Abstract
A reduction system and method is disclosed for reducing a displaced vertebra between adjacent vertebrae. The system can include an anchor 60 placed in the displaced vertebra 70b, a cable 11 attached to the anchor 60 and a clamping member 50 which can selectively engage or disengage the cable 11 to maintain its position. The clamping member can be seated in a rod connector 58 attached to a rod 80 running along the longitudinal axis of the spinal column. A tensioning force can be applied to the cable 11 to pull vertebra 70b toward the rod 80. Once the vertebra 70b is pulled into the desired position, the anchor can be secured to the rod to maintain the position of the vertebra and the reduction apparatus is removed.
