Abstract
A polyaxial screw system includes a drive cap having a partition wall with a first side and an opposing second side, a passage extending through the partition wall. A sleeve projects from the second side of the partition wall, the sleeve and partition wall bounding a socket. A shaft outwardly projects from the first side of the partition wall. A screw has a threaded portion and a head formed on an end thereof. The head of the screw is at least partially disposed within socket of the drive cap. A collet is at least partially disposed within the socket of the drive cap. At least a portion of a compression cap movably extends through the opening in the partition wall so that the compression cap can selectively move the collet relative to the drive cap.
