Objective To investigate the relationship between the K-line tilt and classical cervical parameters such as the C2–C7 sagittal vertical axis (SVA), cervical lordosis, and the T1 slope in cervical sagittal alignment. We assessed whether the K-line tilt can be used as an excellent cervical parameter. Methods We reviewed 50 patients aged 60–89 years who visited the spine center outpatient clinic from May 2017 to Sep- tember 2017 through cervical spine lateral radiography and checked the cervical spine parameters. All targeted patients were randomized without any prejudice. Radiographic measurements included the K-line tilt, C2–C7 lordosis, the C2–C7 SVA, the T1 slope, and T1 slope minus C2–C7 lordosis (T1S-CL). Pearson correlation coefficients were calculated between the K-line tilt and each cervical parameter. Results Of the 50 patients, 33 were men. The mean age of the patients was 70.84 ± 7.52 years. The mean K-line tilt was 11.28 ± 8.31°. The K-line tilt was correlated with the C2–C7 SVA (r = 0.813, P = 0.000) and T1S-CL (r = 0.315, P = 0.026). Conclusion This study showed that the K-line tilt is also a useful parameter like the C2–C7 SVA and T1S-CL in cervical sagittal alignment. Graphical Abstract These slides can be retrieved under
