A spinal screw assembly is provided. The assembly may be provided with a screw and a movable head in which angulation of the screw relative to the movable head is constrained so that angulation within limits is allowed in one plane but lesser or no angulation is allowed in another plane. Methods to assemble the disclosed apparatus are also disclosed.

Apparatus and method for limiting a range of angular positions of a screw

An apparatus and method related to a collet for a spinal screw are described herein. In some embodiments, such an apparatus includes a screw, a movable head comprising a top portion and a bottom portion, a concave interior larger than a screw head, a connecting rod, a locking element screw, and a collet interposed between the screw head and the concave interior of the movable head, where the collet comprises a flexible hinge, and where the collet reduces axial compression force transferred from the set screw to the screw head.
