Which structure attaches to the lateral process of the talus?

• A. Groove for flexor hallucis longus
• B. Ankle mortise joint
• C. Talar head articulation
• D. Facet for calcaneus

Answer: (A)

The lateral process of the talus has a posterior groove that serves as the path for the tendon of the flexor hallucis longus. This groove sits on the talus’s posterior surface and lies near the lateral aspect, guiding the tendon as it travels from the leg to the sole. The ankle mortise refers to the synovial joint formed by the tibia, fibula, and talus, not a structure that attaches to the lateral process. The talar head articulates with the navicular bone, which is a different facet altogether. The facet for the calcaneus is the articular surface with the calcaneus on the inferior side. Therefore, the groove for the flexor hallucis longus best matches the structure associated with the lateral process.
