Comparison of two fixation fusion systems in anterior cervical discectomy and fusion surgery

Objective The study aimed to investigate and compare the efficiency and safety of two fixation fusion systems in anterior cervical discectomy and fusion(ACDF)surgery.Methods Retrospective analysis of Clinical data of 58 patients undergoing ACDF surgery admitted to Beijing Friendship Hospital,Capital Medical University,from March 2017 to March 2019 were retrospectively analyzed.Titanium steel plate combined with cage fusion device(plate group,PG 31 cases,35 fusion segments)and Zero-P fixation fusion device(Zero-P group,ZP 27 cases,33 fusion segments)was applicated in different operations.The operation time,blood loss,main complications,postoperative pain(VAS)score,neurological function(JOA)score,radiological data were observed and compared statistically.Results Fifty eight patients were followed up for more than 12 months.The operation time of ZP group was(99.4±20.6)min,which was shorter than that of PG group[(111.9±19.7)min],the difference was statistically significant(P<0.05).The blood loss of(35.9±14.2)mL in the ZP group was significantly less than that in the PG group[(51.0±26.6)mL],and the difference was statistically significant(P<0.05).There was no significant difference in the incidence of dysphagia symptoms in the two groups within 2 weeks after surgery(3.7%vs.12.9%)(P>0.05).The incidence of foreign body sensation in the esophagus within 2 weeks after operation in the ZP group was significantly lower than that in the PG group(7.4%vs.29.0%),and the difference was statistically significant(P<0.05).There was no statistically significant difference in the incidence of implant loosening(0 vs.3.2%)and interbody non-union within 6 months after operation(3.7%vs.6.5%)in the two groups(P>0.05).VAS score[(1.7±1.1)points vs.(1.6±1.1)points],JOA score[(15.7±0.9)points vs.(15.4±1.1)points],nerve function Recovery rate[(83.4±12.9)%vs.(79.4±15.2)%],Cobb angle of physiological curvature[(14.6±3.8)°vs.(13.7±3.4)°]and height of the posterior edge of the surgical intervertebral space[(8.0±1.5)mm vs.(7.5±1.7)mm]at 12 month follow-up in the two groups,the differences were not statistically significant(P>0.05).Conclusion During the ACDF operations,it was efficiency and safety with titanium steel plate combined with cage and Zero-P fixation fusion systems.The application of Zero-P device can make the operations more quicker,it could significantly reduce blood loss and the incidence of esophagus foreign body sensation within 2 weeks after the operation.The Zero-P device was worthy of clinical promotion.
