  • In the medical literature, multiple methods of radiological measurement of lordosis have been described. The Cobb method (L5-S1) is not considered the most accurate..


  • The correction of the loss of lordosis is considered one of the essential factors in the post-surgical result. Currently multiple centers use computer-assisted procedures in the evaluation of the regional or global curvature of the column Measurement of post-surgical lordosis is not performed under the same conditions as pre-surgical planning, so the result is not comparable.


  • Post-surgical radiology does not allow a linear estimation of the real value of the lordosis. 


  • CT and MR overestimate the value of lordosis in patients with hipolordosis and underestimate it in patients with hyperlordosis. 


  • Standardized studies should be carried out, under similar conditions, with a high number of patients and with the same measurement system so that the results can be assessed.
