Abstract: A device including first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force so as to urge the first and second plates away from one another, wherein the at least one mechanical actuation mechanism includes first and second actuation sub-mechanisms configured to provide first actuation and second sub-mechanism distraction forces that are antagonist to one another; wherein the device has a range of expansion ranging from a minimum distance to a maximum distance between the first plate and the second plate, and wherein the first actuation sub-mechanism distraction force and the second actuation sub-mechanism distraction force combine to provide the distraction force that is substantially constant.
