AB  - STUDY DESIGN: Retrospective case series. OBJECTIVE: To evaluate if spine
      measurement software can simulate sagittal alignment following pedicle
      subtraction osteotomy (PSO). METHODS: We retrospectively reviewed consecutive
      adult spinal deformity patients who underwent lumbar PSO. Sagittal measurements
      were performed on preoperative lateral, standing radiographs. Sagittal
      measurements after simulated PSO were compared to actual postoperative
      measurements. A regression equation was developed using cases 1-7 to determine
      the amount of manual rotation required of each film to match the simulated
      sagittal vertical axis (SVA) to the actual postoperative SVA. The equation was
      then applied to cases 8-13. RESULTS: For all 13 cases, the spine software
      accurately simulated lumbar lordosis, pelvic incidence lumbar lordosis mismatch, 
      and T1 pelvic angle, with no significant differences between actual and simulated
      measurements. The pelvic tilt (PT), sacral slope (SS), thoracolumbar alignment
      (TL), thoracic kyphosis (TK), T9 spino-pelvic inclination (T9SPi), T1
      spino-pelvic inclination (T1SPi), and SVA were inaccurately simulated. The PT,
      SS, T9SPi, T1SPi, and SVA all change with manual rotation of the film, and by
      using the regression equation developed with cases 1-7, we were able to improve
      the accuracy and decrease the variability of the simulated PT, SS, T9SPi, T1SPi, 
      and SVA for cases 8-13. CONCLUSIONS: Dedicated spine measurement software can
      accurately simulate certain sagittal measurements, such as LL, PI-LL, and TPA,
      following PSO. A number of measurements, including PT, SS, TL, TK, T9SPi, T1SPi, 
      and SVA were inaccurately simulated. Our preliminary algorithm improved the
      accuracy and decreased the variability of certain measurements, but requires
      future prospective studies for further validation.
