    摘要： An instrument for holding an intervertebral spacer, the instrument comprising a shaft having a proximal end and a distal end, the proximal end forming a handle and the distal end forming a spacer engaging subassembly, the spacer engaging subassembly comprising at least one selectively expanding and contracting enclosure into which at least a portion of the spacer is introduced when the engaging subassembly is expanded and an actuating mechanism, extending from the proximal end to the distal end, by which the spacer member engaging subassembly may be selectively expanded and contracted.

    摘要： An instrument for holding an intervertebral spacer includes a shaft having a proximal end forming a handle, and a distal end forming a claw subassembly for holding the spacer; the claw subassembly including a first pincer which is fixed at the distal end of the shaft and a second pincer which is selectively rotateable into and out of spacer holding association with said first pincer to hold and release, respectively, the spacer. The instrument includes an actuation mechanism for selectively rotating the second pincer, wherein the first and second pincers have opposing inner curved surfaces that extend to a distal end of the instrument.

    摘要： A trial spacer kit has a plurality of trial spacers of varying heights. Each spacer includes a disc having a top surface and a bottom surface defining a height of said spacer, an annular groove formed in said disc that defines a central trunk of said spacer, the central trunk extending between the top and bottom surfaces of said spacer, a first radial flange provided at an upper end of the central trunk and a second radial flange provided at a lower end of the central trunk. The annular grooves of the spacers have a common dimension. The radial flanges of a first one of the spacers is thicker than the radial flanges of a second one of the spacers so that the first one of the spacers has a greater height than the second one of the spacers.
