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.
Few reports about the clinical and radiological outcome with more than 5-year follow-up exist.
This is a 5-year follow-up study to investigate the long-term clinical and radiological results of DCI arthroplasty.
A total of 40 patients who received DCI arthroplasty were consecutively reviewed from May 2010 to August 2015. The clinical results and radiological outcomes were retrospectively analyzed.
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. At the last follow-up, 12 (26.1%) segments developed heterotopic ossification.
DCI arthroplasty is a safe and effective non-fusion technique to treat cervical degenerative disc disease in long-term follow-up.
In the future, we hope to conduct multicenter randomized controlled trials to compare the DCI implantation and cervical disc replacement with regard to clinical and radiological results.
