HOW SPINOPELVIC PARAMETERS ARE AFFECTED AFTER SURGICAL TREATMENT FOR SCHEUERMANN’S KYPHOSIS

Özet

Objective: The relationship between the pelvis and spine is critical in global spinal alignment and sagittal imbalance and its associated compensatory mechanisms have been reported to correlate with negatively influenced quality of life. There are several studies evaluating the sagittal spinopelvic parameters (SSPs) in many areas of spinal disorders but studies evaluating the SSPs in Scheuermann’s kyphosis (SK) are limited. To evaluate the effect of surgical treatment on SSPs in patients affected by SK. Materials and Methods: The database of the institution was retrospectively reviewed to identify patients who underwent surgery for SK between the years of 2012 and 2015. Twenty-nine patients were included, and records of these patients were reviewed. Changes in pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), cervical lordosis (CL), thoracic kyphosis (TK), lumbar lordosis (LL), and the sagittal vertical axis (SVA) measurements were compared. Results: There were no significant changes in PI, PT, SVA, and SS compared to preoperative values. There were decreases in TK and LL measurements, which were statistically significant. Conclusion: Surgical treatment for SK seems to have little or no influence on changing SSPs.
