Cedell fracture involves which part of the talus?

• A. Lateral tubercle
• B. Talar head
• C. Posteromedial tubercle
• D. Calcaneal facet

Answer: (C)

Cedell fracture is a fracture of the posteromedial tubercle of the talus, a bony prominence on the posterior aspect of the talus where the posterior talofibular ligament attaches. This location is part of the talar posterior process and can be easily missed on standard X-rays, sometimes needing dedicated views or CT to confirm. The other options point to different parts of the talus or its articulation—the lateral tubercle is a different posterior-process fragment, the talar head lies anteriorly, and the calcaneal facet is the inferior articulation with the calcaneus. Thus, the posteromedial tubercle is the correct site for a Cedell fracture.
