Lumbar Adjacent Segment Disease: A Modern Perspective and Review of the Literature.
This review updates understanding of lumbar adjacent segment disease as a multifactorial process driven by biomechanical and genetic factors, with risk increased by high BMI, preexisting adjacent-level degeneration, and poor sagittal alignment, while newer surgical techniques show mixed long-term benefit.
In over 5,000 pediatric spine deformity surgeries, abnormal baseline IONM data quality increased alert frequency and altered intraoperative management but did not worsen postoperative neurologic outcomes, supporting continued IONM use even with imperfect baselines.
In 22 patients, en-bloc thoracolumbar spondylectomy for spinal tumors achieved good oncologic control (5-year overall survival 64%) but high morbidity, with marginal margins seeming adequate while intralesional margins were linked to recurrence.
In this age/sex-matched study, anterior cervical spondylolisthesis was linked to advanced lower-level disc degeneration and sagittal imbalance, while posterior slippage showed degeneration at the slip level with more lordosis, suggesting disc degeneration pattern and sagittal compensation—not muscle or facet asymmetry—drive slippage direction.},{
Outcomes of Spinal Deformity Treatment in Asphyxiating Thoracic Dystrophy.
In this small case series, children with Jeune syndrome (asphyxiating thoracic dystrophy) safely underwent posterior spinal fusion for scoliosis with acceptable complication rates, supporting surgical correction despite their pulmonary complexity.
In a pooled RCT analysis of 187 patients, biportal endoscopic spine surgery was cost-effective compared to microscopic surgery for lumbar degenerative disease, with similar costs and QALYs but 95% probability of cost-effectiveness.
Impact of T4-L1-Hip Axis Normalization on Outcomes and Complications in Adult Spinal Deformity.
In long-segment ASD fusion, both under- and over-correction of T4PA-L1PA alignment increased mechanical complication risk, while normalization didn't improve patient-reported outcomes—pelvic fixation and comorbidities mattered more.
In 20 severe early-onset scoliosis patients, a hybrid single MCGR plus apical sliding rod construct improved and maintained coronal/sagittal correction while preserving spinal growth, though 35% needed unplanned revision surgery.
This study establishes MCID thresholds for objective gait speed, cadence, stride, and balance metrics after lumbar spine surgery, enabling more precise assessment of functional recovery.
In a randomized trial of 222 patients, adding triangular titanium implants above S2AI pelvic screws significantly reduced pelvic fixation failure (11% vs 20.4%) in multilevel spinal fusion without affecting alignment.
Analysis of 1,553 Reddit posts on SI joint dysfunction found 19% negative sentiment, especially around surgery and pain management, revealing gaps between published outcomes and patient expectations.
In anterior C4/5 cervical surgery, corpectomy and greater postoperative loss of vertebral height were independent risk factors for C5 palsy, informing safer decompression planning.
In a large propensity-matched cohort, preoperative GLP-1 receptor agonist use was linked to roughly 50% lower DVT risk and 43% lower 180-day mortality after lumbar laminectomy.
Meta-analysis suggests cement-augmented pedicle screws may lower hardware failure rates versus conventional fixation in metastatic spine surgery (4.3% vs 12.5%), but evidence certainty is low.
Qualitative interviews with AIS patients post-spinal fusion identified six psychological themes (anxiety, coping, peer support, meaning-making) supporting a biopsychosocial approach to perioperative care.
Spinal manipulation has reasonable evidence for acute-to-chronic low back pain as part of multimodal care, but weaker support for neck pain or extremity conditions, with rare serious adverse events and inconsistent safety reporting.
The Clinical Significance of the Lowest Instrumented Vertebra in Adolescent Idiopathic Scoliosis.
This review examines how choice of lowest instrumented vertebra in AIS fusion affects range of motion, return to sports, adjacent disk degeneration, and long-term clinical outcomes.
Comorbidity data collection across different spine registries: an evidence map.
A review of spine registries found highly inconsistent comorbidity data collection methods, underscoring the need for standardized indices to enable better outcome comparisons.
Non-coding RNAs in ossification of spinal ligament.
This review of 14 studies shows non-coding RNAs regulate osteogenesis and inflammation in spinal ligament ossification, offering potential biomarkers and therapeutic targets.
Osteoporosis and Spine Surgery: A Critical Analysis Review.
This review argues osteoporosis screening and multidisciplinary management should be routinely integrated into preoperative planning for spine surgery to reduce bone-density-related complications.
Ten techniques for improving navigated spinal surgery.
Outlines ten technical strategies to improve accuracy, efficiency, and safety during intraoperative navigated spinal surgery, covering positioning, screw placement, and instrumentation handling.
