Medical neglect (2%)
Physical abuse (19%)
Sexual abuse(10%)
Psychologic maltreatment (7%)
Cutaneous injury is the most common injury due to abuse.
Skeletal trauma is the second most common manifestation of abuse.
Virtually every type and location of fracture has been documented in abused children. Fracture is documented in 11%–55% of physically abused children.
In a large series of abuse-related fractures,
76%: long bones
8%: skull
8%: rib cage
The American College of Radiology (ACR) and the Section on Radiology of the American Academy of Pediatrics recommend that a high-quality radiographic skeletal survey involve the use of a high-resolution imaging system, with technical factors designed to optimize image contrast and spatial resolution include an appropriate number of well-collimated views of each anatomic region.
