TLDR
This study shows that although even mildly positive sagittal balance is somewhat detrimental, severity of symptoms increases in a linear fashion with progressive sagittal imbalance, and shows that kyphosis is more favorable in the upper thoracic region but very poorly tolerated in the lumbar spine.Abstract:
Study Design.This study is a retrospective review of 752 patients with adult spinal deformity enrolled in a multicenter prospective database in 2002 and 2003. Patients with positive sagittal balance (N = 352) were further evaluated regarding radiographic parameters and health status measures, includread more

Pelvic tilt and truncal inclination: two key radiographic parameters in the setting of adults with spinal deformity.
TL;DR: This study confirms that pelvic position measured via PT correlates withHRQOL in the setting of adult deformity and demonstrates significant T1–SPI correlation with HRQOL measures and outperforms SVA.

TL;DR: Data from this study show that there is excellent inter- and intra- rater reliability and inter-rater agreement for curve type and each modifier and the high degree of reliability demonstrates that applying the classification system is easy and consistent.

Adult spinal deformity-postoperative standing imbalance: how much can you tolerate? An overview of key parameters in assessing alignment and planning corrective surgery.
TL;DR: Good clinical outcome requires achieving proper spinopelvic alignment in the treatment of adult spinal deformity, and restoring low sagittal vertical axis and pelvic tilt values are critical goals, and should be combined with proportional lumbar lordosis to pelvic incidence.

TL;DR: In this article, the authors evaluated correlations between spinopelvic parameters and health-related quality of life (HRQOL) scores in patients with spinal deformity and found that spinopels can provide a more complete assessment of the sagittal plane.
Journal ArticleDOI
The adult scoliosis
TL;DR: Overall, a satisfactory outcome can be expected in well-differentiated indications and properly tailored surgical procedures, although until today prospective, controlled studies with outcome measures and pre- and post-operative patient’s health status are lacking.

Correlation of radiographic parameters and clinical symptoms in adult scoliosis
TL;DR: This study suggests that restoration of a more normal sagittal balance is the critical goal for any reconstructive spine surgery and suggests that magnitude of coronal deformity and extent of Coronal correction are less critical parameters.

An analysis of sagittal spinal alignment in 100 asymptomatic middle and older aged volunteers
TL;DR: The majority of asymptomatic individuals are able to maintain their sagittal alignment despite advancing age, and increasing age correlated to a more forward sagittal vertical axis with loss of distal lumbar lordosis but without an increase in thoracic or thoracolumbar kyphosis.

TL;DR: This study showed that lateral vertebral olisthy, L3 and L4 endplate obliquity angles, lumbar lordosis, and thoracolumbar kyphosis were significantly correlated with pain.

TL;DR: Satisfaction with the results of treatment may be reduced in patients with four or more major co-existent medical problems, insufficient sagittal correction, and resultant pseudarthrosis.

TL;DR: The clavicle position for obtaining lateral 36” radiographs produces significantly better overall visualization of critical vertebral landmarks and may result in more accurate radiographic measures and may minimize repeated radiograph exposures.
