Motion-Preserving Artificial Disc Replacement

Clinical success rates exceed 95% with expert surgical technique and physical therapy.

For the right candidate, ADR offers distinct advantages over fusion. The most significant benefit is the preservation of motion, which theoretically reduces the stress transferred to the adjacent spinal segments, thereby lowering the risk of "adjacent segment disease" (premature wear and tear on neighboring discs). ADR also typically allows for a faster return to normal activities since there is no need to wait for bones to fuse.

Recovery is generally faster than with a spinal fusion. Most cervical ADR patients go home the same day or the next day, and lumbar ADR patients may stay 1 to 2 days. Because the implant is immediately stable, patients are encouraged to walk right away. Soft collars or braces are rarely needed. Most patients can return to light office work within 1 to 3 weeks and resume full, unrestricted activities (including sports) within 6 to 12 weeks.

Current data suggests that artificial discs are highly durable. Long-term studies tracking patients for 10 to 15 years show excellent implant survivorship, with very low rates of mechanical failure or the need for a revision surgery. However, because the technology is relatively newer than fusion, definitive 30-to-40-year data is still being gathered.

No. ADR is currently FDA-approved for specific levels in the cervical spine (C3 to C7) and the lumbar spine (L3 to S1). It is not performed in the thoracic (mid-back) spine, as the rib cage naturally limits motion in that area, making disc degeneration much less common and fusion highly effective when surgery is needed.
