NCT01511445

Brief Summary

This study randomizes neck and arm pain patients being treated with discectomy and anterior interbody fusion into two groups: one to receive a new ceramic implant and a control group with a more traditional plastic implant. The study will measure and compare pain and disability improvement with the two products over a period of two years. The fusion status will also be judged with plane x-rays and one CT scan.

Outcome Measures

Primary Outcomes (1)

  • Neck Disability Index

    The change in the Neck Disability Index compared to the pre-op value for each group will be compared. Neck disability index is a unitless measure from zero (no disability) to 100 (absolute disability). Change is calculated as the pre-op value minus the 24 month value. A negative difference indicates that the patient is more disabled at 24 months.

    24 months post-op

Secondary Outcomes (1)

  • Fusion Status

    3 mo., 6mo., 12 mo., 24 months

Study Arms (2)

ACDF with PEEK interbody cage

ACTIVE COMPARATOR

Anterior cervical discectomy and fusion (ACDF) with an interbody spacer made from polyetheretherketone (PEEK) plastic. The open space in the center of the cage is to be filled with local autologous bone harvested during the decompression phase of the procedure.

Device: Anterior cervical discectomy and fusion (ACDF) with PEEK Cage

ACDF with Valeo CSC Ceramic Cage

EXPERIMENTAL

ACDF with the Valeo CSC cage, a silicon nitride ceramic interbody cage. The center area of the cage is filled with porous silicon nitride. No autologous bone is used; the cage is soaked in patient blood.

Device: Anterior cervical discectomy and fusion (ACDF) with a Valeo CSC Cage

Interventions

Also known as: Medicrea Manta or similar PEEK cage
