Overview

The axial calcaneus radiograph images the calcaneal body and subtalar joint to detect fractures and joint involvement. The beam is angled cephalad to project the calcaneus free of superimposition. This view is essential for suspected calcaneal injury after axial load trauma.

Technique

Position the patient supine or prone and angle the tube approximately 40 degrees cephalad to the plantar surface. Center the detector to the calcaneus and include the subtalar joint. Immobilize the foot to reduce motion artifact.

Clinical Indications

Axial calcaneus is indicated for trauma heel pain and suspected intra articular fractures. It complements lateral views for comprehensive assessment. CT is often used for detailed evaluation and surgical planning.

Image Assessment

Evaluate calcaneal height width and posterior facet integrity. Inspect for comminution and subtalar joint involvement. Document fracture pattern and recommend CT for operative planning when indicated.
