1

Do boys or girls get injured more frequently?

Boys

2

The lower limb is more frequently fractured in children. T/F

False - upper limb

3

What is Wolf's law?

Bone adapts to load/stresses placed on it

4

What is Heuter Volkmann's law?

Compression inhibits growth and tension stimulates it

5

Children have a higher chance of healing normally than adults. T/F

True

6

What is a greenstick fracture?

One side of a bone is broken while the other is bent

7

What is a torus fracture?

Incomplete fractures of long bone shafts caused by axial pressure causing bulging of cortex

8

What is a bowing fracture/plastic deformation?

Incomplete fracture of a long bone causing bending

9

What are clinically suspicious signs of non-accidental injury?

Fractures in various stages of healing
Raised ICP in infants
Suspected intra-abdominal trauma in young children

10

How can children's fractures be investigated?

X-ray if ossified
Ultrasound
Arthrogram (joints)
CT/MRI (older children)

11

How are children's fractures managed?

Reduce (if needed), retain and rehabilitate

12

How accurately do children's fractures have to be reduced?

Not very as they have marked remodelling potential

13

How can the nerves of the arm be tested?

Radial - thumbs up
Ulna - star fish
Median - okay sign

14

What is the most common treatment of children's fractures?

Plaster of paris cast (followed by traction and less invasive fixation)

15

How are diaphyseal and metaphyseal fractures managed respectively?

Diaphyseal - joint above and below immobilised
Metapyseal - adjacent joint immobilised

16

When are children's fractures not managed conservatively?

Displaced intra-articular
Displaced physeal injuries
Open fractures
Polytrauma

17

What is the salter harris classification of physeal injuries?

Type 1 - complete physeal +/- displacement
Type 2 - physeal fracture extending through the metaphysis (chip metaphyseal fracture)
Type 3 - physeal fracture extending though the epiphysis
Type 4 - physeal fracture plus epiphyseal and metaphyseal fractures
Type 5 - compression fracture of the physis

18

When is external fixation indicated in children's fractures?

Contaminated wounds
