Abstract
A system, a method, and instruments for manipulating a surgical cord into spinal implants to assist in correcting a spinal deformity are described. The system may include a tensioner, a tensioner extension, and a counter tensioner. One of the instruments can include an elongate body, a dual coupler, and a nose member. The elongate body has a flexible cylindrical member adapted to carry tension along a longitudinal axis, where the flexible cylindrical member is sized to receive a surgical cord through a lumen within the flexible cylindrical member. The dual coupler is disposed on a proximal end of the elongate body, and include a bore for receiving a nose portion of a tensioner and for guiding the surgical cord into the tensioner. The nose member is disposed on a distal end of the elongate body, and be adapted to discharge the surgical cord from the elongate body.
