Effect of self-locking zero incisure cervical vertebra fusion in the treatment of cervical spondylosis

Objective:To explore the clinical effects of self-locking zero incisure cervical vertebra fusion in the treatment of cervical spondylosis.Methods:The clinical data of cervical spondylosis patients treated with operation were retrospectively analyzed.The patients treated with self-locking zero incisure cervical vertebra fusion and corpectomy combined with interbody fusion cervical plate fixation were divided into the observation group and control group,respectively(15 cases each group).The clinical effects between two groups were compared.Results:The operation time,intraoperative blood loss and postoperative drainage amount in observation group were significantly lower than those in control group (P<0.01).The differences of VAS scores between two groups before operation and after 3 days of operation were not statistically significant(P>0.05).After 3 and 6 months of operation,the VAS scores in observation group were significantly lower than those in control group(P<0.05 and P<0.01).The difference of the JOA score between two groups before operation was not statistically significant(P>0.05).After 3 days,3 months and 6 months of operation,the JOA scores in observation group were higher than those in control group(P<0.05 to P<0.01).The differences of the cervical curvature and intervertebral height between two groups before and after operation were not statistically significant(P>0.05).Compared with before operation,the cervical curvature and intervertebral height in two groups were significantly improved after operation(P<0.01).After 3 months of operation,the scores of physical function,body role function,body pain,general health,vitality,social function,emotional role function and mental health in observation group were higher that than those in control group(P<0.05 to P<0.01).Conclusions:The self-locking zero incisure cervical vertebra fusion in the treatment of cervical spondylosis has little trauma,the postoperative nerve function and recovery of patients are good,the postoperative cervical curvature,intervertebral height and life quality of patients are significantly improved,which is worthy of clinical application.
