Abstract Objective To evaluate the clinical outcomes and complications of ACDF with Zero-P and cages with plate in treating multiple-level cervical spondylosis (MCS) with cervical kyphosis.Methods Clinical data of patients with MCS caused by degenerative disc herniation were retrospectively analyzedfrom August 2012 to March 2016.Clinical parameters including Japanese orthopedic association (JOA)score,neck disabled index(NDI) and visual analogue scale(VAS) were evaluated.The orthopaedic effect of Zero-P and cages with plate were investigated according to changes of the cervical Cobb angle and intervertebral space height.Results All patients were followed up for an average of 24.7 months in Group A and 25.2 months in Group B.45 cases of patients’ main symptoms were significantly reduced.There was no serious complications.Postoperative symptoms improved with time.The JOA score,the VAS score,the NDI index,the cervical intervertebral height and the Cobb angle one month after operation and during last follow-up were improved significantly compared with the preoperative data.The differences were statistically significant(P<0.05) in Group A and Group B.But the differences between Group A and Group B were not statistically significant(P>0.05).Conclusion Based on the follow-up,Anterior cervical decompression and fusion with Zero-P and cages with plate could achieve good effect in treating multilevel cervical spondylotic myelopathy with kyphosis.
