1. A system for manipulating an implant connected to a cord, the system comprising:
a counter tensioner to guide the cord from a tensioner into a head of an implant, comprising:
an elongate body with a proximal end and a distal end, the distal end including an implant interface that is releasably coupleable to the head of the implant thereby enabling translation of the implant relative to another implant implanted in an adjacent or nearby vertebrae; and
a handle at the proximal end of the elongate body, the handle configured to secure the implant interface to a proximal end of the head of the implant, wherein the handle includes a lock actuated relative to the handle to engage a locking mechanism configured to secure the implant interface on the distal end of the head of the implant, and wherein the locking mechanism includes a lock cylinder coupled to the lock in the handle.
