The Prodisc-C total disc replacement has been determined to be safe and effective in the treatment of symptomatic cervical degenerative disc disease. The Prodisc-C total disc replacement surgery is intended to:
– | Remove the diseased disc |
| – | Decompress the neurological structures |
| – | Restore normal disc height |
| – | Preserve motion in affected vertebral segment |
| – | Improve patient function |
Since December 2007 the Prodisc-C total disc replacement is approved for use in the US by the FDA after an IDE clinical study.
Design Philosophy
The Prodisc-C implant has been designed to maintain the physiological range of motion in the cervical 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.
The key features of the Prodisc-C design philosophy are:
Ball and socket design
| – | Semi-constrained design provides a fixed center of rotation |
| – | Designed to allow controlled dynamic motion through the physiological range of motion |
| – | Designed to prevent pure translational motion to theoretically protect the facets from excessive shear loading |
Secure fixation
| – | Patented central keel provide secure primary fixation |
| – | Plasma sprayed titanium coating promotes bony on growth |
Modular implant components
Different anatomical combinations facilitate accurate match with the patient’s anatomy
| – | 6 different footprints: - Medium and medium “deep” (same width with 2 mm more in depth) - Large and large “deep” - Extralarge and extralarge “deep” |
| – | 3 different heights: 5, 6 and 7 mm heights |
Safe and reproducible surgical technique
| – | Three-step implantation technique |
| – | Enables accurate sizing and placement of the implant |
Straightforward instrumentation
| – | Designed for standard anterior approach |
| – | Enables clear visualization into the disc space |
| – | Limits distraction forces on surrounding anatomical structures |
