Question

Identify the bone numbered in the X-ray below that most commonly fracture when a person falls on outstretched hands ?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The Correct Option is A

In orthopedic practice, a common scenario involves a person who falls on an outstretched hand, often referred to as a FOOSH (Fall On Out-Stretched Hand) injury. Among the bones in the wrist, the scaphoid bone (bone numbered 1 in the X-ray) is most commonly fractured in such cases. The scaphoid is one of the carpal bones located on the thumb side of the wrist, and its location makes it particularly vulnerable during a FOOSH injury.

Explanation: When a person falls and instinctively extends their hand to brace the impact, the force is transmitted through the wrist. The scaphoid, being in the direct pathway of this force and supported primarily by ligaments, is susceptible to fractures. These fractures can sometimes go unnoticed initially due to minimal swelling or displacement but can lead to complications such as non-union or avascular necrosis if unrecognized and untreated.

In conclusion, the correct answer is option 1 because this number corresponds to the scaphoid bone, which is the most commonly fractured bone in situations involving a fall on an outstretched hand.
