• W4254993606 abstract "Introduction Adults with spinal deformity typically present with pain and disability. Aim Our objective was to compare outcomes for operative (op) and nonoperative (nonop) treatment for ASD based on a prospective, multicenter patient population. Material and Methods This is a multicenter, prospective analysis of consecutive ASD patients electing for op or nonop care at enrollment. Inclusion criteria: age > 18 year and ASD. Propensity scores were used to match op and nonop patients based on baseline (BL) ODI, SRS22, maximum thoracolumbar/lumbar Cobb angle, pelvic incidence to lumbar lordosis mismatch (PI-LL), and leg pain numeric rating scale (NRS) score. Results A total of 689 patients met with the criteria, including 286 op and 403 nonop, with mean ages of 53 and 55 years, minimum 2-year follow-up rates of 86 and 55%, and mean follow-up of 24.7 and 24.8 months, respectively. At BL, compared with nonop, op patients had significantly worse HRQL based on ODI, SRS22, SF36, and leg and back pain NRS ( p < 0.001) and had worse deformity based on pelvic tilt, PI-LL, and C7SVA ( p ≤ 0.002). Before reaching minimum 2-year follow-up 38 nonop patients converted to op treatment and were analyzed in the op group. At minimum 2-year follow-up all HRQL measures assessed significantly improved for op patients ( p < 0.001), but none of these measures improved significantly for nonop patients ( p ≥ 0.11). Total 97 matched op–nonop pairs were identified based on propensity scores. At last follow-up the 97 matched op patients had significant improvement in all HRQL measures assessed ( p < 0.001), but the 97 matched nonop patients lacked significant improvement in any of the HRQL measures ( p ≥ 0.20). Paired op–nonop analysis demonstrated the op patients to have significantly better HRQL scores at follow-up for all measures assessed ( p < 0.001), except SF36 MCS ( p = 0.058). Overall minor and major complication rates for op patients were 53 and 40%, respectively. Conclusion Op treatment for ASD can provide significant improvement of HRQL measures at minimum 2-year follow-up. In contrast, nonop treatment appears to at best maintain presenting levels of pain and disability." @default.
