View Edit Delete	FLO-5PROV	Those of skill in the art will recognize that a variety of designs may be used for the screw member 118. For example, in one embodiment, the screw member 118 may include no head 238 and instead include threads on both ends of the shank 236. The threads on opposite ends of the shank may be traverse the shank 236 in opposite directions about the axis 246 such that rotation of the screw member 118 in one direction about the axis 246 draws the proximal wedge 114 and distal wedge 116 together and rotation of the screw member 118 in one direction about the axis 246 moves the proximal wedge 114 and distal wedge 116 away from each other.	59	Added by DJM 2 2021	2/18/21, 12:00 AM
