Rapid Healing and Remodeling Process of Pediatric Seat-Belt Fracture without Surgical Treatment / 대한신경손상학회지

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.

The Incidence of Pediatric Trampoline Injury: Statistics from a Single Institution / 대한정형외과학회잡지

PURPOSE: Recently, there has been increasing number of trampoline injuries at our pediatric orthopedic clinic and emergency room. Therefore, this study is to analyze the prevalence of the trampoline injuries with emergency room surveillance. MATERIALS AND METHODS: Between September 2015 and February 2017, all patients under the age of 15 years, who visited emergency room of a teaching hospital with trauma and referred to the department of orthopedic surgery, was included; the cause of trauma was analyzed. The severity of injury was also evaluated and compared according to the cause of injury. RESULTS: There were a total of 1,807 patients under the age of 15 years who visited our emergency room during the study period. There were a total of 71 trampoline injuries (3.9%). There were 28 patients below the age of 5 years, and among them, 14 minor injury were recorded; 43 patients were over the age of 5 years and with 4 minor, 20 moderate, and 19 severe injuries. In the age between 5 and 15 years, the prevalence of mild injury was lower in trampoline injury compared with those of other sports injuries (9.3% vs. 34.0%) and the prevalence of severe injury was higher in trampoline injury (44.2% vs. 26.3%) (p=0.002). CONCLUSION: Our findings indicate that the incidence of trampoline injury was lower than other country, but it was more severe than injuries from other sports. With increasing incidence of trampoline injuries, parents should be more mindful that trampolines are not safe and stricter supervision may be necessary.
