What is the term for a Colle's fracture when it is associated with a distal radioulnar dislocation?

The condition in which a Colle's fracture is associated with a dislocation of the distal radioulnar joint is known as a Galeazzi fracture. This term specifically refers to the combination of a fracture of the distal radius along with the dislocation of the distal radioulnar joint, typically occurring due to a fall on an outstretched hand or trauma.

Identifying this fracture type is crucial for treatment planning and prognosis since the associated dislocation can lead to complications if not treated properly. Galeazzi fractures are considered more complex than a simple Colle's fracture alone, as they require careful consideration of both the bony and ligamentous integrity of the wrist.

The other options refer to different types of fractures or trauma: Smith’s fracture describes a fracture of the distal radius with palmar angulation; scaphoid fracture refers to a fracture of the scaphoid bone within the wrist; and a greenstick fracture typically involves a partial fracture that bends the bone without complete breakage, commonly seen in children. These definitions clarify why Galeazzi fracture is the correct term in the context of a Colle's fracture with a distal radioulnar dislocation.
