Abstract: A variable height vertebral body replacement implant used in corpectomy surgery to provide support in place of a removed or damaged vertebrae, and contain and compact bone graft material.

Abstract: A spinal cage system for inserting a spinal cage assembly into a spine to separate and support adjacent spinal vertebrae, includes a first cage member; a second cage member; and an articulating mechanism adapted to connect the first cage member to the second cage member and to permit the first and second cage members to move relate to each other. An insertion instrument is adapted to capture the spinal cage assembly for insertion of the spinal cage assembly into a spine and to rotate the first and second cage members relative to each other to achieve a desired orientation in the spine.

Abstract: The present invention describes an expandable vertebral implant and the method of use. The longitudinally expandable vertebral implant includes telescoping sections adapted for incremental expansion and ease of securement at any desired increment in situ, and constructed and arranged to engage opposing vertebrae, while simultaneously permitting easy insertion and removal of a similarly expandible top member.

Abstract: A cage to separate and support adjacent vertebrae in the spine that have undergone orthopedic spinal fusion procedures. The cage has first and second spacer members for insertion between adjacent vertebrae with a hinge located between the spacers. An advancing mechanism is located between the first and second spacer members that pivotally moves the first and second spacer members relative to each other at an angle which facilitates the insertion of the cage around the spinal cord. After insertion, the advancing mechanism is operable to position the first and second spacer members in the desired position between the two adjacent vertebrae.
