Artificial Cervical Disc Replacement: Initial Experience with 11 Cases

ABSTRACT

Background: Artificial cervical disc replacement after anterior decompression is considered a growing alternate to anterior cervical fusion. Objective: The aim of this study is to evaluate the clinical outcome and the efficacy of artificial cervical disc replacement in selected cases of cervical degenerative disc disease. Methods: This prospective series included 11 patients with one or more level cervical disc disease; 9 males and 2 females, their mean age was 39.4 years. All cases were operated upon in Neurosurgery Department, National Defense hospitals from 2009 to 2012. All patients were evaluated pre-operatively clinically and radiologically. They all received anterior cervical discectomy with artificial cervical disc replacement. Clinical outcome was assessed by the visual analogue scale (VAS). Motion preservation was followed radiologically at 3, 6 and 12, 18 months post-operatively. Results: Ten patients had been operated upon by anterior cervical discectomy with artificial cervical disc replacement in one level and double level surgery in one case only. All patients showed significant improvement in the preoperative VAS (p< 0.001). By the end of the study, there was radio-graphic evidence that motion was preserved at the treated as well as the adjacent levels. Conclusions: Artificial cervical disc replacement preserves motion at operated level and normal motion at adjacent levels and achieve improved functional outcome. It seems to be a satisfying alternative for cervical fusion. [Egypt J Neurol Psychiat Neurosurg.  2015; 52(1): 9-14]
