How Could A Child Still Move His Arm Despite Having A Mid-shaft Radius And Ulna Fracture?

Question: Hi, would it be possible to send you x-rays of my 6 month old son's fracture (mid-shaft radius/ulna) and for you to tell me what category of fracture it is, what is the likely mechanism and why it was still possible for him to move his arm without pain?
Many thanks
Many thanks
Brief Answer:
Shows simple undisplaced fracture through mid shaft of radius and ulna.
Detailed Answer:
Hello,
Uploaded X-ray shows simple undisplaced fracture through mid shaft of radius and ulna.
It may be due to fall with out-stretched hands.
Children's bony cortex are more elastic and it allows for more movement.
Since it is undisplaced, it allows movement without much pain.
Baby may need cast application over limb.
Get well soon.
Hope I have answered your query. Further queries are most welcome.

Many thanks for your reply.
Can I also ask is this fracture known as transverse/greenstick or both? Or other? How would it be classified specifically on a report?
Also, what type of force is likely to cause this, ie bending force, shear force? Can you see from the x-ray how much force was likely in this case?
Many thanks again

Brief Answer:
It is not possible to exactly comment on force.
Detailed Answer:
Hello,
Radius shows breach of cortex in both sides, so this is not true greenstick. Simply we can say simple transverse fracture.
It ulna, fracture appears to be greenstick.
It is not possible to exactly comment on force. It may be due to both fall with outstretched hands or direct blow.
