摘要:
A pedicle screw fixation system and method for use of the same are disclosed. In one embodiment, a tulip is provided for holding a head of a pedicle screw substantially along a longitudinal axis. The tulip includes opposing first and second U-shaped receiving slots aligned along a transverse axis. A rod is received by the opposing first and second U-shaped receiving slots. A coupling collar includes a plurality of resilient fingers circumferentially disposed therearound such that a snap fit engagement with the head of the pedicle screw formed. The coupling collar includes a first deformable face operable for contact with the rod. A set screw is for adapted for driving engagement through the tulip along the longitudinal axis such that a second deformable face is positioned for contact with the rod. The first and second deformable faces conform to the shape of the rod in response to forceful engagement therewith.
