Correlation between the ease of cage plates implantation and endplate Hounsfield unit value during ACDF: a retrospective study

To investigate the correlation between the implantation status of the ROI-C cervical cage plates and the Hounsfield unit(HU) value of the target vertebral endplate during anterior cervical decompression and fusion (ACDF)surgery. Review of patient data undergoing ACDF from January 2018 to December 2021. Data on gender, age, body mass index, history of hypertension, diabetes, hyperlipidemia, smoking, alcohol consumption, cervical cage plates status, and HU values of the cervical vertebral endplate. Logistic regression analysis was used to evaluate the relationship between the HU values and the plates status. A total of 17 cases (12.1%) had misplaced implants during surgery. There were statistical differences in gender, long-term smoking history, drinking history, and cervical vertebral endplate HU values between the abnormal implantation group and the normal implantation group (P
