Intended Use

The Trabecular Metal Vertebral Body Replacement System is comprised of vertebral body replacement devices intended for use in the thoracolumbar spine (T1-L5) to replace a collapsed, damaged or unstable vertebral body due to tumor or trauma (i.e., fracture). The Trabecular Metal Vertebral Body Replacement is intended for use with supplemental internal spinal fixation systems. The Trabecular Metal Vertebral Body Replacement may be used with bone graft.

Device Story

Trabecular Metal Vertebral Body Replacement (VBR) System; porous tantalum deposited on vitreous carbon skeleton; replaces diseased/damaged vertebral bodies and adjacent discs in thoracolumbar spine (T1-L5). Used in spinal surgery by surgeons; requires supplemental internal spinal fixation. Provides structural support to collapsed/unstable vertebrae; facilitates fusion when used with bone graft. Available in multiple configurations to match patient anatomy.

Clinical Evidence

Bench testing only; mechanical performance testing and analyses conducted to demonstrate that the device meets predetermined requirements for structural integrity.

Technological Characteristics

Material: Trabecular Metal (porous tantalum on vitreous carbon skeleton). Form factor: Vertebral body replacement device in various configurations. Energy source: None (passive implant). Sterilization: Not specified.

Indications for Use

Indicated for patients requiring replacement of a collapsed, damaged, or unstable vertebral body in the thoracolumbar spine (T1-L5) resulting from tumor or trauma (fracture). Intended for use with supplemental internal spinal fixation and optional bone graft.

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.
