New research

  1. STAC3D Against the Odds: Characterizing the Musculoskeletal Phenotype of STAC3 Gene Disorder.

    Journal of Pediatric Orthopaedics · Jul 24 2026 · PubMed

    STAC3 Disorder causes widespread musculoskeletal problems including scoliosis (83%), contractures (61%), and congenital foot deformities (61%), requiring early diagnosis and expectation management.

  2. Concurrent Validity of PROMIS-25 With PROMIS Pediatric Mobility in Pediatric Lower Extremity Trauma Patients.

    Journal of Pediatric Orthopaedics · Jul 23 2026 · PubMed

    PROMIS-25 correlated strongly with PROMIS Pediatric Mobility in pediatric lower extremity trauma patients, supporting its use as a broader multidomain outcome measure without losing mobility-specific sensitivity.

  3. Why it's better to believe in a larger definition of the diametaphyseal junction zone in pediatric distal radius fractures.

    Archives of Orthopaedic and Trauma Surgery · Jul 20 2026 · PubMed

    Diametaphyseal distal radius fractures in children exhibit characteristic biomechanical instability with ESIN that responds better to transepiphyseal intramedullary nailing fixation.

  4. Ulnar Epiphysiodesis for Distal Radius Physeal Arrest: Comparing Early Detection to Late Presentation Management.

    Journal of Pediatric Orthopaedics · Jul 16 2026 · PubMed

    Early detection and epiphysiodesis of premature distal radius physeal arrest produces similar functional outcomes to late presentation with deformity requiring corrective osteotomy.

  5. Correlation Between Radiographic Parameters and Clinical Range of Motion in Slipped Capital Femoral Epiphysis.

    Journal of Pediatric Orthopaedics · Jul 14 2026 · PubMed

    In slipped capital femoral epiphysis, percent epiphyseal displacement most strongly predicts flexion and abduction loss, while slip angle predicts internal rotation loss.

  6. Assessing Correlations Between PROMIS-25 and QuickDASH in Pediatric Patients With Upper Extremity Trauma.

    Journal of Pediatric Orthopaedics · Jul 14 2026 · PubMed

    PROMIS-25 correlates strongly with QuickDASH in pediatric upper extremity trauma, particularly for physical function; instruments show complementary ceiling and floor effects.

  7. Childhood Opportunity Index and Severity at Diagnosis of Developmental Dysplasia of the Hip.

    Journal of the American Academy of Orthopaedic Surgeons · Jul 07 2026 · PubMed

    Lower childhood opportunity index was not associated with age, severity, or treatment success of developmental dysplasia of the hip at a tertiary urban center.

  8. Risk stratification in conservatively treated pediatric lateral humeral condyle fractures: the prognostic value of articular gap and initial displacement - a retrospective cohort study.

    Journal of Pediatric Orthopaedics B · Jul 03 2026 · PubMed

    In conservatively treated pediatric lateral humeral condyle fractures, radiographic articular gap and initial displacement ≥2 mm predict displacement progression and complications.

  9. Venous thromboembolism in children with lower limb fractures: A systematic review and meta-analysis.

    Injury · Jun 03 2026 · PubMed

    Venous thromboembolism occurs infrequently in children with lower limb fractures at 0.53% rate; evidence for pharmacological prophylaxis remains sparse.

Recent reviews

  1. Surgical Management of Fibrous Dysplasia and Associated Syndromes.

    Journal of the American Academy of Orthopaedic Surgeons · Jun 09 2025 · PubMed

    Review covers surgical management strategies for fibrous dysplasia, noting bisphosphonates help early disease while strut allografts and angled blade plates show best long-term results for advanced deformities like shepherd's crook.

  2. Ipsilateral Healthy-segment Response to Leg Length Discrepancy.

    Journal of Pediatric Orthopaedics · Jan 01 2024 · PubMed

    Ipsilateral healthy segments show minimal growth changes in response to companion segment shortening from avascular necrosis, Legg-Perthès disease, or physeal trauma.

  3. Surgical Level Selection in Adolescent Idiopathic Scoliosis: An Evidence-Based Approach.

    Journal of the American Academy of Orthopaedic Surgeons · Apr 15 2023 · PubMed

    Surgical level selection in adolescent idiopathic scoliosis balances minimizing progression risk and optimizing spinal balance while fusing the fewest necessary levels.
