The Judet and Letournel classification divides acetabular fractures into elementary and associated patterns. The most common acetabular fracture pattern overall is:

• A Posterior wall fracture ✓
• B Anterior wall fracture
• C Transverse fracture
• D Both-column fracture

Explanation

Posterior wall fractures are the most common acetabular fracture pattern, typically occurring in dashboard injuries (knee-hip-knee vector) or posterior hip dislocations. They are treated surgically via the Kocher-Langenbeck approach when >40–50% of the posterior wall is involved, causing hip instability. Both-column fractures are the most common associated pattern but overall posterior wall is the single most frequent fracture type.
