Abstract

Abstract: Objective To study dynamic cervical implant (DCI) in the treatment of single level operation curative effect of cervical spondylosis. Methods We reviewed 16 cervical spondylosis patients treated with DCI. Surgical levels include C4-5, C5-6, C6-7, among them 3 cases at C4-5, 7 cases at C5-6, 6 cases at C6-7. All patients had complete follow-up data, including preoperative, postoperative 3 months, postoperative 6 months and postoperative 12 months. Comparison of preoperative and postoperative clinical score by visual analogue score (VAS) and neck disability index (NDI) were done. The operation time, amount of blood loss, cervical extension and flexion prosthetic stability, displacement of the prosthesis, subsidence, and adjacent segment motion imaging were recorded. Results Compared with preoperative NDI and VAS score, significance were found at 3 months, 6 months and 12 months follow-up, VAS and NDI scores significantly improved. Good mobility was maintained and no adjacent segment degeneration was observed. No internal fixation loosening, displacement, no perioperative nerve injury and infection cases occurred. Conclusion 1 year follow-up results showed that single level cervical spondylosis decompression and internal dynamic fixation with DCI has excellent surgical outcomes for cervical spondylosis, maintaining index and adjacent segmental mobility, and improve the cervical sagittal alignment.
