Evaluation of CT Imaging in Patients with Lumbar Degenerative Diseases after Internal Fixation Combined with Interbody Fusion

Objective To analyze the effect of CT imaging on lumbar degenerative diseases after internal fixation combined with interbody fusion.Methods From June 2016 to July 2018,50 patients with lumbar degenerative changes were treated with interbody fusion and internal fixation.Anteroposterior and lateral lumbar CT examination were recorded before the operation and 1 month,6 months and 1 year after the operation.The height of intervertebral space,effective upper endplate area and fusion rate of the lumbar spine were observed du ring the follow-up period.Results The intervertebral space height was significantly improved at different times after operation(P<0.05).The intervertebral space height of patients with 5 mL and 6 mL bone graft volume at 6 months and 1 year after operation was significantly higher than that in patients with 4 mL bone graft volume(P<0.05);the volume of intervertebral bone graft volume was found after 6 months and 1 year of follow-up The fusion rate of 5 mL and 6 mL patients was significantly higher than that of 4 mL intervertebral bone graft volume(P<0.05).Conclusion Internal fixation combined with interbody fusion is an effective surgical scheme for treating of lumbar degenerative diseases.Autogenous bone graft fusion with 5 mL or more bone graft volume can significantly improve the success rate of postoperative intervertebral fusion.CT imaging examination has reliable value in evaluating the therapeutic effect of internal fixation combined with interbodyfusion.
