Comparative Study On Autogenous Iliac Bone And Titanium Mesh In Anterior Cervical Fusion

Objective: Comparison of autogenous iliac bone and titanium mesh inanterior cervical fusion surgery. Methods: Retrospectively reviewed Spinedevision of the First Hospital of Jilin University since January2008toSeptember2011using the self-implementation of the reconstruction of59casesof iliac bone and titanium mesh in anterior cervical.Comparative analysis ofintraoperativethe amount of bleeding, postoperative complications, imagingdata、the stability of cervical spine and the situation of nerve function toimprove by using the two methods. Results: Group B has a significant loweroperative time and blood loss were (P<0.01) with125.2±10.8min,105.2±13.2mlcompared with Group B with103.1±6.4min,82.3persons7.5m; Group A hashigher postoperative complication than group B (P>0.05) with rate of32.1%.There is2patient with iliac infections,3patient with numbness in the front ofthe thigh,2patients with titanium mesh shift in group B; Cervical lordosisimproved significantly compared with the preoperative (P<0.05); Cervicallordosis of group B reducts less than group A in3months compared with theimmediate postoperative and1year postoperative compared with3months.Dof group A are:1.86±1.97mm,-0.04±0.15mm; t D of group B are:1.96±1.39mm,-0.06±0.19mm, the difference between the two groups wasstatistically significant (P<0.01); Group B had lower height loss in posterior margin both from postoperative to3months and from3months to1year. Therewere significantly different between the two groups (P<0.01),the data were:-0.19±0.29mm,-0.06±0.31mm in group A,-1.57±0.53mm,-0.07±0.24mm ingroup B; One case with vertebral collapse in group A and two cases withtitanium mesh shift in group B, and they were all in the three months afteroperation, all cases achieve fusion in6months; the fusion rate of group A was96.4%in three months, group B was93.5%, the difference was not statisticallysignificant (P>0.05); two group all have postoperative neck axial symptomsafter surgery,the number of march axial symptoms in group A is larger thangroup A, but there was no significant difference (P>0.05); There are nosignificant differences in the two groups of neurological improvement rate.Conclusion: Titanium mesh is better than iliac on maintain cervicallordosis and height of fusion segments after surgery;Neck axial symptoms areassociated with height and cervical lordosis of cervical fusion segment, can bereduced with maintaining the height and curvature of cervical fusion segment;There is higher incidence of implants displacement in C6than C4, C5segmentafter of fusion vertebrae subtotal reconstruction.
