Abstract
A spinal fixation device includes a coupling, a pedicle screw, and a collet. The coupling has an opening extending therethrough. The pedicle screw has a head mounted to a shank that is positionable within a first vertebral body. The collet is receivable in the opening of the coupling and engagable with the head of the pedicle screw. The collet is selectively positionable between a first position and a second position where the collet engages a spinal rod and prevents one or both of axial and rotational movement of the spinal rod. The collet is adapted to facilitate the connection of the spinal rod to a second vertebral body. The collet defines a saddle having one or more locking features for engaging the spinal rod.
