What is the diagnosis for a fracture of the distal radius with disruption of the distal radioulnar joint?

The diagnosis of a fracture of the distal radius accompanied by disruption of the distal radioulnar joint is known as Galeazzi's fracture. This injury typically involves an unstable fracture of the distal radius, which can occur due to a fall on an outstretched hand, along with an associated dislocation or injury to the distal radioulnar joint. The combination of these injuries alters the anatomy and biomechanics of the wrist and forearm, necessitating surgical intervention to restore proper alignment and function.

In the context of this question, Galeazzi's fracture is significant because it highlights the importance of considering both the fracture and the joint stability when diagnosing wrist injuries. Other injuries may involve fractures but do not typically include the specific combination of a distal radius fracture with distal radioulnar joint disruption, which distinctly characterizes Galeazzi's fracture. Understanding this helps differentiate it from conditions like mallet finger, which involves an injury to the extensor tendon, boxer’s fracture, which specifically refers to a fracture of the fifth metacarpal, and Monteggia's fracture, which involves an ulnar fracture with radial head dislocation.
