Read the full statement (145 words)
The Surgical Titanium Mesh System is indicated for use in the thoracolumbar spine
(T1-L5) to replace a diseased vertebral body resected or excised for the treatment of
tumors, to achieve anterior decompression of the spinal cord and neural tissues, and to
restore the height of a collapsed vertebral body.
The Surgical Titanium Mesh System 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.
The Surgical Titanium Mesh System is intended for use with supplemental internal
fixation. The supplemental internal fixation systems that may be used with the Surgical
Titanium Mesh System include DePuy AcroMed titanium plate or rod systems (e.g.
Kaneda SR, University Plate, M-2, ISOLA, VSP, Moss Miami, TiMX and Profile).
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
