Purpose Of Review: Fractures are frequently encountered in paediatric practice. Although recurrent fractures in children usually unveil a monogenic syndrome, paediatric fracture risk could be shaped by the individual genetic background influencing the acquisition of bone mineral density, and therefore, the skeletal fragility as shown in adults. Here, we examine paediatric fractures from the perspective of monogenic and complex trait genetics.
Recent Findings: Large-scale genome-wide studies in children have identified ~44 genetic loci associated with fracture or bone traits whereas ~35 monogenic diseases characterized by paediatric fractures have been described. Genetic variation can predispose to paediatric fractures through monogenic risk variants with a large effect and polygenic risk involving many variants of small effects. Studying genetic factors influencing peak bone attainment might help in identifying individuals at higher risk of developing early-onset osteoporosis and discovering drug targets to be used as bone restorative pharmacotherapies to prevent, or even reverse, bone loss later in life.

Adolescent Coronal Shear Fractures of the Distal Humerus: Surgical Approach and Outcomes.
J Hand Surg Am
January 2025
Department of Orthopaedic Surgery, Washington University School of Medicine, Saint Louis, MO. Electronic address:
Purpose: Isolated coronal shear fractures of the distal humerus in adolescents are rare injuries with unique surgical challenges. Respect for the posterior blood supply, open physes, and need for direct visualization to achieve anatomic reduction are critical considerations in surgical fixation. This study presents a case series and a surgical approach used in treating these patients.

J Pediatr Orthop
January 2025
Division of Sports Medicine, Boston Children's Hospital, Boston, MA.
Background: Anteroposterior (AP) and lateral radiographs often underestimate displacement in medial epicondyle fractures, further complicating the already debated operative indications. The radiocapitellar (RC) view is an alternative radiograph that allows for the separation of the humeroradial and humeroulnar joints. This study investigates the utility of the RC view in measuring displacement and identifying the need for operative intervention in pediatric medial epicondyle fractures.

Eur J Trauma Emerg Surg

Department of Orthopaedics and Traumatology, University Medical Center of the Johannes Gutenberg University, 55131, Mainz, Germany.
Purpose: The absence of evidence based general guidelines for radiographic follow-ups of pediatric diaphyseal forearm fractures treated with ESIN results in an arbitrary array of X-ray examinations. In most pediatric traumatology departments, an X-ray check is carried out 4 weeks after ESIN osteosynthesis of forearm shaft fractures to detect incipient consolidation of the fracture. However, the elevated sensitivity to ionizing radiation requires special precautions in the pediatric populations.

Microsurgery
January 2025
Pediatric Hand Surgery and Microsurgery Unit, Instituto de Investigación Sanitaria HM Hospitales, Barcelona, Spain.
Background: The periosteum is the main organ responsible for bone regeneration. Vascularized Periosteal Grafts (VPG) have demonstrated exceptional efficacy and speed in facilitating bone union among children with challenging bone healing conditions. Despite their promising results, the overall impact of these interventions has yet to be comprehensively evaluated through systematic review.

Bone turnover assessment and monitoring are essential for chronic kidney disease (CKD)-associated bone care. Patients with CKD suffer from significantly elevated fracture risk due to abnormally high or low bone turnover, which requires diametrically opposite treatments informed by patient-specific bone turnover data. However, a reliable, accessible, non-invasive bone turnover assessment and monitoring tool remains an unmet clinical need.
