Abstract
BACKGROUND: To explore the predictive parameters for adjacent segment disease (ASD) after anterior cervical arthrodesis at the sagittal measurement of thoracic inlet.
METHODS: We included 212 subjects treated with anterior cervical fusion surgery to identify predictive parameters for ASD . We applied the multivariate logistic regression to find the revelant parameters.
RESULTS: A total of 200 patients complete the final follow-up. The results of logistic regression analysis showed that preoperative T1 slope of less than 19.50 could be a predictive parameters of ASD after the anterior cervical arthrodesis(P<0.05).
CONCLUSION: Keeping preoperative sagittal imbalance of thoracic inlet is vital to the. cervical degenerative disease, while T1 slope of less than 19.50 appears as an independent risk factor for the ASD, keep the T1 slope more than 19.5 is reasonable.
