Abstract:

BACKGROUND: Anterior cervical discectomy and fusion is an effective method for the operative treatment of cervical disease, but some problems appear in long-term clinical practice.
OBJECTIVE: To evaluate the security and availability of the dynamic cervical implant (DCI) used in the anterior cervical decompression non-fusion.
MATHODS: A total of 5 patients (6 segments) with cervical disease were treated by anterior decompression and replaced by DCI. The JOA score was evaluated preoperatively and 3 days, 3 and 6 months after surgery to observe the recovery of neurological function. Plain radiography was taken to survey the intervertebral space height and mobility.
RESULTS AND CONCLUSION: All cases were followed up for 1-6 months. JOA average score increased from 8.5 points to 15.4 points. The prosthesis curve was good. Replaced segment achieved stability and restored partial of normal rang of motion. Cervical stiffness and limitation of activity were not found. The implantation of DCI not only provides elastic dynamic stability, but also restores and sustains intervertebral space height and mobility. Besides, the short-term curative effect is satisfactory.
