What is a common name for a fracture of the 4th or 5th metacarpal neck?

A fracture of the 4th or 5th metacarpal neck is commonly referred to as a Boxer's fracture. This type of fracture typically occurs when someone punches an object, leading to a break at the neck of the metacarpal bone. The mechanism of injury often involves axial loading during a closed fist impact, causing the bone to break at its weakest point—the neck region.

The name "Boxer's fracture" specifically derives from its frequent occurrence in boxing and similar sports where punches are thrown. Clinically, it is essential to recognize this fracture because it can affect hand function and may require specific treatment to ensure proper healing and restoration of grip strength.

Other fractures mentioned, such as Smith's fracture, are characterized by a fracture of the distal radius with palmar angulation, generally resulting from falling on an outstretched hand. Colles' fracture, similarly related, also pertains to the distal radius but is distinguished by dorsal angulation and is commonly seen in wrist falls. Meanwhile, a Greenstick fracture refers to an incomplete fracture seen primarily in children, resembling the way a young tree bends but does not fully break. Understanding these distinctions helps in accurate diagnosis and management of hand and wrist injuries.
