In our series, the corrections of the segmental kyphotic angle were similar to those found in the study of Cho et al., who compared patients submitted to three or more SPOs with those submitted to one PSO for sagittal imbalance. They found an angle of correction of segmental kyphosis of 33.0º ±9.2º and in the group subjected to SPO, this angle was 31.7º ±9.0º.
En nuestra serie, las correcciones del ángulo cifótico segmentario son parecidas a las del trabajo de Cho et al. en el que se comparaban pacientes sometidos a tres o más SPO y los sometidos a uma PSO por desequilibrio sagital fijo hallando una corrección del ángulo de cifosis segmentaria de 33,0º±9.2º y el grupo sometido a SPO de 31,7º±9.0º.
