## Indications for use
The Theken VU VBR SYSTEM is indicated for use in the thoracolumbar spine (T1-5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma (e.g., fracture). The Theken VU VBR SYSTEM is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absences of fusion for a prolonged period. Bone graft material is recommended to be packed into the interior openings of the device prior to implantation. The Theken VU VBR SYSTEM is intended to be used with supplemental internal spinal fixation systems, such as the Theken BodyForm Thoracolumbar Fixation System (K983622, Approved 12/98) or the Theken Coral Pedicle Screw System (K041592, Approved 9/04).
