Distraction tools for distracting an interspinous space formed between spinous processes. The distraction tool may include first and second handles connected together at a pivot between first and second ends. First and second prongs may extend outward from the handles. The handles may move about the pivot between a first orientation with the first and second prongs in proximity to each other and a second orientation with the first and second prongs separated in a first direction. A third member may be connected to the first and second handles and include a third outwardly-extending prong. The third member may be positioned together with the first and second prongs to form a unified prong when the first and second handles are in the first orientation. The unified prong is sized and shaped for insertion into the interspinous space. The third prong may separate from the first and second prongs in a second direction when the first and second handles are in the second orientation. The prongs distract the interspinous space when the handles are in the second orientation.
