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. In one embodiment, the capture device includes a fixed piece extending from the brace and a slidable piece associated with the fixed piece. A fastener can be rotated to pinch the binder between the slidable piece and a wall of the brace, securing the binder. A physician need not know the length of the binder prior to implantation, reducing the time required to perform a procedure.

         10 . A method, comprising: 
 inserting an elongated member into a patient's body through an incision in the body;    disposing, after the inserting, the elongated member substantially around a pair of adjacent spinous processes; and    actuating, after the disposing, a tool through the incision to couple a first end portion of the elongated member to a second end portion of the elongated member.    
     
     
         11 . The method of  claim 10 , further comprising: 
 adjusting, before the actuating, a length of the elongated member substantially around the pair of adjacent spinous processes such that an amount of flexion associated with the pair of adjacent spinous processes is limited.    
     
     
         12 . The method of  claim 10 , further comprising: 
 adjusting, before the actuating, a tension of the elongated member substantially around the pair of adjacent spinous processes such that an amount of flexion associated with the pair of adjacent spinous processes is limited.
