43t-E/8.1   Osteochondral fractures (intraarticular flake) of the distal tibia

Intraarticular flake (osteochondral) fractures of the distal tibia are classified as 43t-E/8.

These injuries are more common in adolescents. They are caused by rotation of the talus compressing the articular surface of the tibia (although the flake is more often on the talar articular surface).

Small fragments may be difficult to identify on a plain x-ray.

MRI is the imaging technique of choice to identify and assess these injuries.
