About ProDisc-C

 

The ProDisc-C Total Disc Replacement has been determined to be safe and effective in the treatment of intractable symptomatic cervical disc disease (SCDD) at one level from C3 to C7. The ProDisc-C Total Disc Replacement surgery is intended to:

 

  • Remove the diseased disc
  • Restore normal disc height
  • Decompress surrounding neural structures
  • Potentially provide motion in affected vertebral segment
  • Improve patient function

 

Design Philosophy

The ProDisc-C implant has been designed to maintain the physiologic range of motion in the spine. The implant was developed using the clinically proven ball and socket concept used in joint replacement implants for over 40 years. The ProDisc-C implant is composed of three components – two cobalt chrome alloy (CoCrMo) endplates and an ultra-high molecular weight polyethylene (UHMWPE) inlay and is inserted into the vertebral bodies en-bloc.

 

Ball and socket design

  • Controlled and predictable motion
  • Fixed center-of-rotation
  • Coupled motion: translation with rotation
  • Prevents anteroposterior shear to protect posterior anatomical structures

 

Secure fixation with zero profile

  • Patented central keel provides secure primary fixation
  • Plasma-sprayed titanium coating on bone contacting surfaces promotes bony on-growth
  • Implant does not contact anterior soft tissue structures after implantation

 

Anatomical Sizing

  • 18 anatomical sizes facilitate an accurate match with the patient’s anatomy
    • 6 footprints
    • 3 heights (5, 6 and 7 mm)

 

Safe and reproducible surgical technique

  • Three step implantation technique
  • Enables accurate sizing and precise placement of the implant

 

Streamlined instrumentation

  • Designed for standard transverse approach to the anterior cervical spine
  • Enables clear visualization into the disc space

 

Surgical Technique

Synthes has worked with leading spine surgeons from around the world to refine the ProDisc-C instrumentation and surgical technique in order to facilitate safe and reproducible implantation through a standard transverse approach to the anterior cervical spine.

 

The instrumentation has been engineered to enable precise placement and visualization of the implant. The ProDisc-C is implanted in three steps:

​1. Trial

​2. Keel Preparation

​3. Implant

​Milling ​Chiseling

Clinical Experience

A ProDisc-C IDE clinical study evaluated the ProDisc-C Total Disc Replacement surgery compared to anterior cervical discectomy and fusion (ACDF) surgery. The study demonstrated that ProDisc-C surgery is a safe and effective alternative to fusion surgery for qualified patients. For more information about the ProDisc-C IDE Study, refer to the ProDisc-C IDE Study Brochure. Published peer-reviewed articles are also available upon request.
