BackgroundSkull fractures are commonly seen after both accidental and nonaccidental head injuries in young children. A history of recent trauma may be lacking in either an accidental or nonaccidental head injury event. Furthermore, skull fractures do not offer an indication of the stage of healing on radiologic studies because they do not heal with callus formation as seen with long bone fractures. Thus, a better understanding on the timing of skull fracture resolution may provide guidance on the medical evaluation for accidental or nonaccidental head injury.ObjectiveThe aim of the study was to determine the time required for radiographic skull fracture resolution in children younger than 24 months.MethodsThis was a retrospective observational analysis of children younger than 24 months referred with skull fractures between January 2008 and December 2012. Analysis included children with accidental head injuries with a known time interval since injury and a negative skeletal survey who underwent serial radiographic studies. Complete healing of a skull fracture was defined as resolution of fracture lucency by radiograph.ResultsOf the 26 children who met inclusion criteria, 11 (42.3%) demonstrated resolution of skull fracture(s) on follow-up imaging. Fracture resolution on radiologic studies ranged from 2 to 18 weeks. Twelve fractures in 10 children demonstrated fracture resolution at 10 or more weeks after injury.ConclusionsHealing or resolution of a skull fracture can take months in children younger than 24 months. With the high variability in skull fracture presentation and large window to fracture resolution, unexplained or multiple skull fractures in children younger than 24 months may be the result of a single or multiple events of head trauma.Copyright © 2020 The Author(s).
