Results

The following is a summary of the systematic review findings up to the date of our most recent literature search. If you have a specific clinical case, we strongly recommend you read all of the relevant references as cited and look for additional material published outside our search dates.

 

Of 540 studies reviewed, 18 studies addressed which children should be investigated for occult fractures when child abuse is suspected 1-18

  • Study design:
    • 5 case series 1,2,6,7,13
    • 10 cross-sectional 3-5,8,10,12,14-16,18
    • 2 uncontrolled before and after study 9,17 
    • 1 cohort study 11
  • Age range: 0 – 16 years (the majority were aged less than two years)
  • Gender: the rate of positive SS was not analysed by gender

 

Influence of ethnicity and socio-economic group

  • African/American infants with unwitnessed head injury were more likely to have a SS than white infants (90.5% v 69.3%, p=0.01) 17. Non-white or hispanic children or those without private insurance were more likely to undergo screening 9,14 
  • White children with private insurance were much less likely to have a SS than white children with no insurance/government insurance (50% v 88%, p<0.001) 17,18
  • Introduction of a screening guideline reduced the inequities in SS conducted in white versus African/American children (rates of SS in white children increased from 69.3% to 84.6%, (p=0.05) but stayed the same among African/American children) 9,17 

 

Details of included studies

Influence of age on fracture detection

  • The diagnostic yield from SS correlates inversely with age and is significant for children under two years of age 1,2,4,5,8,12,13,16 
  • The rate of occult fractures detected in children aged less than two years in two large-scale studies was 10% – 13% 4,10,13
  • There is a higher diagnostic rate for SS in children under six months than in those aged two years and six months 4
  • Two studies showed no difference in the yield of occult findings on SS in those aged less than one year and those aged one – two years 6,13
  • Significantly more rib fractures 7 and classical metaphyseal lesions 7,13 were found in children aged less than one year than those aged one – two years 
  • 14/17 (82%) of positive SS were in children less than one year of age 2
  • 14/55 (25%) of children aged less than one year had positive SS 2
  • Only 2/7 (29%) of children aged between one and two years had positive SS (personal correspondence) 2

Screening siblings/household contacts

  • Six skeletal surveys were performed on siblings (< three years old) of children with abuse. SS was positive in one sibling 2
  • 134 household contacts aged less than two years underwent a SS. 16/134 had fractures, 9 of whom were aged less than six months 15
  • Half of these children had an isolated fracture and half multiple fractures, none of which had clinical signs 15
  • 9/16 twins had fractures on their SS giving an odds ratio of 20.1, 95% CI 5.8-69.9 for identifying a fracture in a twin of an abused child 15.  Of 75 twin triplet siblings screened, twins were more likely to have an occult fracture identified than non-twins 14

 

Indications for SS

  • 14% of children with abusive burns had occult fractures identified on SS 6,8
  • Mean age of children with positive SS and burns was older than non-burns cases (p=0.03) 8
  • Fractures in children with burns included rib, CML, long bone, skull, and clavicular 6

 

  • 29% of infants aged less than one year with an unwitnessed head injury had positive findings on SS warranting child protection investigations 17
  • If the injury severity score was >15, cases were more likely to have positive findings than those with lower scores (OR 3.4, p<0.01) 17
  • Abusive head trauma (AHT) was significantly associated with a positive SS (P<0.00) 4
  • Three children presenting with an isolated skull fracture and no other signs of abuse had a positive SS 4
  • 86% of children aged less than 18 months presenting with an isolated skull fracture underwent SS, of whom 6% had an additional fracture identified. Only one of nine with additional fractures was aged more than 6 months, eight of nine had a simple skull fracture 11
  • Of 201 children less than one year of age presenting with skull fracture and a normal GCS, 12 had further fractures (5.5%) 3
  • 141 infants aged less than one year presenting with a skull fracture (non-MVC) underwent SS with only two identifying additional fractures. Each had risk factors for child abuse. Additional fractures were lower limb metaphyseal fractures 18

 

  • Children presenting with apparent life threatening event (ALTE) / apnoea had a higher rate of positive SS than those presenting for other reasons (p=0.05) 4
  • Children presenting with seizure had a higher rate of positive SS than those presenting for other reasons (p=0.02) 4
