Abstract
Authors aim to evaluate the correct placement of TDR using the instant center of rotation (ICR) as a guide. Placement of disc would be divided into three groups using a standard of 1 mm from the ICR: Posterior to ICR, In line with ICR and Anterior to ICR. 49 patients, mean age was 39.96 ± 1.45 years. 42 intraop fluoroscopy images compared to 41 post op radiographic images demonstrated TDR in line with ICR. Total discs replacements can be placed intraoperatively using proper technique with verification confirmed using the ICR postoperatively. Total disc replacement; instant center of rotation; ideal placement; fluoroscopy; adjacent segment disease; less exposure surgery.
