What is a common mechanism for olecranon fractures?

• A. Direct trauma to the elbow
• B. FOOSH with elbow extended
• C. FOOSH with elbow flexed
• D. Repetitive elbow use

Answer: (A)

The main idea is that olecranon fractures usually come from a direct blow to the elbow. The olecranon sits at the back of the elbow and is most likely to fracture when the elbow takes a direct impact, such as a fall landing on the posterior elbow or a direct strike. This direct trauma transmits a concentrated load through the triceps attachment at the olecranon, making a fracture more likely than other injury patterns from a FOOSH (fall onto an outstretched hand) or from repetitive use. While FOOSH can cause various elbow injuries (like radial head fractures or dislocations) and repetitive use tends toward stress-related issues, the classic and most common mechanism for an olecranon fracture is direct posterior trauma to the elbow.
