- Fracture is defined as a break in the continuity of bone.
- Children are not little adults. Paediatric bones are more elastic than adults. Their bones deform for a slightly longer time before they break. The injury patterns vary, in contrast to adults, and within the different paediatric subset, depending on skeletal age.
- Partial injuries are peculiar to children – called Greenstick fractures. These are incomplete fracture patterns. These fractures do not traverse the entire cortical thickness as the unbroken part undergoes just a plastic deformation.
- Fracture healing follows a similar pattern but is much faster than adults as the dynamics of blood supply are better. Attempts to re-align the fractures (manipulations) are easier within two weeks from injury as the fractures would begin to mal-unite in the deformed position after that period.
- The fundamental difference in the anatomy of growing bones to adult bones is the presence and injuries around the growth plates or physis (plural - physes). Physeal fractures can result in growth abnormality if not managed appropriately - there is a low threshold for surgical intervention.
- All fractures in children should raise the possibility of Non-Accidental Injury (NAI).
NON – ACCIDENTAL INJURIES (NAI) and FRACTURE
In the context of fracture, suspect NAI if there is:
- Any fracture before walking age.
- Inconsistent history (i.e. the history 'doesn’t fit' the injury pattern).
- Inconsistent explanations (between parents /carers).
- Delayed presentation.
- Bruising patterns on the child.
- Long bone injury with head injury.
- Retinal haemorrhages.
- Misfitting fracture patterns such as :
- Transverse fracture in long bone.
- Metaphyseal corner fractures / Bucket handle fracture also known as Classical Metaphyseal Lesion.
- Rib fractures (Posterior ribs or at costochondral junctions).
- Skull fractures (depressed skull fractures or non-parietal skull fractures).
- Fractures at varying stages of healing on skeletal survey.
Priority is to place the child in a safe environment (i.e. admit the child to the ward) and seek assessment of a paediatrician to exclude life threatening injuries, nutritional status and social circumstances, to rule out sexual abuse and ensuring safety of the child.
