Abstract Background The self-locking cage (ROI-C, LDR, Troyes, France) has been clinically applied in the treatment of cervical degenerative disc disease (CDDD). However, only a few long-term clinical and radiographic studies have been conducted on the treatment of spinal cord injury without fracture or dislocation (SCIWFD) so far. A comparison between ACDF with either ROI-C or CCP was performed to determine the better treatment for SCIWFD. Methods A total of 83 patients who underwent ACDF using either ROI-C or CCP were reviewed for radiological and clinical outcomes. The cohort comprised 60 males and 23 females, aged between 32 and 88 years old, with an average age of 58.23 years. All patients exhibited symptoms of nerve injury, including limb numbness, muscle weakness, hypoesthesia or urinary dysfunction. The preoperative ASIA classification of spinal nerve function: 7 cases of grade A, 23 cases of grade B, 34 cases of grade C and 19 cases of grade D were included in the study. Results A total of 48 patients underwent ACDF with ROI-C, while 35 patients received a conventional cage-plate. They were studied with a follow-up of 28.63 ± 17.41 months and 29.48 ± 15.43 months respectively. No significant difference was found in blood loss, JOA and ASIA between the two groups. No significant difference was found in cervical lordosis (CL) (P > 0.05). However, statistical difference was found in disc height of fused segment and T1 slope between the two groups (P 0.05). There was significant difference in the incidence of dysphagia. Both of two groups achieved bony fusion at final follow-up. Conclusion Our study demonstrated that ROI-C has the same efficacy as CCP in improving the cervical stability in treatment of SCIWFD. The migration of cage didn’t occur in ROI-C group at final follow-up, showing steadily fixed in cervical column. Moreover, the ROI-C does have the advantages of good therapeutic effect, mis-invasive, shorter operation time and fewer complications.
