ABSTRACT
Objective To compare the postoperative imaging anatomical parameters and the related perioperative parameters of continuous double-gap cervical spondylotic myelopathy patients who underwent anterior cervical disectomy and fusion (ACDF)or anterior cervical corpectomy and fusion (ACCF)and ACDF so as to learn about the clinical effects of the two methods.Methods We included 5 1 patients in ACDF group (male∶female ratio=32∶19;mean age 56.3±29.4 years),and 47 patients (male∶female ratio=35∶12;mean age 49.1±22.8 years)in ACCF group.We measured the sex ratio,mean age,average length of hospital stay,mean operative time, and average intraoperative blood loss in ACDF group and ACCF group.The patients were followed up at six months,1 year,and 2 years after operation.The JOA score and imaging parameters were recorded for statistical analysis by SPSS 19.0.Results Patients in ACDF group had shorter operative time,less operative bleeding and shorter hospitalization duration than those in ACCF group.There was no significant difference in postoperative JOA score between ACDF and ACCF group.Patients in ACDF group had better imaging indexes than those in ACCF group.Conclusion ACDF has better screening efficacy than ACCF in treatment of continuous double-gap cervical disc herniation of cervical spondylotic myelopathy.
