Measuring Outcomes in Spinal Deformity Surgery

The SRS-22 and ODI are the predominantly used PRO measurements for deformity surgery. Correction of sagittal alignment correlates with improved PRO, and T1-SPI outperforms the SVA. Functional outcomes and accelerometer measurements represent newer methods of measuring outcomes that have not yet been widely adopted or validated. Further adoption of a minimum set of core outcome domains, PROs such as SRS-22, and contributing risk factors will help facilitate international comparisons and benchmarking, and ultimately enhance value-based healthcare.
