The Lauge-Hansen classification is determined by what aspect of ankle injuries?

• A. Time since injury
• B. Pain level
• C. Soft tissue status
• D. Mechanism of injury

Answer: (D)

The key idea here is that Lauge-Hansen classification is built around how the injury happened, not when it was sustained or how it feels afterward. It categorizes ankle fractures by the mechanism of force and the resulting sequence of ligament and bone disruptions. Different mechanisms—like a foot turning in while the leg stays planted vs a twisting with the foot rotating in a different direction—produce predictable patterns of injury, such as which ligaments tear first and which bones fracture next. That mechanism-based pattern helps clinicians anticipate other damaged structures and choose appropriate imaging and treatment. So, this classification is about mechanism of injury, not time since injury, pain level, or soft tissue status. Time, pain, and soft tissue condition influence management decisions, but they do not define the pattern used in Lauge-Hansen.
