Abstract

Background: Cervical radiculopathy occurs when a herniated disc cause pressure on a nerve root, resulting in dysfunction of the sensory, motor, or reflex pathways served by that nerve root. This trial aimed to evaluate the effectiveness of a dynamic cervical implant against a cervical interbody cage fusion for the treatment of a single degenerative disc in the cervical spine. Methods: This prospective randomized trial was carried out on 30 patients aged from 30 to 50 years old, both sexes, suffering from single degenerative cervical discs who were surgically treated by anterior cervical discectomy, intervertebral disc herniation from C3 to C7. Participants were split into two groups of equal size: those who would have a dynamic cervical implant (DCI) also received an anterior cervical discectomy and cage interbody fusion. In addition, those who would receive a cervical cage fusion also received an anterior cervical discectomy and a dynamic cervical implant. Results: Postoperative x-ray showed no adjacent segment disorder in 14 patients (93.3%) in the DCI group and 13 patients (86.7%) in the cervical cage fusion group without a statistically significant difference between groups. In the DCI and cervical cage fusion groups, the prognosis was 46.7%, 46.7% good, 40%, 26.7% excellent, 13.7% poor, 20% poor, and 0, 6.7% fair, respectively. Conclusions: In the treatment of cervical disc disease, the DCI shows promise as a potential alternative to total disc replacement and anterior cervical discectomy and fusion. The DCI has the ability to maintain device-level motion as well as minimize the development of adjacent segment disease. Additionally, the DCI protects the facet joints from the excessive stresses that are observed with other motion-preserving devices during lateral bending, axial rotation, and extension.
