Patent ID: 11998245

Abstract:
Systems and methods for treating a vertebral body. An intravertebral implant includes an anterior end element and a plate comprising a planar bearing surface. The plate may be exactly two plates movable in only a cranio-caudal expansion plane. A pedicle fixation is coupled to the intravertebral implant and includes a hollow sleeve. The pedicle fixation is configured to be secured to the pedicle to control an insertion depth of the intravertebral implant within the vertebral body. A central traction member is movably disposed within the hollow sleeve of the pedicle fixation to deploy the planar bearing surface(s). The central traction member may be rotatable within the hollow sleeve. An expansion instrument may move the central traction member relative to the pedicle fixation. The intravertebral implant may be locked relative to the pedicle fixation in six degrees of freedom.
