Abstract: An apparatus is provided for supporting a surgical component adjacent to a bone during a surgical procedure. The apparatus includes an integral body having a hinge platform, a hinge integral with the hinge platform; and a surgical component mounting portion integral with the hinge for rotation generally about a hinge axis relative to the hinge platform. An adjustment mechanism is operably connected between the hinge platform and the surgical component mounting portion to allow selective incremental rotation of the surgical component mounting portion relative to the hinge platform.

Abstract: A method is provided for treating a spinal condition. The method includes introducing a biological treatment into an area of a vertebral column, and mechanically unloading the treated area by applying a load-bearing device to the anterior region, the anterior column region, the posterior region, or the spinous process region of the vertebral column.

Abstract: Systems and methods for positioning a connecting element adjacent the spinal column in minimally invasive procedures include instruments that guide the connecting element from a location remote from one or more anchors to a location proximate to the one or more anchors. The instruments include extensions mountable to anchors, and inserter instruments mountable to the connecting element for positioning the connecting element adjacent the anchors in a minimally invasive procedure. The inserter instruments need not be mounted to the anchors or to the anchor extensions, and are operable independently thereof to position the connecting element into the patient along a minimally invasive insertion path from a location remote from the anchor extensions.

Abstract: A chisel system for harvesting an implantable graft from an area of a human having a cartilage overlying a condyle, according to which a module is provided that has one end connected to a handle. A cutting surface is formed at the other end of the module that cuts through the cartilage and condyle.

Abstract: The present application is directed to devices and methods for positioning a rod within a patient. One embodiment of the device may include an elongated inserter having a first end and a second end. A connector may be attached to the second end of the inserter for releasably connecting to the rod. The connector may be adjustable between a first position with the rod substantially coaxially aligned with the inserter, and a second position with the rod substantially perpendicular to the inserter.

Abstract: An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing signal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting assembly.

Abstract: The present invention relates to a transbuccal plate holding cannula used in osteofixation procedures. The transbuccal plate holding cannula of the present invention can be releasibly secured to a bone plate such that tools and fasteners may be passed through the plate holding cannula in order to secure the bone plate to a bone.

Abstract: A tool for inserting or removing an intervertebral implant. The tool includes a first arm having a curved tip adapted for engaging a side wall groove of the intervertebral implant and a second arm pivotably coupled to the first arm. The first arm defines a first concave distal surface extending continuously from the curved tip and the second arm defines a second concave distal surface. The first and second concave distal surfaces define an engagement surface engageable to a substantially complementary convex end wall of the intervertebral implant.

Abstract: A minimally invasive, fluoroscopically guided system is disclosed for stabilizing the articular facet joints of adjacent vertebrae. Ring and dowel implants are disclosed for installation into the facet joint. The invention includes a novel spine surgical training aid used in the initial surgeon training process for refreshing the surgeon's perspective of the critical three dimensional anatomy of the vertebrae. The invention also includes a surgical kit having a range of size-specific drills, inserters, impactors and custom-length long k-wires matched to the internal diameter of the instrumentation system.

Abstract: A fastener and a bone fixation assembly for the internal fixation of vertebral bodies such as a pedicle screw is provided which allows a detachable tulip to be provisionally locked to a pedicle screw, while separately, the rod securely locks to the tulip. According to one exemplary embodiment, the tulip assembly includes a tulip body and an inner tulip member, the tulip body having a non-circular surface disposed on an outer surface. Additionally, a fastener is coupled to the tulip assembly and positionable to retain the tulip assembly on the head of a screw. Further, a cap having an outer surface and a plurality of inner protrusions is provided, wherein the plurality of inner protrusions are configured to mateably connect to the non-circular surface on the tulip body to compress the tulip assembly and secure a rod.

Abstract: A method of percutaneously implanting a first component and a second component of an orthopaedic assembly into a body of a patient includes the steps of securing a first instrument to the first component, and advancing the first component into the body of the patient. The first instrument is advanced into the body of the patient such that a portion of the first instrument extends out of the body. A second instrument is secured to the second component, and the second component is advanced into the body of the patient. The second instrument is advanced into the body of the patient such that a portion of the second instrument extends out of the body. A third instrument is advanced into contact with both the first instrument and the second instrument so as to position the first component and the second component in a predetermined position relative to one another. An instrument assembly for percutaneously implanting an orthopaedic assembly is also disclosed.

Abstract: Vertebra bodies in the human spine are stabilized through the use of minimally invasive surgery for the implantation of an elongate implant plate assembly having spaced first and second screw receiving socket elements which are configured for respective attachment to first and second spaced vertebra with the aid of bone fixation screws and these elements are slidably received with respect to each other for adjustably changing the distance between the screw receiving socket elements. A lock assembly is also provided for selectively locking the first and second screw receiving elements from further relative sliding.
