The Surgical Titanium mesh is also indicated for treating fractures of the thoracic and lumbar spine. The Surgical Titanium Mesh System is designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period. It is recommended to pack bone graft material inside the mesh cage prior to implantation. The Surgical Titanium Mesh System is intended for use with supplemental internal fixation. The supplemental internal fixation system that may be used with the Surgical Titanium Mesh System is the Blackstone Medical Spinal Fixation System. ## Device Story Spinal vertebral body replacement device; hollow cylindrical titanium mesh tube with diamond-shaped perforations; allows bone graft packing for fusion; includes angled end rings with exterior spikes to prevent lateral movement; implanted by surgeons in clinical/OR settings; restores biomechanical integrity of spinal column; used with supplemental internal fixation system; provides structural support for collapsed vertebrae or post-resection/excision of tumors. ## Clinical Evidence No clinical data provided; substantial equivalence based on design and material characteristics. ## Technological Characteristics Hollow cylindrical tube made of commercially pure titanium (ASTM F-67); end rings and screws made of titanium alloy (6AL-4V ELI, ASTM F136); perforated walls; angled end rings with spikes; mechanical device; no software or energy source. ## Regulatory 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. ## Predicate Devices - Blackstone Surgical Titanium Mesh System ([K030744](/device/K030744.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Equivalent Device: | Blackstone Surgical Titanium Mesh System (K030744) | ### Device Description: The Blackstone Medical, Inc. Surgical Titanium Mesh System is comprised of a hollow cylindrical tube made from commercially pure (CP) titanium conforming to ASTM F-67. The walls of the tube are perforated with evenly spaced diamond-shaped openings. These openings and the hollow core allow grafting material to be placed inside the device to help achieve solid fusion. Because of the construction, the angle and the length of the mesh can be reduced incrementally to adjust it to individual anatomical conditions. The end rings, standard ring and screws of the device are made of titanium alloy (6AL-4V ELI, per ASTM F136). The end rings, which are placed onto each end of the tube, feature spikes on the exterior sides that help prevent lateral movement of the device. {1}------------------------------------------------ K030707 V61 2/2 Premarket Notification 510(k) Blackstone Medical, Inc.
