  1. Radiology of Child Abuse Kristy Rollins, M-IV July 25, 2006 Radiology Clerkship

  2. Age at injury • 85% less than 3 years old • 69% less than 1 year old • Median age = 7 months

  3. Number of Fractures • 50% with single fracture • 21% with 2 fractures • 12% with 3 fractures • 17% with more than 3 fractures

  4. Most Common Location • Femur (35%) • Humerus (29%) • Skull (16%)

  5. Most Common Long Bone Fracture • Transverse fracture (48%) • Spiral fracture (26%) • Avulsion fracture (16%) • Oblique fracture (10%)

  6. Increased suspicion if . . . • Inconsistencies/discrepancies in story and injury • Unwitnessed injuries • Injuries blamed on siblings • Injuries inconsistent with patient’s developmental age • Injury inconsistent with mechanism given • On exam if areas in multiple areas of healing are noted.

  7. Workup of suspected abuse • Evaluation for: • Characteristic skin lesions • Swelling/deformity • Bone tenderness • Reluctance to use an extremity • Retinal hemorrhages • Trauma to the genitals • Signs of neglect

  8. Musculoskeletal Exam • Entire skin surface examined • Skeleton showed be examined for deformity • Check range of motion in all joints • Detailed neurological examination

  9. Radiographic Evaluation • Plain films of all areas of questioned present and previous injury • Skeletal survey • Consider radionucleotide scan as alternate to skeletal survey • Ultrasonography: useful for costochondral injuries • DEXA scan: can be used to differentiate OI and abuse

  10. Specific for Intentional Injury • Metaphyseal corner fractures • Posterior rib fractures • Fractures of sternum, scapula, or spinous processes • Multiple fractures in various stages of healing • Bilateral acute long bone fractures • Complex skull fractures

  11. Less Specific for Intentional Injury • Isolated long bone fractures • Simple skull fractures • Clavicle fractures

  12. Fracture healing & dating • Soft tissue changes • Usually apparent for several days • Due to inflammation • Periosteal bone formation • Detectable once calcified • Usually between days 7-14 after injury • Fracture gap widens • Necrotic bone resorbed • Peaks 2-3 weeks after injury

  13. Fracture Healing & Dating (2) • Soft callus • From production/calcification of osteoid • Appears as an increase in density • Hard callus • Lamellar bone bridges the fracture site • 1 week after soft callus • Usually completed healing at 3-6 weeks
