During medicolegal proceedings in cases of suspected child abuse it is sometimes argued that skull fractures could be sequelae from complications at birth or resulted from a prior witnessed accidental trauma that may have preceded the suspected abusive event. There is paucity of scientific evidence indicating timing for skull fracture healing in children up to 36 months old. Objective of this study was to assess the average time to imaging documentation of skull fracture healing in children up to 36 months old. We performed retrospective chart review and image analysis in children with documented skull fractures after trauma between May 2009 and December 2014, excluding any patients who underwent cranial procedures related to the head injury, patients with pre-existing CSF shunts, patients who were referred for child abuse evaluation, and patients who were admitted to the General Surgery service for multi-organ trauma.We analyzed 185 skull fractures: 82 fractures were not healed, 49 fractures were partially healed, and 54 fractures were healed on follow-up imaging. The mean time to imaging evidence of healing among patients with healed fractures was 108 days (3.6 months), the median was 112 days (3.7 months), the minimum was 22 days, and the maximum was 225 days (7.5 months). Chi-square analysis showed a significant relationship between the skull fracture healed status and presence of bleed (P = 0.001) and with fracture characteristics of displaced, depressed, or dehiscent (P= 0.009). There was no significant association with the age group (P= 0.32) nor with involvement of multiple cranial plates (P= 0.73). This information may be useful during medicolegal proceedings in patients with suspected abusive head trauma mechanism.
