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: A method and device for the percutaneous release of the A1 pulley in the hand, as the triggering of the associated tendon can occur at the A1 pulley in the hand. A blade/hook construct is provided to release the A1 pulley and subsequently confirm the release. The blade and hook are disposed about opposite ends of an elongated shaft, allowing the tool to be used for both cutting and confirming the release of the A1 pulley in the hand. The blade assembly is adapted to avoid damage to adjacent structures, such as nerves and arteries. Advantageously, the A1 pulley may be cut in a distal-to-proximal or proximal-to-distal manner and the percutaneous skin incision may be made centered over the mid-portion of the A1 pulley, or it may be made more proximal or distal.

Abstract: An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of interlocking expansion members or wafers. The like-configured wafers include features on their top and bottom surfaces that interlock the wafers in multiple degrees of freedom so that the wafer stack is not disrupted when the fusion device is fully expanded. One of the interlocking features includes a plurality of prongs projecting from an upper surface of the wafers and into a recess defined in the lower surface of an adjacent previously inserted like-configured wafer. The prongs and recesses are configured to prevent retrograde movement of each new wafer in a direction opposite the direction of insertion. Other interlocking features prevent movement in the direction of insertion, transverse to the insertion direction and vertically within the stack.

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: An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of interlocking expansion members or wafers. The like-configured wafers include features on their top and bottom surfaces that interlock the wafers in multiple degrees of freedom so that the wafer stack is not disrupted when the fusion device is fully expanded. One of the interlocking features includes a plurality of prongs projecting from an upper surface of the wafers and into a recess defined in the lower surface of an adjacent previously inserted like-configured wafer. The prongs and recesses are configured to prevent retrograde movement of each new wafer in a direction opposite the direction of insertion. Other interlocking features prevent movement in the direction of insertion, transverse to the insertion direction and vertically within the stack.

Abstract: Joint fixation systems and methods enabling machining of a plurality of overlapping bores in an articulated skeletal joint with at least one bore on each side of abutting surfaces at the joint. An implant is secured to bones on opposite sides of the joint to immobilize the joint in order to effect fusion of the joint. A jig is used to effect a desired location of the overlapping bores during machining.
