* Significancia (p) obtenida con la prueba t-Student para muestras independientes. DE = desviación estándar. IF = instrumentación más fusión intersomática. LL = lordosis lumbar. LSI = liberación radicular sin instrumentación transpedicular. PI = incidencia pélvica. PI−LL = incidencia pélvica-lordosis lumbar. PT = inclinación pélvica. SS = inclinación sacra. |
