3 and 4-year M6-C data is out — what spine surgeons should know

Spinal Tech

Orthofix has released three- and four-year preliminary outcomes from its M6-C artificial cervical disc single-level clinical trial.

What you should know:

1. Patients treated with M6-C "continue to have statistically significant benefits at three and four years" compared to anterior cervical discectomy and fusion patients, Frank Phillips, MD, an investigator in the study, said in a May 11 news release. "This is important as it demonstrates the positive results originally reported in the study have been maintained through four years."

2. At three years, M6-C patients had a mean Neck Disability Index score of 10.9, compared to 17.2 in the ACDF group.

3. The mean Neck Disability Index for M6-C patients at four years was 10.3, compared to 19.2 for the ACDF cohort.

4. A greater percentage of M6-C disc patients experienced an improvement in Neck Disability Index scores at three and four years compared to the ACDF group. Four-year results were significantly better for the M6-C group.

5. One removal was reported in the M6-C group within the first four years post-surgery, compared to three in the ACDF group.

6. Five-year data is being collected.
