SynMesh
Fig 1: SynMesh system. The SynMesh system is indicated for use as a vertebral body replacement device in thoracolumbar spine (T1 through L5) to replace a collapsed, damaged, or unstable vertebral body due to tumor or trauma. This modular system allows building of the most appropriate construct to address the defect and patients anatomy. The SynMesh system is to be used with Synthes supplemental internal fixation systems, eg, VentroFix or USS.
This update features 36 additional mesh heights and additional instruments.
SynMesh: additional sizes (noncontoured and precontoured)
SynMesh is used for vertebral body replacement in the case of tumor or trauma from T1L5. Existing sizes are cut to fit in corpectomy sites, which increases OR time. Straight implants in longer vertebral body reconstructions can impinge posteriorly on the spinal cord because they do not follow the normal anatomy. Therefore, additional heights have been developed to reduce the need to cut down larger sizes and reduce OR time in these cases. The 10 mm diameter SynMesh is now available in heights of 14, 16, 20, 22, 24, and 32 mm, the 12 mm diameter in heights of 14, 16, 20, 22, and 24 mm, and the 15 mm diameter in heights of 18, 20, 22, and 24 mm. Contoured implants are offered to better fit the anatomy and reduce the likelihood of impingement on the spinal cord. They are available in diameters 12 mm, 15 mm, 17 x 22 mm, 22 x 28 mm, and 26 x 33 mm. The available heights for all diameters are 88 mm and 150 mm.
Fig 2: Synmesh - vertebral body replacement. Convex End Rings
The Convex End Rings enable locking the end ring to the mesh with the new low-profile 2.0 mm or 3.0 mm Locking Screw.

The Forked Impactors enable better maneuvering of the SynMesh construct into its final position. Three designs are available: angle lateral, angle superior, and straight.
Fig 4: Forked Impactors. Implant Holder, large and small with tips
The Implant Holder improves secure handling of the mesh and distributes the impaction forces over a larger area, reducing implant deformation during insertion.

The Insert Trimmer is to be used with SynCore, which are cancellous bone inserts, to fill the interior of the SynMesh Spacer. The inserts can be stacked and/or trimmed to the desired lengths.
