“…Therefore, the surgeon should plan for a more normal sagittal balance of the spine as an important goal of reconstructive spine surgery. According to a recent study assessing the effect of sagittal spino-pelvic alignment on the clinical symptoms of thoracic, lumbar kyphosis (TLK) in osteoporotic patients, sagittal imbalance (SVA > 5 cm) was more closely related to clinical symptoms than other radiological parameters [30]. The main purpose of surgery for kyphosis is reducing deformity, pain, and neurological symptoms, and preventing the curve from worsening.…”

Sagittal parameters of the spine are closely related to the evaluation and treatment of spine disease. However, there has been little research on variations in preoperative sagittal spinal alignment. This study was conducted to assess the variation in sagittal spinal alignment on serial antero-posterior and latero-lateral projections (EOS imaging) in adult patients before spine surgery. The sagittal parameters of 66 patients were collected from two serial images. Comparison between the first and second sagittal parameters was evaluated using the Wilcoxon signed-rank test. Subgroup analysis was performed based on the time interval between radiographs, patient’s age, and type of surgery. The sagittal vertical axis (SVA) exhibited statistically significant changes (p = 0.023), with the mean SVA increasing statistically (61.7 mm vs. 73.6 mm) and standard deviation increasing (51.5 mm vs. 61.6 mm) in the second image. Subgroup analysis showed significant differences in SVA (p = 0.034) in patients with an interval of >3 months; statistical differences in borderline levels in the SVA (p = 0.049) were observed in patients aged >65 years. Other parameters did not show statistically significant differences, except for SVA. Furthermore, SVA differences were statistically significant with increases in the EOS interval (>3 months) and patient age (>65 years).

“…The C7-sagittal vertical axis(C7-SVA) was the distance between the C7 plumb line and the posterior corner of the sacrum. The sagittal imbalance was defined within 50 mm anteriorly and 20 mm posteriorly while the sagittal imbalanced spine was defined beyond this range 17) .…”

Feasibility study. Objectives: To evaluate the association between L1 slope and thoracolumbar spinal parameters of sagittal balance in cases of osteoporotic vertebral fracture. Summary of Literature Review: Recently, interest has emerged in the sagittal parameters of the thoracolumbar spine in cases of osteoporotic vertebral fracture. Materials and Methods: Eighty-five patients were enrolled in this study, including 36 patients with recent osteoporotic vertebral fractures (group 1) and 49 patients who did not have vertebral fractures (group 2). Radiographic parameters including L1 slope, C7 plumb line (C7 PL), sagittal imbalance (C7 PL >50 mm), lumbar lordosis, thoracic kyphosis, pelvic tilt, S1 slope, local kyphotic angle were evaluated on standing lateral radiographs of the whole spine. We analyzed correlations between L1 slope and these parameters.
