1. A system for stabilizing, reinforcing or repairing a fracture of a vertebral body including a pedicle, the system comprising:
an intravertebral implant comprising an anterior end element and a plate comprising a planar bearing surface;
a pedicle fixation coupled to the intravertebral implant and comprising a hollow sleeve defining a main axis, wherein the pedicle fixation is configured to be secured to the pedicle to control an insertion depth of the intravertebral implant within the vertebral body along the main axis; and
a central traction member movably disposed within the hollow sleeve of the pedicle fixation and configured to receive a pulling input to proximally translate the central traction member along the main axis to cause the anterior end element to be moved towards the pedicle fixation, thereby causing expansion of the intravertebral implant by the planar bearing surface being moved away from the main axis of the intravertebral implant in only a cranio-caudal expansion plane.
