Clinical Scenario
A 38-year-old roofer presents after falling 3 metres from scaffolding, landing on his feet. He has severe bilateral heel pain and swelling and is unable to weight bear. He also reports low back pain. Examination reveals bilateral heel ecchymosis extending to the plantar arch (Mondor's sign), tense swelling, and tenderness over the calcanei. The right heel has posterior skin tenting with blanching.
Lateral radiograph showing calcaneal fracture with decreased Bohler's angle (<10°) and loss of calcaneal height. CT coronal images demonstrate Sanders Type III fracture with 3 fragments of the posterior facet. Note widening of the calcaneal body and lateral wall blowout.

Exam Day Cheat Sheet
Must Mention
- •10-15% spine fracture association - CHECK SPINE
- •Sanders classification (coronal CT, posterior facet fragments)
- •Bohler's angle: normal 20-40°, <20° = significant
- •Wrinkle test before ORIF (7-14 days)
- •Skin tenting = URGENT reduction
- •UK Heel Fracture Trial: no difference at 2 years
Common Pitfalls
- •Not checking spine (10-15% association)
- •ORIF before soft tissue recovery (wound complications)
- •Missing skin tenting as urgent
- •Operating on Sanders IV (consider primary fusion)
- •Missing foot compartment syndrome
- •Not discussing UK Heel Fracture Trial in counselling
