The aims of the ARCH Fixation System are to:

• Maintain an expanded spinal canal
• Secure spinal stability
• Preserve the protective function of the spine after a laminoplasty has been performed

Indications

The Synthes ARCH Fixation System is intended for use in the lower cervical and upper thoracic spine (C3–T3) after a laminoplasty has been performed. The ARCH Fixation System holds or buttresses the allograft in place in order to prevent the allograft from expulsion or impinging on the spinal cord.

Contraindications

The ARCH Fixation System is not to be used:

• For screw attachment or fixation to the posterior elements of the lumbar spine
• For single- or two-level spondylosis without developmental spinal canal stenosis
• Under any direct load bearing conditions

The ARCH Fixation System is not to be used when there is:

• Focal anterior compression
• Isolated radiculopathy
• Loss of anterior column support resulting from tumor, trauma, or infection

The ARCH Fixation System must always be used with:

• Structural allograft
