The Scientific Program Committee received more than 1,000 abstract and session proposal submissions for this year’s Annual Meeting in Orlando. From those accepted, the 21 highest rated abstracts are being presented during three separate Best Paper sessions this week. Following are the Best Papers that will be presented today from 9–10 am in Room WF2.
Association between Adherence to Appropriate Use Criteria and Postoperative Outcome in Patients Treated For Lumbar Degenerative Spondylolisthesis
This retrospective analysis study aimed to use recently published Appropriate Use Criteria (AUC) to evaluate the appropriateness of surgery for lumbar degenerative spondylolisthesis in a large group of patients and to examine the association between adherence to the criteria and postoperative outcome.
Effect of Lumbar Spinal Fusion on Adjacent Segment Discs – An In Vivo Patient Study
In this prospective longitudinal study, researchers investigated the effect of fusion surgery on adjacent segment discs after a three-year follow-up using a precise and accurate in vivo imaging system under physiological weight-bearing conditions of the spine. The results were compared with age-matched healthy control subjects to isolate the normal age-related changes to these factors.
Adjacent Segment Degeneration after Lumbar Total Disc Replacement: 5-Year Results of a Multicenter, Prospective, Randomized Study with Independent Radiographic Assessment
This study is a post-hoc analysis of the activL IDE Trial in which investigators sought to determine the long-term rate of adjacent segment degeneration after lumbar total disc replacement to further support previous reports that have shown more than a threefold reduced rate of adjacent segment disease at five years versus lumbar fusion.
Effect of L4-Sacrum Fusion Alignment on Biomechanics of the Proximal Lumbar Segments in Sitting Postures
In this study, researchers sought to determine how different sitting postures alter the lumbosacral spinal alignment and what impact this has on the mechanical loading at proximal lumbar segments adjacent to L4-Sacrum fusion and, specifically, whether sitting postures after lumbar fusion surgery contribute to proximal junctional breakdown.
High Rate of Intraoperative Monitoring (IOM) Alerts in 176 Severe Pediatric Deformity Patients and its Relationship to the Deformity Angularity Ratio (DAR)
In this prospective observational multicenter cohort study, researchers analyzed the data of 176 pediatric patients with severe deformity (≥100°) or who were scheduled for a vertebral column resection in order to determine the relationship between different surgical procedures and radiographic measurements with intraoperative neural monitoring alerts and postoperative deficits.
The Feature of the Cardiac Function and Structure in Severe Thoracic Scoliokyphosis Patients — A Retrospective Study Based on the Echocardiographic and Holter Electrocardiograms
The purpose of this retrospective study was to evaluate the cardiac function and structure in severe thoracic scolikyphosis patients with major curve (>90°) by using echocardiographic and Holter electrocardiograms, and to offer preoperative data for surgery.
Mortality Rates Following Posterior C1-2 Fusion for Treatment of Displaced Type II Odontoid Fractures in Octogenarians: A 10-Year Review
This retrospective study aimed to analyze 30-day and one-year mortality rates, as well as the most common complications associated with posterior C1-2 fusion, to determine if surgical intervention is a viable option for treatment of unstable Type II odontoid fractures in patients 80 years of age or greater.
