Four-year review of burns as an etiologic factor in the development of long bone fractures in pediatric patients.
Reduced bone density has been documented in children after burns. This loss of bone may place children at heightened risk for fractures. The medical records of all acutely injured patients with burns in excess of 40% TBSA burn admitted to our institution between January 1, 1997, through December 31, 2000, were reviewed for fracture incidence. Patients with fractures sustained during the course of initial trauma were not included in the review. One hundred four records were reviewed. These patients had a mean age of 6.7 +/- 0.51 years, (range, 0.2 to 18.0) and a mean %TBSA burn of 59.9 +/- 1.60 (range, 40 to 98) with a mean full-thickness %burn of 51.7 +/- 2.16 (range, 0 to 95). Fifteen long bone fractures were documented in six patients during the review time frame. All fractures were initially suspected by physical therapy personnel upon regularly scheduled therapy sessions and subsequently verified by x-ray. All fractures identified by this review occurred in children less than 3 years of age. Most fractures were noted during the rehabilitation phase of injury (range, 73 to 283 days after burn) once wounds were more than 95% healed, except for one child, who sustained multiple fractures during the acute recovery phase at a referring hospital. A 5.8% incidence of fractures was noted in patients with burns in excess of 40% (6 of 104 admissions). The etiology of the fractures is unknown, although the hormonal milieu postburn, depressed vitamin D status, inadequate protein intake, and decreased weight-bearing activity are potential contributory factors. In addition, infants and toddlers tend to provide more resistance to therapy because of an inherent lack of cognition. This may account for the increased breaks in this population.
