    摘要： The present invention is generally directed to a unique bone screw which, in one form, may be used to engage with and attach an implant to bone or bony tissue. In one embodiment, a bone screw includes an elongate shank extending along a longitudinal axis from an enlarged proximal head portion to a distal tip. The elongate shank includes a first portion having a first non-tapered, linear external profile and a second portion having a first tapered external profile that increases toward the proximal head portion. The second portion is positioned between the first portion and the head portion and terminates distally of the proximal head portion. In one form of this embodiment, the bone screw can be advanced through a passage of an implant such that an interference fit is provided between the bone screw and the implant.

    摘要： A system includes a sleeve including first and second arms each including an outer ramp and an inward projection, each of the arms defining a cavity. First and second extensions are configured for disposal in the cavities. A fastener includes walls defining an implant cavity and a distal portion. The walls each include first and second end surfaces and a locking cavity. The extensions are configured for translation relative to the sleeve between a first orientation such that the extensions engage the respective ramps to fix the projections with a respective locking cavity in a configuration to capture the fastener with the sleeve and a second orientation such that the extensions move out of engagement with the respective ramps so that the projections are movable out of engagement with the locking cavities to release the fastener from the sleeve. Methods of use are disclosed.

    摘要： A retaining mechanism for use in affixing a stratum to bone is disclosed. The retaining mechanism comprises a stratum, a retaining element and a spring element. The stratum comprising a first surface, a second surface, and a hole extending between the first surface and the second surface, wherein the second surface is configured to engage at least a portion of the bone. The retaining element comprises a first position that permits a fastener to be passed through the hole, and a second position that at least partially overlaps the hole. The spring element is configured to engage the stratum and configured to engage the retaining element such that the spring element helps maintain the retaining element in its second position so as to help prevent inadvertent backing out of the fastener after the fastener has been fully inserted into the hole.
