Abstract
The present application describes a pedicle fixation system and methods for correcting deformities of the spine and fixing the corrected portion of the spine in a corrected position. The disclosed system and associated methods include at least one pedicle screw in which a receiver portion of the pedicle screw is coupled to a screw portion of the pedicle screw in a manner such that the receiver portion is initially movable relative to the screw portion in a polyaxial fashion and subsequently lockable relative to the screw portion prior to locking a rod in the housing. Instruments for locking the receiver portion relative to the screw portion are also described.
