Galeazzi fracture is defined as: March 2013 (c)
**Core Concept**
A Galeazzi fracture is a type of fracture that involves both a fracture of the radial shaft and a dislocation of the distal radioulnar joint. It is a complex injury that requires precise reduction to achieve optimal outcomes.
**Why the Correct Answer is Right**
The Galeazzi fracture is named after the Italian surgeon Vittorio Galeazzi, who first described it in 1934. It is characterized by a fracture of the radius with dislocation of the distal radioulnar joint, often resulting from a fall onto an outstretched hand. The injury disrupts the normal anatomy of the forearm, leading to instability and potential complications if not properly managed.
**Why Each Wrong Option is Incorrect**
* **Option A:** A Colles' fracture is a different type of fracture that involves a displacement of the distal radius, but it does not involve a dislocation of the distal radioulnar joint.
* **Option B:** A Smith's fracture is a type of fracture that involves a displacement of the distal radius in the opposite direction of a Colles' fracture, but it does not involve a dislocation of the distal radioulnar joint.
* **Option C:** A Monteggia fracture is a type of fracture that involves a dislocation of the proximal ulna, but it does not involve a fracture of the radius or a dislocation of the distal radioulnar joint.
**Clinical Pearl / High-Yield Fact**
The Galeazzi fracture is a classic example of a fracture that requires precise reduction to achieve optimal outcomes. Failure to properly reduce the fracture and dislocation can lead to chronic pain, instability, and decreased function of the forearm.
**Correct Answer: C**
