| Popis: | Study design This is nonconcurrent prospective study approved by the Institutional Research Ethics Committee. Objective The purpose of this study is to determine if the cranial sagittal vertical axis (Cr-SVA) measured in full spine standing radiographs is a better predictor of clinical results than the C7 sagittal vertical axis (C7-SVA) in adult patients operated on spinal deformity with a minimum 2-year follow-up after surgery. Summary of background data The Cr-SVA has recently been described as a better predictor of health-related quality of life outcomes than the C7-SVA for patients with adult spinal deformity (ASD) before undergoing surgery. This has not been confirmed in patients after ASD surgery. Methods Inclusion criteria were age at surgery more than 25 years and a minimum 2-year follow-up after a ≥5 level fusion for ASD. Full-length standing lateral radiographs (including nasion-inion line, spine, and femoral heads) and Scoliosis Research Society 22 Questionnaire and SF36 questionnaires were available for every patient at the final follow-up. The distance from the Cr-SVA to the posterior corner of S1 (Cr-SVA-S) and to the centers of the hip (Cr-SVA-H) was measured and also the C7-SVA, lumbar lordosis, pelvic incidence, pelvic tilt, and PI-LL. Results Sixty-five patients (58 female individuals) operated on ASD in a single institution were included. Age at surgery was 61 years (26-67). The mean follow-up was 53 months (24-120). Spearman rank-order test showed several significant correlations. After multivariable analysis, only Cr-SVA-S and age persisted as predictors for Scoliosis Research Society (SRS) image scores, Cr-SVA-H for SRS satisfaction, Cr-SVA-H and age for SRS total scores, Cr-SVA-H and age for SF36 Physical Function, Cr-SVA-S for SF36 Role Physical, Cr-SVA-H for SF36 Bodily Pain, and Cr-SVA-H for SF36 Role Emotional. Conclusions The Cr-SVA measured in full spine standing radiographs seems to be a better predictor of health-related quality of life outcomes than the C7-SVA for adults operated on spinal deformity >2 years after surgery. |
