Disc Replacement
Total Disc Replacement (TDR) may be a solution for some patients with degenerative disc disease as an alternative to spinal fusion—providing the possibility for motion in the affected area.

ABOUT prodisc
prodisc® is a Total Disc Replacement (TDR) technology platform that offers a surgical treatment proven to maintain spinal balance and motion, decelerate adjacent level reoperations, and accelerate the return to normal activities.
It is the only total disc replacement system in the U.S. approved for two-level use in the lumbar spine
Centinel Spine is currently the only company in the United States to offer Total Disc Replacement devices for both the cervical and lumbar artificial disc replacement:
- prodisc® L: Total Disc Replacement for the lower (lumbar) spine (L3-S1)
- prodisc® C: Total Disc Replacement for the upper (cervical) spine (C3-C7)

prodisc® DESIGN
The prodisc design is based on two critical principles: a mechanism of action & post-operative fixation.
Mechanism of Action
The prodisc® implant is a ball and socket design with a fixed center of rotation. This patented design has been in clinical use since 1990 and utilized across the entire product platform. The fixed center of rotation allows physiological range of motion while providing stability to the spine and significantly reducing reoperations at the adjacent levels.
Fixation
Immediate Post-Operative Fixation
Immediate post-operative fixation is provided by the midline keels, ensuring the implant is securely held in place so the patient can begin rehabilitation and return to their normal activities as soon as possible.
Long-Term Fixation
The entire surface of the implant that is in contact with the vertebra is coated with a highly porous plasma sprayed titanium coating. This allows for bony on-growth into the porous surface of the implant for long term, secure fixation.
prodisc® OBJECTIVES
prodisc® was developed with several specific patient care objectives in mind:
- Maintaining Spinal Motion
- Reducing Adjacent Level Disease
- Resuming Activities of Daily Living
Degenerative disc disease can destabilize your spine. In order to protect adjacent segments of the spine from diseased segments, prodisc® is designed with a fixed center of motion, enabling translation only with bending motion.
Controlled & Predictable Motion
Unlike other designs, prodisc is designed to enable physiologic motion in the degenerated spine.
Range of Motion
prodisc allows a normal range of motion while providing stability through controlled translation.
The ‘gold standard’ for treating degenerative disc disease is to conduct a fusion and fuse the joint. However, immobilizing a segment of the spine has been shown to increase the rate of adjacent level degeneration. prodisc has been shown in multiple long-term studies to decrease the development of adjacent level disease.3
Range of Motion
Long-term prospective randomized multi-center evidence illustrated patients retained range of motion of 8.12° at 7 years.3
Degenerative disc disease can be very painful, and recovery from spinal surgery can take time. Special care has been taken to design prodisc to minimize the recovery associated with the procedure. In a study comparing prodisc and fusion, surgeons found that patients that received the fusion treatment option lost nearly twice as much blood during the procedure, spent nearly twice as much time in the OR, and had longer hospital stays.
Patented Midline Keel
- The prodisc keel is specifically designed to provide immediate stability, making post-op bracing optional.
- A study on military personnel (over 50% of the participants were Navy SEALs) found that 83% returned to active duty after receiving a prodisc L versus 67% that had received an ALIF.4

prodisc® STUDIES
No other disc replacement system has been studied more than prodisc®.
With more than 540 published papers, reporting on experiences with over 13,000 patients, the clinical data for prodisc strongly supports its safety and effectiveness. Here are just a few key takeaways from these numerous clinical studies:
-
4xFewer Reoperations
After 7 Years with prodisc C® vs. Patients that Received a Fusion (ACDF)3 -
4xLess Likely Adjacent Level Degeneration
After 5 Years with prodisc L vs. Patients that Received a Fusion (ALIF)5 -
LowerChange in Range of Motion
