A rare injury of distal radial and ulnar epiphysis.

Radial epiphyseal injuries are common. Ulnar epiphyseal injury is responsible for majority of cases of growth arrest and is commonly missed. The occurrence of associated ulnar epiphyseal injury is very rare and a concomitant type II injury of both radial and ulnar epiphyseal injury is also uncommon. A four-year follow-up of a 10-year-old boy with the above injury at right wrist is being reported in this article. At four years he has a negative ulnar variance but with excellent function and cosmesis.
