Galeazzi - Equivalent Pronation Type Injury with Splitting of Ulnar Epiphyseal Plate into Two Fragments - A Rare Case Report and Review of Literature.
BACKGROUND
In children and adolescents distal forearm physeal fractures are common. Usually distal forearm physeal injuries of are common injuries in children and adolescents. Epiphyseal injuries to the distal radius are common in children, but involvement of the distal ulna is rare. Fracture of the distal radius with dislocation of the DRUJ is known as a True Galeazzi fracture dislocation and an epiphyseal separation of the distal ulna occurred instead of dislocation of DRUJ or both)[10] is called Galeazzi equivalent lesions. Galeazzi fractures in children are less common than in adults. [4] These injuries are uncommon and there are few descriptions of them in the current literature.


METHODS
Here we report the case of a 13-year-old boy, student with history of RTA presented with pain and swelling of distal forearm diagnosed with closed injury of Galeazzi equivalent type. Here injury to the distal ulnar epiphyseal plate is in the form of epiphyseal separation (Salter Harris type I / Peterson type III) with splitting of epiphysis into two fragment - [ulnar styloid & radial side of ulnar epiphyseal plate] (Salter Harris type III / Peterson type IV) with fracture of metaphysis of lower end radius (Peterson type I) without neurovascular deficit. Patient was given surgical treatment in the form of closed reduction and K-wire fixation for fracture of distal radius and open reduction using extended ulnar approach and fixation with K-wire for ulnar epiphyseal fracture as closed reduction was not possible due to soft tissue interposition.


CONCLUSIONS
Galeazzi equivalent injury is rare. It may require radiographic comparison of opposite uninvolved distal forearm with wrist, CT or MR imaging to define injury accurately. It may also require open reduction for anatomical or acceptable reduction of fracture to minimize chances of growth arrest which may occur as a complication of injury. It is also necessary for frequent follow up to identify complication early especially growth arrest in asymptomatic patient.
