At what age should you consider reducing a plastic deformity of the radius or ulna?

Considering the management of a plastic deformity of the radius or ulna, it is essential to recognize the differences in skeletal maturity and healing potential among children at various ages. For children over 4 years old, the skeletal system is generally more developed than in younger children, making it more appropriate to consider reduction in cases of plastic deformity.

In younger children, specifically those under 4 years old, the bone remodeling potential is significant, which means that many deformities may resolve naturally over time as the child grows. This is less predictable in older children, where the risk of permanent deformities increases if the plastic deformity is not addressed. Thus, reducing plastic deformities in children over 4 years old is recommended to prevent functional limitations and to ensure proper alignment as they approach maturity.

The other age ranges either fall below the recommended threshold for intervention or do not accurately reflect the increased risk associated with age-related factors, emphasizing the importance of timely intervention when the child has passed the age of 4.
