Choosing A Cervical Artificial Disc

Choosing the Right Cervical Artificial Disc – Mobi-C vs. ProDisc-C:  

Disc replacement is a surgical procedure designed to address degenerative disc disease and herniated discs in the neck, where damaged discs are replaced with artificial ones to maintain spinal mobility and alleviate pressure on nerves. Also, this approach contrasts with traditional spinal fusion by preserving natural motion, which can lead to better long-term outcomes for patients. Among the most widely used devices, Mobi-C stands out for its mobile core design, which mimics the flexibility of a natural disc through a polyethylene insert that allows for multidirectional movement. Additionally, the Mobi-C is particularly effective for younger patients or those with active lifestyles, as it helps reduce the risk of adjacent segment degeneration by closely replicating the spine’s biomechanics.

In comparison, ProDisc-C features a fixed-center design with a metal-on-polyethylene articulation, providing stable motion while prioritizing durability and precise alignment. In addition, this device is often chosen for patients with specific anatomical needs, such as those requiring a more constrained range of motion to prevent instability. Furthermore, clinical applications for ProDisc-C include single-level replacements and cases where bone quality is a concern, with studies showing its reliability in maintaining disc height and reducing pain over time. Finally, both devices have transformed spine care, but the choice between Mobi-C and ProDisc-C ultimately depends on factors like the patient’s age, activity level, and the surgeon’s assessment of the spine’s condition.

What is the Mobi-C Disc?

The Mobi-C artificial disc is a mobile-bearing implant that allows a greater range of motion.

Key Features:

• Designed to move more naturally within the disc space
• Allows translation (sliding motion)
• FDA-approved for one-level and two-level disc replacement
• May better mimic natural spinal mechanics

What is the ProDisc-C?

The ProDisc-C is a fixed-core implant designed for stability and controlled motion.

Key Features:

• Ball-and-socket design
• Provides consistent and predictable motion
• FDA-approved for single-level disc replacement
• Long track record of clinical success

Mobi-C vs. ProDisc-C: Key Differences

Which Artificial Cervical Disc is Better?

There is no single “best” disc for every patient.

The choice depends on:

• Number of levels involved
• Patient anatomy
• Degree of degeneration
• Surgeon experience and preference

The most important factor is proper patient selection and surgical expertise.

Benefits of Cervical Disc Replacement Devices

Both Mobi-C and ProDisc-C offer:

• Preservation of motion
• Relief of nerve compression
• Reduced risk of adjacent segment disease
• Improved quality of life
