The risks of treatment with a plaster cast are that the injured wrist might not look the same as the other arm, healing may take longer and in rare cases, if the arm does not grow straight an operation may be required.

The risks of surgical treatment are that the bone may still move out of place, and in those who have an operation, an infection may sometimes occur.

Children in both groups are at risk of irritation related to the cast, pressure areas and a condition related to muscle swelling called compartment syndrome, though the risk is likely to be greater in the group who get a procedure or operation.
