What symptom is associated with talocalcaneal coalition?

• A. Pain in the heel
• B. Pain over the sinus tarsi
• C. Swelling of the ankle
• D. Numbness in the toes

Answer: (B)

The symptom associated with talocalcaneal coalition is pain over the sinus tarsi. This condition involves the fusion of the talus and calcaneus bones, which can restrict motion and lead to abnormal pressure and stress on the structures around the subtalar joint. The sinus tarsi, located on the lateral side of the foot, is an important anatomical region that encompasses various ligaments, tendons, and the peroneal tendons. When a coalition exists, the inflammation and mechanical stress can manifest as localized pain in this region, making it a distinctive characteristic of talocalcaneal coalition. This pain may be exacerbated by activity or certain positions that involve subtalar motion. Other symptoms such as heel pain or swelling of the ankle may occur but are not specific to this coalition, and numbness in the toes typically relates to neural issues rather than a structural bone coalition. Thus, the nuanced presentation of pain over the sinus tarsi is a key descriptor that aligns specifically with talocalcaneal coalition.
