  author={Jean-Christophe A Leveque and Brad Segebarth and Samuel R. Schroerlucke and Nitin V. Khanna and John Pollina and Jim A. Youssef and Antoine Tohmeh and Juan S. Uribe},
Study Design. Multicenter, retrospective, institutional-review-board -approved study at 18 institutions in the United States with 24 treating investigators. Objective. This study was designed to retrospectively assess the prevalence of spinopelvic malalignment in patients who underwent one- or two-level lumbar fusions for degenerative (nondeformity) indications and to assess the incidence of malalignment after fusion surgery as well as the rate of alignment preservation and/or correction in… 
Demographic, Surgical, and Radiographic Risk Factors for Symptomatic Adjacent Segment Disease After Lumbar Fusion: A Systematic Review and Meta-Analysis.
This meta-analysis addressed the limitations of prior reviews and summarized evidence with regard to risk factors for ASD following lumbar fusion and future prospective studies should investigate whether modification of these risk factors can reduce the ASD development.
Pre-Operative Planning in Complex Deformities and Use of Patient-Specific UNiD™ Instrumentation
The use of pre-operative planning software and UNiD patient-specific rods has been shown to improve surgeon’s ability to achieve spinopelvic alignment parameters, specifically SVA and PI-LL, along with other possible benefits.
Automatic analysis of global spinal alignment from simple annotation of vertebral bodies
Two methods for automatic GSA measurement are proposed to mitigate such variability and reduce the burden of manual measurements and are potentially suitable to applications in large datasets—e.g., for outcome assessment in surgical data science.
Versus Standard Pre-Bent Rods Radius of Curvature in Patient-Specific Short Rod Constructs
PSSR demonstrate more acute ROC than industry standard rods, mimicking the normal distribution of lumbar lordosis in PSRs, which could help achieve or maintain sagittal alignment and prevent the sequela of flat back syndrome.


Predisposing Characteristics of Adjacent Segment Disease After Lumbar Fusion
This study is the first to use a combination of medical, radiographic, and postoperative sagittal balance as risk factors for the development of adjacent segment disease after lumbar fusion.
Risk Factors of Adjacent Segment Disease After Transforaminal Inter-Body Fusion for Degenerative Lumbar Disease
The incidence and risk factors of adjacent segment disease (ASD) after transforaminal inter-body fusion (TLIF) for degenerative lumbar disease and patients with preoperative sagittal imbalance have a statistically significant increased risk of ASD.
Spinopelvic sagittal imbalance as a risk factor for adjacent-segment disease after single-segment posterior lumbar interbody fusion.
Preoperative global sagittal imbalance (SVA > 50 mm and higher PT), pre- and postoperative lower LL, and PI-LL mismatch were significantly associated with ASD, and even with a single-level PLIF, appropriate SL and LL should be obtained at surgery to improve spinopelvic sagittal balance.
The Clinical Characteristics and Risk Factors for the Adjacent Segment Degeneration in Instrumented Lumbar Fusion
The results suggest that advanced age, anterior lumbar interbody fusion, and the restoration of the preoperative standing lumbAR lordosis may have a protective effect against the development of ASD.
Adjacent Segment Disease After Posterior Lumbar Interbody Fusion: Based on Cases With a Minimum of 10 Years of Follow-up
The majority of the reoperations for ASD were performed more than 5 years after the initial lumbar fusion surgery, although the progression of radiographical ASD began in the early postoperative period, and a high degree of pelvic incidence was a risk factor for developing early-onset radiographic ASD.
Radiographical Spinopelvic Parameters and Disability in the Setting of Adult Spinal Deformity: A Prospective Multicenter Analysis
Study Design. Prospective multicenter study evaluating operative (OP) versus nonoperative (NONOP) treatment for adult spinal deformity (ASD). Objective. Evaluate correlations between spinopelvic
The Influence of Pelvic Incidence and Lumbar Lordosis Mismatch on Development of Symptomatic Adjacent Level Disease Following Single-Level Transforaminal Lumbar Interbody Fusion
A high PI-LL mismatch is strongly associated with the development of symptomatic ALD requiring revision lumbar spine surgery, which may represent a global disease process as opposed to a focal condition.
Estimating the risk for symptomatic adjacent segment degeneration after lumbar fusion: analysis from a cohort of patients undergoing revision surgery
In patients re-operated upon for ASD, pelvic retroversion and hyperlordosis are the main mechanisms of compensation for the unbalanced spine.
Influence of postoperative sagittal balance and spinopelvic parameters on the outcome of patients surgically treated for degenerative lumbar spondylolisthesis.
Data in this study revealed that patient-rated outcome is influenced by the overall postoperative sagittal balance as defined by the SVA.
