Incidence, age

• Incidence UK (Barlow et al. Lancet

2000)

– 2.5 per 10 000 children younger than

1 year (95% CI 14.9-38.5)

Clinical Presentation

• Unexpected soft tissue swelling

• Seizures/Collapse

• Irritability

• No history of a trauma…….

Recommended imaging in children

< 2-3yrs of age

• Head CT

• Skeletal survey (within 24 hrs, or asap)

• If findings on head CT, or if pos. neurology; add a MRI, including the spinal canal

• If positive MRI; repeat head CT on day 10, + FU MRI (after 2-3 months – 6-12 months)

• If abdominal trauma; abdominal CT

• In children older than 2-3yrs; individual imaging strategy

Head CT

Skeletal survey

• Skull (AP and lateral: Townes if ? occipital fracture)

• Spine (lateral views cervical, thoracic + lumbar)

• Chest (AP + oblique views both sets ribs)

• Abdomen, pelvis and hips (AP)

• Long bones (AP views both humeri, both rad/ulna, both femora and both tib/fib)

• Hands (DP)

• Feet (AP)

• Coned views of suspected abnormality d/w supervising Consultant Radiologist

Ref.: ESPR Task Force on Child Abuse: www.ESPR.org

Skeletal survey - standards

• Technical requirements for technique – small focal spot,

– suitable computed radiography systems (including standard resolution imaging plates) may be used for skeletal surveys if they have dedicated paediatric software

• Personnel requirements – Radiographers trained in paediatric radiography techniques

should perform skeletal surveys in children

– Appropriately trained radiographic staff must be available in all radiology departments where children are imaged

• Procedural standards

Ref.: ESPR Task Force on Child Abuse. www.ESPR.org

Additional, initial imaging

• CT chest if suspicion of rib fractures

Ref.: ESPR Task Force on Child Abuse: www.ESPR.org

Scintigraphy

• High sensitivity new rib fractures

• Low sensitivity skull fractures

Ref.: ESPR Task Force on Child Abuse: www.ESPR.org

MRI

• Low sensitivity for metaphyseal injury

and rib fractures

Imaging- follow-up

• Repeat skeletal survey (except for skull,

pelvis, lateral spine) after 2 weeks

Ref.: Harper NS, Eddleman S, Lindberg DM et al. The Utility of Follow-

up Skeletal Surveys in Child Abuse. Pediatrics 2013; 131; 672-

The role of imaging is to answer the

following Q:

• Q1: Is there skeletal injury, and if so, are

there specific features suggestive of NAI?

• Q2: …….evidenced by?

• Q3: Most likely mechanisms – evidence?

• Q4: How old is the fracture - evidence?

• Q5: If the injury is suspicious of NAI – what

other options are there?

Skeletal injury in NAI

• Ribs (26%)

• Metaphysis (23%)

• Long bones (36%)

• Skull (15%)

Ref.: Carty H. Eur Radiol 1997; 7(9); 1365-1376

Skeletal injury; «specificity» for NAI

• High

– Methaphyseal lesions

– Rib fractures, particularly posterior

– Scapular, spinous process and sternal fractures

• Moderate

– Multiple fractures, especially bilateral

– Fractures of different ages

– Epiphyseal separations

– Vertebral body fractures and subluxations

– Digital fractures

– Complex skull fractures

Skeletal injury; «specificity» for NAI

• Low (but common)

– Subperiosteal new bone formation

– Clavicular fractures

– Linear skull fractures

Rib fractures

• costovertebral articulations

• costochondral junctions and anterior rib

ends, lateral fractures

• often multiple and bilateral

• may be clinically silent

Rib fractures

Issues

• Acute rib fractures difficult to diagnose:

– Use the best available XR technique

– Additional CT on the same day or repeat XR in 12-

14 days?

kV 64, mA 2.0 kV 62, mA 3.0 kV 60, mA 3.2

Classic metaphyseal lesion (CML)

• fracture along the primary

spongiosa of the metaph.

• tibiae, distal femur and

proximal humerus often

bilateral

• minimal or no periosteal

reaction

• heal without callus

formation

• may be clinically silent

Ref.: Kleinman et al.

Classic methaphyseal lesion

• rotation / traction

Issues

• Positioning!

• Differentiation between injury and

physiological irregularities

– additional views, high-res.

– repeat x-ray in 10-12 days, or 4-6

weeks

Male, 8 months, subdural haematoma

Long bones

• Femur and humerus most common

– femur

• midshaft

• transverse / spiral / oblique

• (no differences between NAI and accidental)

– humerus

• midshaft, but also supracondylar

Long bones

• spiral fracture = twisting

force

• oblique fracture =

levering (e.g. lifting a

child by a limb)

• transverse fracture may

be the result of a direct

impact, a greenstick or

buckle fracture will be

caused by

compression, e.g. a fall

Issues

• ”physiological” periosteal reaction

– < 3-4 months of age

– most often symmetrical

– <2mm

Skull fractures (15%)

Skull fractures

“the shaken infant – (impact) syndrome” (Caffey)

Skull Fractures

Accidental

• Simple linear

“hair-line”

unilateral parietal

Non-Accidental

• Wide (> 5mm)

• Fissured

• Non-Parietal

• Crossing Sutures

• Affecting + one

bone

• Depressed

• Growing

and the diagnosis of abuse; Arch. Dis. Child. 59:246-252.

Fracture healing - dating

• Dating of fractures is of medico legal

importance

• Most radiologists date fractures based on

their personal clinical experience

• Few studies

1) A timetable for the radiologic features of fracture healing in young children. Prosser I,

Lawson Z, Evans A, Harrison S, Morris S, Maguire S, Kemp AM. AJR Am J Roentgenol.

2012 May;198(5):1014-20.

2) How old is this fracture? Radiologic datin gof fractures in children: a systematic review.

Prosser I, Maguire S, Harrison SK, Mann M, Sibert JR, Kemp AM.

AJR Am J Roentgenol. 2005 Apr;184(4):1282-6. Review.

Fracture healing

• SPNBF

– Early: 4-10 d

– Top: 10-14 d

– Late: 14-21 d

Fracture healing

• Endosteal callus

formation

– Soft

• 10-14 d (early)

• 14-21 d (peak)

– Hard

• 14-21d (early)

• 21-42d (peak)

• 42-90 d (late)

Kleinman 1998.

Fracture healing

• fractures in young children may be dated as

acute (< 1 week), recent (8-35 days), or old (≥

36 days) on the basis of the presence of six

key radiologic features in combination

• good interobserver agreement suggests

these results are reproducible

A timetable for the radiologic features of fracture healing in young

children. Prosser I, Lawson Z, Evans A, Harrison S, Morris S,

Maguire S, Kemp AM. AJR Am J Roentgenol. 2012

May;198(5):1014-20.

Differentials

1. Birth trauma (most common clavicle,

femur and humerus). The absence of

callus 11 days or more after birth

excludes a birth-related injury

2. Accident

3. Bone disorder
