CORRELATION BETWEEN DEGENERATIVE DISEASES OF THE LUMBAR SPINE AND TYPES OF LUMBAR LORDOSIS

ABSTRACT Objective: Evaluate the relationship between the incidence of different types of degenerative diseases of the spine and lumbopelvic biomechanics, according to the types of lordosis of Roussouly's classification. Methods: Retrospective study of medical records and results of imaging exams of patients seen at a private hospital in São Paulo. The sagittal alignment of these patients was evaluated by classifying them according to Roussouly into 4 types, based on panoramic radiographs of the spine. These results were correlated with the patient's degenerative diagnosis (Herniated disc, Canal stenosis, Spondylolisthesis, degenerative discopathy and Facet arthrosis). Statistical tests were performed comparing the types of curvature and diagnoses identified. Results: 418 patients were evaluated, 51.4% male and 49.6% female. The vast majority of patients, about 54%, had a diagnosis of herniated lumbar disc. There was a statistically significant difference that showed a predilection for surgical treatment in cases classified as Type I and Type II in the Roussouly classification. There was no statistically significant difference that correlated the types of lumbar lordosis with the diagnosis presented by the patients. Conclusion: There is no statistically significant difference that correlates the type of lumbar lordosis according to Roussouly with lumbar degenerative diseases. In contrast, patients classified as Type 1 and Type 2 by Roussouly underwent a greater number of surgical treatments compared to patients type 3 and 4, with statistical relevance. Level of evidence 2; Retrospective prognostic study.
