The axial view of the calcaneus (Harris or plantodorsal projection) is obtained with the patient prone and foot dorsiflexed, directing the central X-ray beam about 40° cephalad from the plantar surface through the heel onto the film. It demonstrates the calcaneal tuberosity, body, anterior process and posterior facets, used to assess fractures, subtalar joint alignment and Bohler’s angle.

For a calcaneus X‑ray obtain a lateral and an axial (plantodorsal/Harris) view. Lateral: patient lateral recumbent on affected side, knee flexed, ankle neutral; foot in true lateral, heel centered on cassette; CR perpendicular to heel, directed at the subtalar region (≈1 cm below the medial malleolus). Axial: dorsiflex foot; CR angled 40–45° cephalad through the plantar surface to the posterior calcaneus.

The axis of the calcaneus is an imaginary anteroposterior line along the long axis of the heel bone, running from the posterior calcaneal tuberosity toward the anterior process/calcaneocuboid region. It is used clinically and radiologically to assess hindfoot alignment, subtalar orientation and angular deformities (varus/valgus) and guides surgical planning, orthotic fitting, and gait analysis.

Yes, most calcaneus (heel bone) fractures are visible on plain X‑rays using lateral and axial (Harris) views. However, subtle, non‑displaced or intra‑articular fractures can be missed on radiographs; CT is more sensitive and used for confirmation and surgical planning. If there is severe pain, swelling, deformity, or inability to bear weight, seek urgent evaluation and imaging.

Axial in X‑ray refers to images or views obtained along the body’s longitudinal axis, producing transverse (cross‑sectional) slices. These axial or transverse images are taken perpendicular to the coronal and sagittal planes, showing anatomy as if viewed from head or feet toward the body. Axial views help localize and evaluate lesions, fractures, and internal structures in cross‑section.

Treating a calcaneus fracture begins with immobilization, elevation, ice and analgesia, and strict non‑weight bearing. Obtain X‑rays and CT and refer orthopaedics. Nondisplaced fractures often get casting or splinting with progressive weight‑bearing; displaced or intra‑articular fractures may require open reduction and internal fixation. Monitor for wound complications, start physiotherapy for range of motion and strength when allowed, and consider thromboprophylaxis.
