Project ID: D2009-32
Invention novelty:
Open design, variable height corpectomy cage may be secured and released once implanted, and features expandable mesh material into which bone graft material may be packed.
Value proposition:
· Four variable length telescoping titanium rods may be straight or curved to fit the area of the spine that is being repaired.
· Ratcheting mechanism allows the telescoping rods to be varied in length in finite increments.
· May be secured by serrations and released once implanted
· Set screws are provided to lock the telescoping rod in the desired position once the appropriate spacing has been achieved between the adjacent vertebrae
· Expandable titanium mesh material forms a tubular cage into which bone or bone graft material is packed
· After bone graft material is packed into the cage, a fourth lateral mesh wall is attached to the open side of the cage to form a completely contained cage structure.
· End rings may be ovoid, trapezoid or other generally four sided shapes may be utilized to efficiently match the removed vertebrae.
Applications:
Corpectomy cage provides support in place of removed or damaged vertebrae.
