ALTERATION OF PELVIC PARAMETERS IN ADJACENT SEGMENT DEGENERATION

ABSTRACT Objective: To describe the changes in the spino-pelvic parameters obtained after lumbar spine surgery. Methods: Prospective study. Results: The post-surgical pelvic parameters were found as follows: pelvic incidence of 75.75°, sacral slope 46.18°, pelvic tilt 19.68°. The sagittal balance was 30.93 mm, the postoperative lordosis was 66.06°. The surgery has significant effects on the patient's pain and posture. In our analysis, in a 12-month follow-up, we found: four patients (8.8%, two males and two females) with degeneration of the adjacent segment according to the criteria, and there was no degeneration of the underlying segment, nor any relationship with the spino-pelvic parameters. Conclusions: The degeneration of the adjacent segment does not correlate with the pelvic parameters. Level of Evidence II, Prognostic studies. Investigation of the effect of characteristics of a patient on the outcome of the disease.
