbody spacer has one or more surfaces with a unique surface pattern. The interbody spacer is preferably designed for use as an intervertebral spacer in spinal fusion surgery, where portions of an affected disc are removed from between two adjacent vertebrae and replaced with an interbody spacer that provides segmental stability, may correct a deformity, and allows for bone to grow between the two vertebrae to bridge the gap created by disk removal. The interbody spacer has one or more unique surfaces designed to aid in bone growth and attachment. The unique surface comprises one or more surface projections, referred to generally as surface projection pattern or matrix, which can be arranged to form unique patterns and structures.

Abstract: The invention involves a device and method for acquiring bone marrow aspirate. The system includes an elongated cannulated fastener having a threaded end for attachment to a bone. The threaded portion includes a directional aperture sized to allow marrow to be drawn into the cannula. The directional aperture also allows the user to direct the aperture in a desired direction within the bone for acquisition of the marrow. The distal end of the cannulated fastener includes a connector which may be in the form of a Luer lock to allow vacuum to be applied to the cannula for drawing the marrow into a syringe or the like.

Abstract: The present invention provides for a bone fixation device, an implantation instrument, and system which are useful in bone fixation surgeries. The bone fixation device of the instant invention allows the surgeon the ability to navigate the rod while being inserted into a pedicle screw assembly through a non-linear pathway by incrementally changing the direction of travel as desired.

Abstract: The present invention provides an orthopedic surgical tool for moving an implant to a surgical sight and installing the implant. The tool allows the surgeon the ability to navigate the implant through a surgical tube, then rotate the implant after reaching the sight and effect installation of the implant, and then effect its release from the tool. The implant can be rotated at any time during its installation within the constraints of other surgical devices.

Abstract: Joint fixation systems and methods, enabling: drilling one or more major bores in a joint; drilling one or more minor bores in the joint, wherein the one or more minor bores are disposed about a periphery of and partially overlap the major bore(s); and disposing an implant in the major bore(s) and the one or more minor bores, wherein a cross-sectional shape of the implant substantially conforms to a collective cross-sectional shape of the major bore(s) and the one or more minor bores. Prior to drilling the major bore(s) or the one or more minor bores, a portal tube is disposed adjacent to the joint, thereby providing access to and stabilizing the joint. A drill guide tube is disposed concentrically within the portal tube, and a drill guide is disposed concentrically within the drill guide tube. Subsequent to drilling the major bore(s) and the one or more minor bores, an implant guide tube is disposed concentrically within the portal tube.

Abstract: A process for inserting a pivotable interbody spacer including an insertion instrument configured to manipulate a pivotable interbody spacer during insertion, wherein the insertion instrument includes means for coupling the interbody spacer and a means for fixing the angular position of the interbody spacer. According to one method for inserting an interbody spacer in a spinal disk space, the interbody spacer is grasped by the insertion instrument and fixed at a first angular position. The interbody spacer is next inserted into a surgical site. Next, the interbody spacer is released from a first angular position. Then, the insertion instrument is pivoted about a coupling of the interbody spacer such that the interbody spacer is in a second angular position. The angular position of the interbody spacer is then fixed in the second angular position. This insertion process continues until the interbody spacer is positioned in the desired location.

Abstract: The present invention is directed to implantable devices for stabilizing or fusing bone structures within the spine. More specifically, the present invention is a spinal plate assembly that includes an automatic mechanism for blocking the pathway of a bone fastener once inserted to prevent unwanted backwards migration of the bone screw.
