The subtalar joint (talocalcaneal joint) is vital for hindfoot stability and mobility.
- Posterior facet: largest, best seen on lateral radiographs and CT
- Middle facet: on the sustentaculum tali, may communicate with the talonavicular joint
- Anterior facet: smallest, may merge with the middle facet
Imaging pearls:
- Sustentaculum tali appears brick-shaped on lateral X-ray
- Anterior calcaneal process should not articulate with the navicular—if it does, think coalition
- Harris view: posterior and middle facets normally parallel (<20°)
- CT/MRI: gold standard for coalitions and subtle variants
