Core Tip
Core Tip: Dynamic cervical implant (DCI) stabilization has been reported to have satisfactory clinical and radiological results with short- and mid-term follow-up in the treatment of cervical degenerative disc disease. This is a 5-year follow-up study to investigate long-term results of DCI arthroplasty. The results showed the patients’ clinical results were significantly improved at the last follow-up. The functional spinal unit lateral bending was limited, the segmental flexion-extension range of motion could be partially preserved, and the range of motion at adjacent level could be maintained after DCI arthroplasty. We believe that DCI arthroplasty is a safe and effective non-fusion technique to treat cervical degenerative disc disease.
