Adolescent competitive rhythmic gymnasts showed significantly higher scoliosis risk scores than healthy peers, supporting periodic scoliosis screening in this population during growth.
Spine Surgery Missions in Low-Resource Settings: Practical Considerations and Lessons Learned.
Drawing on experience from Jamaican spine surgery missions, this paper offers practical guidance on logistics, ethics, and partnership-building for successful surgical outreach in low-resource settings.
CT-based body composition phenotyping—especially a fat-infiltrated, muscle-atrophic pattern—predicted lumbar degeneration severity better than BMI, supporting its use for risk stratification.
In untreated mild-to-moderate idiopathic scoliosis, segmental rib index correlated with apical vertebral rotation (notably at T9-T11) more than with Cobb angle, suggesting SRI complements Cobb angle for assessing rotational deformity.
After THA for dysplastic hip osteoarthritis, residual pelvic obliquity is driven by leg lengthening in upward-tilted cases and by spinal deformity/reduced lumbar flexibility in downward-tilted cases.
In 408 patients with degenerative lumbar spinal stenosis, sarcopenic obesity independently predicted worse ODI scores, more severe disc degeneration, foraminal stenosis, and Modic changes, supporting routine SO screening in preoperative workup.
This meta-analysis found ACDF, PCDF, and laminoplasty yield similar neurological recovery for multilevel cervical myelopathy, but differ in pain, motion, hospital stay, and complications—guiding approach selection.
Standard screening criteria (abnormal exam, left-sided curve, hyperkyphosis) missed 34% of Chiari malformation/syrinx cases in operative pediatric scoliosis, arguing for broader preoperative MRI use.
Pelvic morphology decoupling from lumbar lordosis in chronic low back pain.
Chronic low back pain patients show a 'decoupling' of lumbar lordosis from underlying pelvic morphology, with pelvic retroversion and lordosis flattening representing a potential rehabilitation target.
In a multicenter cohort of Prader-Willi syndrome patients, spinal fusion achieved durable deformity correction but carried notable perioperative complication and reoperation risk, especially with higher BMI.
PROMIS scores show pediatric disc herniation patients have significant pain and mobility impairment, with surgery yielding faster symptom relief despite worse baseline function versus non-operative care.
Among 35 delayed anterior cervical revision cases, peri-plate gas on CT was highly specific (96.3%) for esophageal perforation, offering a useful red-flag to trigger targeted workup.
A systematic review of Japanese studies found DISH/L-DISH associated with higher reoperation and nonunion risk after lumbar degenerative surgery, but evidence certainty was very low and causality unproven.
In 108 degenerative lumbar scoliosis patients, short-segment standalone LLIF showed low early revision rates (8.3% within 2 years) with durable coronal correction, and revision risk was driven by age, not radiographic parameters.
In this 60-patient cohort, a conservative-first approach for giant extruded/sequestered lumbar disc herniation avoided surgery in 88% at 24 months, with rim enhancement on MRI showing potential (but not definitive) prognostic value.
In 401 adult spinal deformity patients, the T4-L1PA mismatch outperformed the SAAS specifically for predicting proximal junctional failure, suggesting restoring the T4-L1 relationship helps prevent this severe complication.
A national policy analysis found most insurers requiring smoking cessation before spinal fusion treat nicotine replacement therapy as equivalent to smoking, despite limited evidence it harms fusion outcomes.
In 328 ASD patients, postoperative C2 coronal angle ≤3.5° independently predicted better SRS-22/SF-36/NDI outcomes and outperformed C7-CSVL, suggesting it as a useful coronal alignment target.
Long-term qualitative interviews of adolescent idiopathic scoliosis patients after spinal fusion found most reported satisfaction and improved self-image, though some noted lasting activity restrictions and epidural difficulties in pregnancy.
Factors associated with U-type sacral fractures in geriatric patients: A retrospective cohort study.
In geriatric sacral fractures, spondylosis/spondylolisthesis, prior independent ambulation, and atraumatic mechanism independently predicted U-type (spinopelvic dissociation) morphology, identifying a distinct at-risk profile.
Machine-learning topic modeling of Spine Deformity's first decade shows growth in fusion outcomes, frailty/perioperative risk, and AI/LLM patient education research, while sagittal alignment and biomechanical topics have cooled.
Impact of GLP-1 Dose Intensity on Perioperative and Long-Term Fusion Outcomes Following ACDF.
In a large propensity-matched cohort, high-dose GLP-1 receptor agonists were no riskier than standard doses for perioperative complications or long-term fusion outcomes after ACDF, and both dose levels were linked to lower pseudarthrosis than no GLP-1 use.
Patients needing both lumbar fusion and total hip arthroplasty had delayed clinically meaningful recovery, but performing lumbar fusion before THA (rather than after) resulted in recovery timelines closer to THA-only patients.
In a large Japanese multicenter study, elderly patients with degenerative cervical myelopathy achieved clinically meaningful neurological improvement after surgery but had significantly less recovery of physical function and limb function than younger patients, underscoring the value of adding patient-reported outcomes to surgical assessment.
In this large database study, postoperative GLP-1 agonist use after ACDF was linked to lower rates of pseudarthrosis and dysphagia, suggesting timing-dependent benefits on fusion healing.
Cadaveric biomechanical testing showed lateral pedicle wall violation reduces screw anchorage strength, and redirecting these screws further weakens fixation rather than restoring it.
In a matched case-control study of 2603 PELD patients, smaller cross-sectional area and greater fatty infiltration of paraspinal muscles (psoas, multifidus, erector spinae) were associated with reoperation for recurrent disc herniation, suggesting preoperative muscle quality assessment could help predict recurrence risk.
This meta-analysis found stronger social support, including marital status, was linked to shorter hospital stays, fewer readmissions, and better outcomes after nontraumatic spine surgery.
An Introduction to Machine Learning for the Practicing Spine Surgeon.
This Clinical Spine Surgery article offers spine surgeons a practical primer on machine learning concepts, model design, and common pitfalls in interpreting AI-driven research.
Traditional regression-based risk scores remain competitive and trusted versus AI/ML models for spine surgery risk prediction, which still face validation and workflow integration barriers.
Modern Approaches and Time-Tested Methods in Managing Congenital Scoliosis in Children.
This review outlines current classification, bracing/casting, and surgical strategies (hemiepiphysiodesis, growing rods, hemivertebra excision, definitive fusion) for managing progressive congenital scoliosis in children.
This review outlines malpractice litigation trends in orthopaedic surgery, highlighting high-risk subspecialties and offering risk-management strategies like clear communication and thorough documentation.
Coronal Alignment in Adult Spine Surgery.
Review of coronal malalignment in adult spine surgery covering its causes, evaluation, functional impact, and surgical strategies to achieve proper coronal balance.
This review and single-institution case series discusses surgical management strategies for symptomatic, aggressive vertebral hemangiomas and proposes a treatment algorithm incorporating embolization, radiotherapy, and vertebroplasty.
A Delphi-based expert panel establishes consensus best-practice guidelines defining high-risk patients and standardizing prevention, diagnosis, and treatment of surgical site infection in pediatric spine surgery.
This review summarizes current uses of 3D printing in spine surgery (preoperative modeling, custom implants, screw guides) while noting long-term outcome data remain scarce.
This literature review found AIS patients typically return to sport 6-18 months after spinal fusion, with up to a third switching to lower-impact activities but no reported complications from RTS.
Meta-analysis of 722 patients shows S2AI screws yield less blood loss and fewer complications (reoperation, implant failure, infection) than iliac screws for sacropelvic fixation, making S2AI the preferable option.
