Long bone fractures at the infant growth plate, known as classic metaphyseal lesions (CMLs), raise a strong suspicion for abusive injury. CMLs persist as a hallmark for inflicted injury although a handful of documented cases of CMLs created by other, non-abusive mechanisms within various healthcare settings are scattered throughout the past few decades of medical literature. The forces required to sustain a CML are typically defined as a combination of tensile, compressive, or rotational energy applied to the metaphyseal regions of an infant's long bones. Recently, two separate child protection teams each encountered a case of CML discovered after reported motor vehicle collisions (MVC). This provoked a critical appraisal of the medical literature to inform clinical practice regarding MVCs as a potential mechanism for this fracture type and to remind clinicians that there is no single injury pathognomonic for abuse.
