Abstract: An inserter for a bone screw assembly includes a hollow outer shaft with an inner shaft concentrically disposed therein. The distal ends of the inner shaft and outer shaft each define a feature for engaging the bone screw assembly. A collar is concentrically disposed about the proximal end of the inner shaft and a rotational interface is provided between the collar and inner shaft. The rotational interface is configured so that rotation of the collar relative to the inner shaft moves the collar into abutting engagement with a hub defined at the proximal end of the outer shaft. This abutting engagement locks the inner and outer shafts together when the distal ends of the shafts are engaged to the bone screw assembly for use in introducing the bone screw assembly into a bone.

Abstract: The present invention provides an attachment for an operating table preferably including two base portions adapted to rest on the frame of an operating table, a frame portion adapted to support a tray within the sterile field during surgery, and at least two support portions extending upwards from the first and second base portions, respectively, in order to support the frame portion.

Abstract: The present invention provides a device for cutting and placing a bone button during a button fusion procedure. The device preferably includes a first shaft portion, a second shaft portion rotatably disposed within said first shaft portion, and a cutting portion removably attached to said first shaft portion. When said first shaft portion is rotated, the cutting portion cuts a button of bone, which is then taken into an interior space of said cutting portion. Applying pressure to the second shaft portion forces the button of bone out of the device and into the proper location for a button fusion. The present invention also provides a method of using the device to perform a button fusion.
