A device for supporting and/or assisting in bone fusion, particularly in the spine, is described. A plate member is provided, along with two or more attachment members that are anchorable to bones. In one embodiment, the plate member has a slot near one end and an aperture at another end. The attachment members include threaded posts for connection to the plate member via the latter's slot(s) and aperture(s). Alternatively, attachment members need not have a threaded post, and attachment members may be connected to the plate member via a bone bolt or similar fixation member. The slot(s) allow a single plate member to be used for a variety of operative situations and anatomies. A device for repositioning bones and a method for using the disclosed devices is also described.
