A61B 17/58

US Classification:

606 69

Abstract:

A bone plating system for fixating distal or proximal ends of long bones includes a bone plate having a head portion and a shaft portion, and a plurality of bone screws, at least one of which is a locking bone screw and at least one non-locking cancellous bone screw. The bone plate has a plurality of plate holes in the head portion and a plurality of plate holes in the shaft portion. The head portion or the shaft portion of the bone plate may have a plurality of threaded plate holes for engaging the at least one locking bone screw and at least one non-threaded plate hole for engaging the non-locking cancellous bone screw. The non-locking cancellous bone screw and the at least one non-threaded plate hole are configured and dimensioned to have a particularly useful dimensional relationship.

Assignee:

Wright Medical Technology Inc. - Arlington TN

International Classification:

A61B 17/04

US Classification:

606305, 606104

Abstract:

A snap-off surgical screw configured for threading into a bone of a patient using a driver member, comprising a shaft extension joined to a screw portion via a frangible connection. The frangible connection comprises at least one defect formed through an outer surface of the frangible connection. The defect is configured to promote selective separation of the shaft extension from the screw portion at the defect. A proximal end of the screw portion is preferably provided with a recess, and the frangible connection is preferably positioned in the recess to thereby configure the shaft extension to snap-off from the screw portion below the proximal end of the screw portion.

Inventors:

Chad J. Patterson - Port Washington WI, US
Jennifer M. Schneider - Germantown WI, US

Assignee:

Titan Spine LLC - Mequon WI

International Classification:

A61F 2/44

US Classification:

623 1716, 623 1711

Abstract:

An implant that has a predefined ratio of load bearing surface area to the overall size of the implant body and specifically to the surface area of a centrally located opening of a vertical aperture which connects to a center void area or passage defined by the implant body shape. This invention discloses a critical ratio or balance between loading of contained graft material through the hollow center or central passage of the implant and the implant's frictional load bearing or contact area with e. g. , adjacent vertebral bones. Application of this invention to a spinal implant provides an improved integration and integration rate of the graft material or the fusion of the adjacent vertebral bone structures. The ratio between implant load bearing surface area and implant central opening area maximizes implant internal volume and allows a large passage disposed medial laterally to allow for radiographic verification of fusion growth.

A61B 17/88

US Classification:

623 1716, 623 1711, 606100

Abstract:

An apparatus for distracting a disc space having an annulus. The apparatus includes a spinal implant having a pre-determined size sufficient to balance frictional fit in the disc space and elongation of the annulus. The implant has a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions defining a substantially hollow center and a single vertical aperture. At least one of the opposing anterior and posterior portions presents a substantially flat impact face including an opening with an instrument retention feature. The apparatus also includes a rasp, a plurality of distractors, and an instrument able to engage and manipulate the spinal implant, the rasp, and the plurality of distractors. The size-specific rasp is adapted to clear the disc space of all soft tissue and cartilage. The plurality of distractors have progressively increasing heights adapted to distract the disc space before use of the spinal implant.

US Classification:

623 1716, 623 1711, 606 90, 606100

Abstract:

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, a single vertical aperture, and a roughened surface topography on at least the top surface. The posterior portion has a generally rounded nose profile, and has a shorter height than the anterior portion such that the spinal implant comprises a lordotic angle for aligning the spine of a patient. The junctions of the top and bottom surfaces and the anterior portion comprise a sharp edge to resist expulsion of the spinal implant upon implantation.

International Classification:

A61F 2/44

US Classification:

623 1716, 623 1711, 606279

Abstract:

A method of using an interbody spinal implant by implanting the spinal implant into a patient in need of the spinal implant. The method includes accessing the disc space of the patient and locating the center of the disc space. The disc space is incised by making a window in the annulus of the disc space for insertion of the spinal implant. The endplates are cleaned of all cartilage and the disc structure, which is encapsulated by the annulus, is removed while avoiding damage to the endplate structure of the vertebrae. Optionally a size-specific rasp is selected and the disc space is cleared of all soft tissue and cartilage. Optionally the disc space is distracted by sequentially expanding it with distractors of progressively increasing heights. A spinal implant having a pre-determined size sufficient to balance frictional fit and elongation of the annulus is selected and seated in the disc space.

US Classification:

623 1716, 623 1711

Abstract:

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, and a substantially hollow center in communication with a vertical aperture, which are filled with a bone graft material. The dimensions, shape, and position of the vertical aperture facilitate contact between the bone graft material and vertebral endplate bone to support and enhance bone growth.
