Abstract: 【Abstract】〓Objective〓To compare the clinical efficacy of anterior cervical discectomy with plate fixation (ACD) and Zero-profile implantation (zero-P). Methods〓A total of 134 cases were included in the study from December 2009 to February 2013. The patients (ACDF group, n=71) were performed anterior discectomy and interbody fusion with plate internal fixation and those (Zero-P group, n=63) underwent anterior discectomy and Zero-Profile implantation..All patients had different degrees of pain on the neck and shoulder, pain on the.limbs and numbness and weakness,.of which 68 cases with trunk banding and double lower limbs on cotton,.12 cases with mild defecation dysfunction..Single segment operation time,.intraoperative bleeding,.pre- and post-operation imaging,.VAS,.JOA,.D value and SWAL-QOL score in two groups were assessed and compared. Results〓All the cases were followed up for 8-24 months with an average 13±2.5 months..In ACDF and Zero-p group,.the operation time of each segment of ACDF and Zero-p group was 65±11.3 min and 47±7.6 min respectively,.estimated bleeding loss was 68.5±21.1 ml and 42.7±14.4 ml, hospital stay was 5.4 and 4.2 days..Zero-p group showed a better clinical efficacy when compared with ACD group, and there were significant differences. No implant subsidence or collapse, implant loosening screw were found. Conclusion〓The model of zero notch implant system has the advantages of simple operation, short operation time, less bleeding and good early clinical effect. The Zero-P implant is a valid alternative to anterior cervical plating after ACDF with a very low incidence of postoperative dysphagia and no implant-related complications.
