A new study published in Clinical Spine Surgery examines the M6-C cervical disc in primary and secondary surgeries. The researchers examined 33 patients who underwent spine surgery with the M6-C cervical disc and followed those patients for 17.1 months on average. There were nine patients with a history of cervical interventions.
The M-6 prosthesis is a new generation of the unconstrained implants; it was developed for better segmental biomechanics restoration. The implant doesn't rely on a ball-and-socket type design.
Here are five key findings from the report:
1. The Neck Disability Index, Visual Analog Scale and SF-36 results were better among patients who underwent primary surgery than the secondary surgery patients.
2. Nearly all — 87.5 percent — of the primary surgery patients reported good or excellent results after surgery.
3. Ninety-one percent of the primary surgery patients said they would have the procedure again.
4. There were four device-related complications and all occurred within the patients who underwent secondary surgery.
5. The researchers concluded, "The M6-C prosthesis appears to be a valuable addition to the CDA armamentarium. It generates very good results in patients undergoing primary surgery, although its use in secondary surgery should be avoided."
