The Quest of Sagittal Balance Parameters and Clinical Outcome after Short Segment Spinal Fusion
Rami Alqroom.
Abstract
Introduction: Sagittal imbalance leads to muscular distress and results in low back pain. Objectives: This study scrutinize the segmental impact of short spinal fusion on spinopelvic parameters and the global patients clinical outcome. Materials and Methods: A retrospective analysis evaluated 56-patients who underwent lumbar fusion surgery at Klinikum Dortmund, from July 2013 to February 2014. The population was allocated into two groups: (1-level group), (2-levels group). EOS imaging applied for radiological evaluation and measurements of the following spinopelvic parameters: pelvic incidence (PI), sacral slope (SS), pelvic tilt (SS), lumbar lordosis (LL), and sagittal vertical axis (SVA). The radiological measurements were implemented during the preoperative, postoperative, 3 months and 1 year follow-up visits. All patients completed clinical questionnaires. Results: Statistically, the Pearson correlation coefficient revealed in the 1-level group that the clinical parameters correlated with the PT (R=0.40), SSA (R=-0.38) and SVA (R=-0.41) (p
