What is the location of a boxer's fracture?

Neck of the first metacarpal
Neck of the fifth metacarpal
Base of the third metacarpal
Distal phalanx of the index finger

The correct answer is: Neck of the fifth metacarpal

The boxer's fracture specifically refers to a fracture of the neck of the fifth metacarpal, which is the bone that corresponds to the little finger. This type of fracture commonly occurs when someone punches an object, often leading to a downward angulation of the fracture at the neck. The mechanism of injury typically involves forceful impact with a clenched fist. The other potential locations mentioned do not align with the characteristic injury associated with boxer's fractures. For example, the neck of the first metacarpal pertains to the thumb, while the base of the third metacarpal and the distal phalanx of the index finger refer to different areas of the hand which are not involved in this specific type of injury. Thus, the identification of the neck of the fifth metacarpal as the site of a boxer's fracture is accurate and reflects the common understanding of this type of injury in radiography and orthopedic contexts.
