Hi, thanks for writing to HCM.
Based on the given description, I suspect that the bones might have united in a malposition (Malunion
) resulting in visible deformity
. If your son is less than 10 years old, there is a high possibility for the bone to remodel as the growth progresses and the deformity will slowly regress.
Generally there will be some amount of stiffness
after a cast removal and it will slowly regresses with physiotherapy
If he is more than 10 yrs of age and there is severe restriction of forearm movements, he may need a corrective surgery.
Hope this information is helpful. Good day
