This is a rare injury.
If there is diagnostic doubt, screening by image intensification can be useful.
If this fracture is undisplaced and the patient and parents/carers are compliant, it can be managed with a removable splint, which is retained until symptoms resolve (2-3 weeks, depending on age).
Follow-up is not necessary, but parents/carers are advised to return if symptoms deteriorate or fail to improve over a period of 1-2 weeks.
Rapid return to normal function should be expected.
