  • Publication number: 20050049593
    Abstract: A fixation system includes a plate comprising a top surface, a bottom surface, a central longitudinal axis, at least one fixation hole extending between the top and bottom surfaces and comprising an undercut therein, and at least one passage intersecting one of the undercuts. At least one resilient clip is disposed in at least a portion of the undercut, with the at least one clip having a pair of generally parallel sides and an end tab. At least one fastener is provided and comprises a head and a threaded shaft, with the head comprising a perimetral groove extending around at least a portion thereof and an instrument receiving portion. The at least one clip is configured and dimensioned to seat in the undercut with the end tab extending within the passage, and the at least one fastener is configured and dimensioned to be received in the at least one fixation hole and securable therein when the at least one clip abuts the perimetral groove of the head.

  • Publication number: 20050015093
    Abstract: 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.
