A calcaneal fracture (fracture of the heel bone) is one of the most disabling foot fractures. The calcaneus is the largest tarsal bone and the primary weight-bearing structure of the hindfoot. It is the insertion point for the Achilles tendon superiorly and the plantar fascia and intrinsic foot muscles inferiorly. Calcaneal fractures are most commonly caused by falls from height (the calcaneus is driven into the talus by the body weight). They are frequently bilateral (both heels) and may be associated with thoracolumbar spine compression fractures (axial loading forces transmit up the skeleton).
Why Calcaneal Fractures Are Particularly Disabling
- The subtalar joint (talocalcaneal joint) is frequently involved in displaced fractures, predisposing to subtalar arthritis
- The Bohler angle (radiographic measure of posterior facet anatomy) drops from the normal 20-40 degrees to less than 0 degrees in severe fractures, indicating significant architectural disruption
- Soft tissue complications (wound dehiscence, compartment syndrome) are common due to the limited soft tissue envelope around the heel
Walking Aid Progression After Calcaneal Fracture
| Phase | Duration | Weight-Bearing Status | Walking Aid |
|---|---|---|---|
| Acute / post-operative | 0-8 weeks | Non-weight-bearing (mandatory) | Frame or crutches; cane is insufficient |
| Progressive weight-bearing | 8-12 weeks | Touch weight-bearing to 50%; CAM boot | Crutches with increasing weight; cane introduced at 10-12 weeks |
| Transition to full weight-bearing | 12-16 weeks | Full weight-bearing in boot then shoe | Single cane contralateral; may be needed 3-6 months |
| Long-term | Post-fracture | Full; monitor for subtalar OA | Cane for subtalar arthritis if develops; often permanent if severe |
Bilateral Calcaneal Fractures and Walking Aid Challenges
Bilateral calcaneal fractures (common in falls from height) present a unique walking aid challenge. Crutches require some lower limb push-off, which may be impossible bilaterally. A wheelchair or knee scooter is often the primary mobility device for 8-12 weeks. Bilateral canes are not appropriate for bilateral calcaneal fractures; bilateral crutches with touch weight-bearing are the minimum, but even these may not be feasible.
Subtalar Arthritis: The Long-Term Cane Scenario
Post-traumatic subtalar arthritis is the most common long-term complication of calcaneal fracture (occurring in up to 30-45% of displaced fractures). Subtalar arthritis causes hindfoot pain with uneven terrain, prolonged walking, and transitions from sit-to-stand. A walking cane for subtalar arthritis follows the same principles as for ankle arthritis: contralateral hand, reduces hindfoot joint loading, most valuable on uneven surfaces and longer distances.
