Abstract

Systems in accordance with embodiments of the present invention can include an implant comprising a spacer for defining a minimum space between adjacent spinous processes, a distraction guide for piercing and distracting an interspinous ligament during implantation, and a binder for limiting or preventing flexion motion of the targeted motion segment. The binder can be secured to a brace associated with the implant during implantation by a capture device. A binder aligner aligns the binder with the implant stabilizing the implant, binder and the adjacent vertebrae.
