An avulsion fracture of the calcaneal tuberosity: delay of treatment causes the ‘Achilles heel’ of optimal recovery

A 72-year-old woman was diagnosed with an avulsion fracture of the tuberosity of the calcaneus. The fracture was planned for elective fixation 12 days after the accident. The planned open reduction and internal fixation was not possible due to a decubital wound on the Achilles heel as a result of pressure on the skin of the fractured tuberosity. Closed reduction and internal fixation was performed, leading to an acceptable outcome. Avulsion fractures of the tuberosity of the calcaneus are rare injuries, and delay in treatment should be avoided as it may lead to preventable complications.
