Which of the following describes a Bosworth fracture?

• A. Transverse fracture of the fibula
• B. Comminuted fracture of the sesamoid bones
• C. Bi-mall fracture with posterior displacement of fibular
• D. Fracture involving the interosseous membrane

Answer: (C)

A Bosworth fracture is characterized by a bi-malleolar fracture that includes a specific displacement of the fibula. In this type of injury, the fibula becomes posteriorly displaced, which is significant because it can affect the stability of the ankle joint. This occurs as a consequence of an ankle injury, which often involves an external rotation mechanism, leading to fractures of both the lateral malleolus (fibula) and the medial malleolus (tibia).

The correct choice reflects the unique presentation associated with the Bosworth fracture, highlighting the importance of understanding this particular injury pattern in the context of traumatic ankle injuries. Proper recognition is critical for appropriate treatment planning, which may involve surgical intervention to realign and stabilize the fractured bones. Understanding the mechanics and consequences of this fracture type helps in the management and rehabilitation of patients following such an injury.
