RESUMO
Pediatric seat-belt fracture is a rare condition, and its management has not been well defined. The authors report a case of pediatric Chance fracture that was managed conservatively and that demonstrated rapid bone healing. A 7-year-old boy presented with back pain after a motor vehicle accident. Plain lumbar spine radiography, three-dimensional computed tomography (CT), and magnetic resonance imaging revealed a seat-belt fracture type C (classified by Rumball and Jarvis), and the patient's condition was managed conservatively. The patient started to ambulate with a brace 2 weeks after the injury. Spine CT performed 100 days after the injury revealed a remodeled fracture, and dynamic radiography did not show any evidence of instability or kyphotic deformity. We suggest that if there are no neurological deficits or severe deformities, then a pediatric seat-belt fracture should be managed conservatively, because the bone healing process is far more rapid in children than it is in adults and because of possible growth problems after surgery.
