42t-D/2.1   Greenstick fracture of the tibia

A greenstick fracture of the tibial shaft is classified as 42t-D/2.1.

A greenstick fracture is a combination of a complete fracture on the tension (convex) side and plastic deformity on the compression (concave) side.

The periosteum is disrupted on the convex side and remains intact on the concave side.

Greenstick fractures occur mostly in young children.
