    Journal of Pediatric Orthopaedics · Jul 21 2026 · PubMed

    This systematic review of 13 studies found perfusion MRI has high sensitivity and NPV (90%) but modest specificity for detecting AVN of the femoral head in children, showing promise as a screening and prognostic tool pending higher-quality validation.

  11. The Relationship Between Boxer's Fracture and Aggression, Hyperactivity, and 2D:4D Finger Ratio in Children and Adolescents: A Prospective Case-Control Study.

    Journal of Pediatric Orthopaedics · Jul 21 2026 · PubMed

    This case-control study found children with boxer's fractures had lower 2D:4D finger ratios, higher aggression scores, and more ADHD symptoms, suggesting the injury may signal underlying behavioral/neurodevelopmental risk warranting psychosocial screening.

  12. How Much Meniscal Translation Is Normal? A Pediatric Physiological Arthroscopic Meniscus Mobility Study.

    Journal of Pediatric Orthopaedics · Jul 20 2026 · PubMed

    Arthroscopic study of 40 pediatric cadaver knees establishes normal age-based meniscal mobility and rim width benchmarks, showing the lateral meniscus is inherently more mobile than the medial, to help surgeons judge abnormal peripheral rim instability during discoid meniscus saucerization.

  13. An Assessment of the Preoperative Vitamin D Levels in Patients Undergoing Limb Lengthening Surgery.

    Journal of Pediatric Orthopaedics · Jul 16 2026 · PubMed

    In pediatric limb-lengthening patients, preoperative vitamin D deficiency was common (29%) but was not linked to worse bone healing index or higher complications, given routine postoperative supplementation.

  14. Trampoline Fractures in Children.

    Journal of Pediatric Orthopaedics · Jul 14 2026 · PubMed

    In this Finnish registry study, trampoline fractures showed age-dependent patterns—lower leg injuries in young children versus forearm fractures in older kids—with higher rates of open and surgically-treated fractures than other sports injuries.

  15. Does Substance Abuse Predict the Development of Mental Health Disorders in Adolescent Idiopathic Scoliosis Patients?

    Clinical Spine Surgery · Jul 13 2026 · PubMed

    AIS patients with substance abuse history had markedly higher odds of developing new mental health disorders (especially depression), suggesting a need for targeted preoperative screening.

  16. A Quality Initiative for Posterior Spinal Fusion in Adolescent Idiopathic Scoliosis (AIS): Liposomal Bupivacaine With Dexamethasone Use Results in Substantial Reduction in Inpatient Opioid Use.

    Journal of Pediatric Orthopaedics · Jul 13 2026 · PubMed

    In AIS spinal fusion patients, replacing PCA-based opioid regimens with liposomal bupivacaine plus dexamethasone markedly cut opioid use and shortened hospital stay without worsening pain control.
