Key Benefits of the Simplify Trial

Why should I consider participating in the Simplify™ Disc Clinical Trial?

Simplify Disc may provide benefits over cervical fusion and over other currently available FDA-approved cervical artificial discs.

Key Benefits

Designed to provide up to 12 degrees of range of motion

  • Mobile bearing design may enable natural motion
  • Allows for motion created by the patient's own anatomy

Designed for MRI

  • Conventional cervical artificial discs are metallic and require CT scans to assess post-operatively
  • MRI is the ideal screening tool for cervical problems (Sundseth, Eur Spine J 2013)
  • Simplify Disc is the only cervical artificial disc composed of MRI-friendly materials (fig. 1), making it non-invasive and requiring no ionizing radiation from CTs

Radiation Safety

MRI vs. CT Scan: What’s the difference?

CT Scans and MRIs are imaging tools used to evaluate, diagnose and treat patients.

Metallic disc not visible in MRI

A CT Scan uses highly specialized X-ray equipment to produce its images. However, these X-rays expose patients to ionizing radiation, which may cause a small increase in a person’s lifetime risk of developing cancer (Linet, CA Cancer J. Clin 2012)

  • The average radiation dose in a cervical spine CT scan is equal to 400 chest X-rays (Linet, CA Cancer J. Clin 2012)
  • Conventional cervical artificial discs are metallic and require CT scans to assess post-operatively
  • CT myelograms may be required for follow up with metallic cervical implants - these are CT scans with a puncture to the spinal cord to inject contrast agent
  • Some patients have reactions to intravenous contrast dyes used in CT Scans which are used to improve visualization with CT imaging

Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body and is the preferred method for spine problems.

  • The metal in current metallic implants distorts the images produced in MRI.
  • MRI may not be appropriate for patients with metallic devices such as pacemakers or spinal stimulators.
  • However, an MRI is the preferred method for imaging soft tissue without the side effects.

Designed to eliminate the need for CT Scans

  • Simplify Disc design spares patients exposure to high-dose ionizing radiation from CT scans and potentially harmful side effects of contrast media injected directly into the spinal cord

Designed for widest range of patient sizes

  • Simplify™ Disc heights and footprint sizes are designed to match a broader range of patient anatomy
  • Average patient cervical disc height is 4.0mm, and most FDA-approved cervical artificial discs have minimum heights more than 5.5mm
  • Simplify™ Disc has the lowest disc height available (4.0mm)

Designed to eliminate Metal Wear

  • Simplify™ Disc is non-metallic, and the advanced materials are more biocompatible than materials in conventional cervical artificial discs
  • The Simplify™ Disc is built on a clinically successful design implanted in more than 2,000 patients worldwide.
