Abstract: Expandable vertebral body implants, systems, instruments, and methods of assembly and using the implants, systems, and instruments are disclosed. The vertebral body implant includes a body with a first end and a second end, a first rotating member rotatably coupled to the first end, wherein an end includes a plurality of first notches inset into the first rotating member, a second rotating member rotatably coupled to the second end, wherein an end includes a plurality of second notches inset into the second rotating member, a first extension member moveably coupled to the first end, and a second extension member moveably coupled to the second end. The expandable cage system comprises a vertebral body implant and an insertion instrument. Methods for assembling and using the vertebral body implants and instruments are also disclosed.

Abstract: The present invention provides expandable devices and insertion tools for deploying the expandable devices. The expandable devices are capable of increasing in height and width when expanded from a closed configuration to an open configuration to occupy a larger volume and to present a larger surface area. The expandable devices are lockable and are capable of rigidly occupying a space after expansion. In some embodiments, the expandable devices are useful as interbody devices for spinal fusions.

Abstract: The present invention provides decorticating screws and insertion tools for implanting the decorticating screws. The screws anchor into a first and a second bone to fuse the two bones together. The screws include a rotatable bladed section to decorticate a joint space between the first and second bone. The screws also optionally include a cap to secure the screws in the bone and apply compression to the joint to be fused. In some embodiments, the decorticating screws are useful for sacroiliac (SI) joint fusion.
