A method includes moving a spinal implant such that a central portion of the spinal implant is disposed between adjacent spinous processes, radially extending a proximal portion of the spinal implant on a first side of the adjacent spinous processes such that movement of the proximal portion between the adjacent spinous processes is inhibited, and radially extending a distal portion of the spinal implant on a second side of the adjacent spinous processes opposite the first side such that movement of the distal portion between the adjacent spinous processes is inhibited.
