Correlation of height change of intervertebral space of fused segment with axial synptoms after anterior cervical fusion / 中国矫形外科杂志

ABSTRACT

[Objective] To investigate the height change of intervertebral space after anterior cervical fusion and its relation to neck axial symptoms.[Method]Totally 122 patients receiving anterior cervical fusion were followed up for 2 to 5 years,average 3.9 years.The height change of intervertebral space of the fused segment on X-rays were evaluated before,3 months and 2 years after operation.All patients were classified into 3 groups by means of the postoperative height change of intervertebral space.The axial symptoms after operation were observed and analyzed during follow-up.[Result]The incidence of neck axial symptoms was 54.55%,25.84% and 45.45%,respectively.There were significant differences in statistical analysis in group A group B,group B to group C(x2=7.18,P0.0125).[Conclusion]There is significant relation between height change of intervertebral space and neck axial symptoms after anterior cervical fusion.
