International Classification:

A61B 17/70

US Classification:

606257, 606259, 606267

Abstract:

Various methods and devices are provided for a facet replacement device. In one embodiment of the invention, a facet replacement device is provided and includes an elongate member matable to a first vertebra and a housing. The housing can have a connector formed thereon and matable to an adjacent second vertebra and an inner lumen formed therein. The housing can also include a deformable member disposed within the inner lumen and having an opening formed therein for slidably receiving at least a portion of the elongate member such that the elongate member can be angularly oriented relative to a longitudinal axis of the lumen.

International Classification:

A61B 17/70

US Classification:

606 86A, 606249, 606263, 623 1716

Abstract:

Various exemplary instruments for introducing an implant using a posterolateral approach are also provided, as well as various exemplary methods for using such instruments. In general, the instruments are configured to interconnect to an implant and/or to a guide member such that the components are all docked relative to one another. This allows the various components of a multi-piece implant to be mated intraoperatively within the disc space, and in particular to be guided into alignment with one another.

US Classification:

606258, 606257, 606264, 606267

Abstract:

A multi-level spine stabilization system comprises a plurality of securing members configured for attachment to a plurality of vertebrae. A plurality of adjustable rods segments extend between the plurality of securing members. The adjustable rod comprises a first rod segment that engages a second rod segment in an adjustable relationship. The length of the rod may be adjusted by moving the first rod segment relative to the second rod segment. For example, the first rod segment may be in a slideable relationship with the second rod segment such that sliding the first rod segment relative to the second rod segment results in a change in the length of the rod. In one embodiment, portions of both the first rod segment and the second rod segment are positioned within and secured to the securing member. Advantageously, the multi-level spine stabilization system described herein may be used to center dynamic portions of the rod between securing members.

Assignee:

DEPUY SPINE SARL - Le Locle

International Classification:

A61F 2/30

US Classification:

606069000

Abstract:

Disclosed herein are spinal fixation devices and tools for implanting the same. In one embodiment, an implantable spinal fixation plate and a guide device are provided and they include features that allow the two devices to removably mate to one another. As a result, the guide device can be used to position and hold the plate against bone while inserting drills, taps, awls, and other bone preparation devices through the guide device. The guide device can also be configured to allow fasteners to be inserted therethrough and into bone to attach the plate to bone.

International Classification:

A61B 17/58

US Classification:

606072000

Abstract:

A bone anchoring device for securing suture or cable within a bone hole of a bone includes an anchor member and a cable. The anchor member includes engagement ribs and an axial cutout. The axial cutout further includes a cutout surface and at least one pin that extends radially outward from the cutout surface. The cable is secured to the anchor member by penetrating the cable with the pins that extend radially from the axial cutout surface, such that the cable distal end aligns with the anchor distal end and that the cable proximal end extends beyond the anchor proximal end. This results in a bone anchoring device in which failure due to low pullout strength of the cable is greatly minimized or eliminated.
