Abstract:
Objective To investigate the prognostic value of vertebral CT parameters for early fusion sink after transforaminal lumbar interbody fusion(TLIF).Methods The clinical and imaging data of 178 patients with lumbar degenerative diseases treated by TLIF were retrospectively studied.The patients were divided into the sedimentation group(n=57)and the non-sedimentation(n=57)group according to the patient's fusion device settlement 3 months after surgery.The results of general data and CT image parameters were compared between the two groups.Multivariate Logistic regression was used to analyze risk factors of early fusion subsidence,and the prediction efficiency was analyzed.Results The incidence of the early fusion sink was 32.0%.Compared with the non-sedimentation group,the sedimentation group had a higher proportion of patients aged≥60 years,osteoporosis,L5-S1 and intervertebral space height,larger fusion contact area and segmental lordosis angle and lower lumbar CT value(P＜0.05).Logistic regression analysis showed that age≥60 years old,surgical level L5-S1,high intervertebral height and large segmental lordosis angle were independent risk factors for the early fusion after TLIF,while high lumbar CT value was protective factor(P＜0.05).Subject working characteristic curves showed that the area under the curve(AUC)of lumbar CT value,intervertebral height,segmental lordosis angle combined with AUC were higher than those of patients aged≥60 years,surgical segment L5-S1,lumbar CT value,intervertebral height,segmental lordosis angle applied alone(P＜0.05).Conclusion Vertebral CT parameters of lumbar CT value,intervertebral height and segmental lordosis angle have higher predictive value for the early fusion after TLIF,and the combined prediction value of the three parameters is higher.
