    摘要: A drill guide, drill guide system and method of use is disclosed. The drill guide assembly includes one or more alignment drill tubes that are remotely alignable with corresponding fastener holes of a bone plate to which the drill guide is releasably lockable. The drill guide is configured to allow a bone hole to be drilled slightly off-center with respect to the fastener holes of the plate so that fasteners inserted in those holes may be used to compress the underlying bone segments together when the fasteners are tightened in the bone and plate. In one embodiment, the drill guide is disclosed for use in compressing and fixing adjacent vertebra as part of a spinal fusion procedure.

    摘要: Translational bone fixation assemblies, kits containing such assemblies, and methods of use are described herein. The described assemblies may be used in spinal fusion procedures in which a damaged or diseased disc (or part of a disc) is removed from between a pair of vertebrae and a spinal fusion spacer is placed between the vertebrae. The assemblies may be applied to an anterior portion of the affected vertebrae to span the affected disc space, and may be fixed to the vertebrae using bone screws. The assemblies may function to maintain the vertebrae aligned during the initial period following fixation in which fusion of the spacer to the adjacent vertebrae occurs. The assemblies may also function to share some of the axial spinal load applied to the fusion spacer to prevent extreme subsidence of the spacer into the vertebral body, such as where the patient has poor bone quality. The assemblies may also act to prevent the spacer from being expelled from the disc space during the initial post-operative period. Finally, these assemblies may be used in other parts of the body where the advantages of the assemblies are desired or applicable.

    摘要: An apparatus includes a bone fastener, a bone fixation device and a bone fastener retainer device. The head of the fastener has a convex lower surface with a first arcuate contour, and has a convex upper surface with a second arcuate contour. The fixation device is configured to receive the fastener in an installed position in which the convex lower surface of the fastener head rests on a concave surface of the bone fixation device that also has the first arcuate contour. Additionally, the retainer device is configured to be mounted on the fixation device in a position in which a concave surface of the retainer device overlies the convex upper surface of the fastener head. The concave surface of the retainer device also has the second arcuate contour. The bone fastener retainer device may be receivable over the fixation device in a mechanical interlock with the fixation device.

    摘要: The present invention provides a simplified bone fastener removal tool which allows the surgeon to remove bone screws or other bone fasteners from bone, and from bone plates incorporating fastener locking elements. The tool includes an inner shaft which axially engages the bone fastener, a drive shaft which allows the fastener to be rotated using the tool, and an internally threaded outer sleeve which, in combination with the drive shaft, allows for a controlled removal of the fastener from the bone plate and bone. In particular, the internal threads of the outer sleeve engage external threads on the drive shaft, such that rotating the drive shaft while maintaining the outer sleeve fixed causes the drive shaft to translate with respect to the sleeve. Thus, when a fastener is axially engaged with the drive shaft, a controlled removal of the fastener from the bone and bone plate is accomplished simply by rotating the drive shaft with respect to the outer sleeve. No pulling on the fastener is necessary. A method of using the tool is also provided.
