[Fracture-separation of the distal humeral epiphysis in a four-month-old infant: case report]
Insights
This case study details the successful treatment of a distal humeral epiphyseal separation in an infant. Advanced imaging and minimally invasive techniques ensured an excellent long-term outcome for pediatric fracture care.
Area of Science:
- Pediatric Orthopedics
- Pediatric Trauma Surgery
Background:
- Distal humeral epiphyseal separations are rare in infants.
- Accurate diagnosis and timely intervention are crucial for optimal outcomes.
Observation:
- A 4-month-old infant presented with a fracture-separation of the distal humeral epiphysis.
- Diagnosis was confirmed via X-ray, with further evaluation using computed tomography (CT) and magnetic resonance imaging (MRI).
Findings:
- Ultrasound-guided closed reduction was performed.
- Percutaneous osteosynthesis with Kirschner wires was utilized for fracture stabilization.
- The fracture healed successfully with an excellent outcome at 23 months post-injury, despite a prolonged immobilization period due to a respiratory infection.
Implications:
- This case highlights the successful application of minimally invasive techniques in managing complex pediatric elbow fractures.
- The use of advanced imaging modalities aids in precise diagnosis and treatment verification.
- Early intervention and appropriate management can lead to excellent long-term functional recovery in infants with physeal injuries.
Abstract:
We report the case of a 4-month-old infant with fracture-separation of the distal humeral epiphysis diagnosed on the basis of X-ray examination. Closed reduction was performed under ultrasound guidance. The effect of reduction was checked by computer tomography and magnetic resonance imaging and, under general anaesthesia, the arm was immobilised using a collar-and-cuff. Subsequently, percutaneous osteosynthesis with two 1.2-mm Kirschner wires through the radial condyle was carried out. The fracture was allowed to heal in a normal elbow position with plaster cast for 5 weeks. The duration of immobilisation had to be prolonged and removal of the wires postponed because the infant acquired a respiratory infection; the usual time for fracture union is 3 weeks. At 23 months after injury the outcome was excellent and the baby remained registered for a long-term follow-up.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
