Abstract
A spinal fixation system for use in securing a spinal rod to a vertebra using a lockable bone screw connector. The connector is configured to be movably connected to the head of a bone screw, and a spinal rod can then be used to physically connect a first vertebra to a second vertebra. The spinal fixation system includes a tool grasping the connector by a locking and/or unlocking instrument that can allow the connector to lock to the bone screw by moving a collet, while the connector can still move along the spinal rod until locked into place by a set screw. The connector can be selectively unlocked from the bone screw for adjustment or removal.
