Comparison of Mid-Long Term Results of Cervical Cage and Cervical Disc Prosthesis in Patients with Single Level Cervical Disc Herniation

Aim: Continuous advancements in technology have facilitated the maintenance of spinal biomechanical properties, emphasizing the preservation of functional spinal segments. Therefore, this study focuses on comparing the mid- to long-term outcomes of cervical cage and cervical disc prosthesis (CDP) in patients with single-level cervical disc herniation. Material and Method: This study included 51 patients diagnosed with cervical disc herniation. Among these, 25 underwent CDP, while 26 received a cervical cage. The mean follow-up period was 7.3 years. All surgeries were performed between 2021 and 2022 at a hospital in Türkiye. It was ensured that none of the patients had a prior history of spinal surgery. The demographics of the two groups were comparable. Radiographic evaluations and clinical outcomes were assessed, focusing on degenerative changes, cervical spine motion, and radicular pain in both groups. Results: The mean age in the CDP group was 46 years, compared to 43 years in the cervical cage group. Recurrent cervical pain was observed in only one patient in the CDP group, whereas it was reported in eight patients in the cervical cage group over the 7.3-year follow-up period. Conclusion: In conclusion, CDP was found to be a more effective treatment compared to cervical cage in patients with cervical disc herniation.
