Abstract: Objective To compare the clinical efficacy of a new low notch plate system (Carmen synchronous adaptive cervical fusion system) and Zero-p in the treatment of single level cervical spondylotic radiculopathy (CSR). Methods Retrospective analysis was made on 48 patients with single level cervical spondylosis of nerve root type admitted from January 2015 to January 2020,including 26 patients with new low notch steel plate system (observation group) and 22 patients with Zero-P (control group).The operation duration,intraoperative blood loss,incidence of postoperative dysphagia,preoperative and postoperative JOA scores,cervical dysfunction index (NDI) Visual analog score of pain (VAS) and Cobb angle and intervertebral space height of postoperative imaging.Results There was no significant difference between the two groups in terms of operation time,intraoperative blood loss and the incidence of postoperative dysphagia (P>0.05).All patients were followed up for 12-15 months,with an average of (12.6±0.7) months.There was no significant difference in JOA score,NDI index and VAS score of pain between the two groups before and 3 and 12 months after operation (P>0.05). Conclusion The clinical efficacy of the new low notch plate system in the treatment of single segment cervical spondylotic radiculopathy is equivalent to Zero-P,and it is a reliable new type of anterior cervical internal fixation system.
