Spinal pelvic parameters before and after the Spine fixation and its impact on clinical outcomes: A study from a tertiary care hospital

Degenerative spine disease (DSD) is a progressive disease of the spine affecting inter vertebral discs, bones, soft tissues and joints. This condition not only affects the stability of the spine but it also affects its alignment. Alignment of the spine is of special importance at Spinal-pelvic junction specially its sagittal alignment, broadly referred to as Spinal sagittal balance. Main objective parameters that determine the Spinal sagittal balance is Sacral slope (SS), Pelvic tilt (PT), Lumbar lordosis (LL) and Pelvic incidence (PI).

Lumbar spine fixation is a surgical procedure aimed to restore not only the stability but also the alignment of the spine. In this retrospective study spanning over 2 years at a tertiary care hospital, we evaluated patients before and after the spine fixation surgeries in terms of their Spinal sagittal parameters. Total 52 patients were included in the study and followed for one year period, with majority (32) patients showing correction of the parameters especially Sacral slope, Lumbar lordosis and Pelvic tilt. Patients with corrected spinal alignment also showed significant clinical improvement in terms of low back pain and Oswestry disability index (ODI).

Based on the results of the study, we can conclude that Spine fixation improves Sagittal balance of the spine in selected population.
