Abstract

The screw assembly includes a screw, an insert, and a body member. The screw includes a longitudinal axis and a proximal end with a head portion and a distal end with a threaded portion. The insert operably couples with the head portion and is configured to rotate relative to the head portion about the longitudinal axis. The body member operably couples with the insert and is configured to pivot relative to the insert in a single plane parallel to the longitudinal axis. In other features, the body member operably couples with the insert and is configured to pivot relative to the insert about a transverse axis normal to a plane parallel to the longitudinal axis.
