Aims and objectives
Sagittal malalignment often wrongly coined sagittal imbalance refers to the loss of normal alignment in the sagittal plane and is associated with recruitment of compensatory mechanism.
Sagittal malalignment by itself is not an indication for surgery but it must be seen as a factor of great relevance when evaluating any patient referred for problems at the vertebral level.
Although there is no consensus on whether it is necessary to perform radiological tests in the postoperative period of asymptomatic patients undergoing spinal fusion arthrodesis,
Methods and materials
A retrospective study of patients operated in our Hospital Center between 2012 and 2017 was carried out.
The impossibility of performing an adequate measurement of the lumbar lordosis in any of the radiological techniques used in the study was established as an absolute exclusion criterion,
regardless of the cause that generated it.
The criteria for inclusion in the study were:
To be operated on an instrumented arthrodesis of the lumbar spine regardless of the number of levels and the cause of the intervention
It was necessary to review the imagen tests of more than 509 patients in order to be able to recruit the 240 study patients.
This can be explained by two reasons; the lower quality of the radiography in the immediate postoperative period and also the complexity of the treated pathology.
Unlike the article by Jae Young Hong,
in our study the number of patients with severe scoliosis was low due to the inability to clearly establish the points of measurement of the angle of Cobb....
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 columnMeasurement 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...
