A surgical implant device (310) that controls the relative movement between a first bone or tissue portion and a second bone or tissue portion. The device has a first connector member (340) connected for movement with the first bone or tissue portion and a second connector member (360) connected for movement with the second bone or tissue portion. A biasing member (388) pivotally connects the first connector member to the second connector member and resists the relative rotation between the first connector member and the second connector member.
