Abstract
A system for correcting a spinal deformity includes an implant fixed to one side of a vertebra and a rod extending along an axis of the spine on a second side of the vertebra. An adjustment member, which may include a reel, is coupled to the rod. A force directing member, such as a cable, extends between the rod and the adjustment member. The force directing member is retractable toward and extendible from the adjustment member. A method of correcting spinal deformity includes providing an implant, a rod, an adjustment member coupled to the rod, and a force directing member extending between the rod and the adjustment member. The adjustment member can be retractable toward and extendible from the adjustment member.
