Disclosed herein are spinal fixation systems that may comprise a screw, a body, and a pressure cap. A screw may comprise a head at a proximal end, a bone connection element at a distal end, and a first mating element disposed on a head of a pedicle screw. A body may comprise a proximal end, a distal end, a mounting rod receiving channel at a proximal end, and a screw head receiving aperture at a distal end. A portion of the mounting rod receiving channel may be operable to receive a compression element. A pressure cap may comprise a proximal end, distal end, and a second mating element on a distal end. A first mating element of the screw may be configured to mate with the second mating element of the pressure cap thereby limiting the pivotal movement of the screw to that of a monoaxial screw.

Convertible screw for spinal fixation

A modular head-to-head cross connector or construct extension system comprising a fastener element driven into a bone in a first orientation, a first U-shaped body operable to receive the fastener element and operable to receive a first rod in a first rod receiving channel, and a first compression element driven adjacent to and against the first rod in the first rod receiving channel, thereby engaging the first rod against the fastener element in a second orientation independent of the first orientation of the fastener element. The system further comprises a second U-shaped body operable to receive first compression element and operable to receive a second rod in a second rod receiving channel, and a second compression element driven adjacent to and against the second rod in the second rod receiving channel, thereby engaging the second rod against the first compression element in a third orientation independent of the second orientation.
