- child abuse occurs most often under the age of 3 years;
- when child abuse goes unrecognized, the mortality rate may be as high as 5%;
- common patterns for abuse:
- unwitnessed spiral fractures
- fractures occuring prior to walking age;
- common fractures:
- rib fractures: the most commonly found fractures in child abuse (followed by humerus, femur, and tibia);
- femur fracture: the majority of femur frxs in infants are due to abuse;
- skeletal survey: indicated to determine if there are other fractures in different stages of healing;
- differential dx:
- osteogenesis imperfecta
- note that w/ some OI phenotypes, radiographic osteopenia may be slight and may be missed on x-ray;
- in these cases, consider dual energy x-ray absorptiometry;
- The role of dual energy x-ray absorptiometry in aiding the diagnosis of pediatric osteogenesis imperfecta.
