Both calcaneal and central tarsal bone fractures are commonly encountered in the racing greyhound. While isolated fractures of the numbered tarsal bones are uncommon, malleolar fractures are encountered frequently in small animal practice. Fractures of the central tarsal bone or calcaneal fractures in both dogs and cats may be either fatigue or stress fractures, or associated with Knees and Teeth Syndrome, which may alter the typically expected presentation and prompt assessment for additional fractures, both in the tarsus and elsewhere. Surgical stabilisation is often the treatment of choice, particularly for fractures with an articular component. In many cases, surgical stabilisation leads to a positive outcome, with Greyhounds often being able to return to racing. However, it is important to be aware that fractures in non-racing dogs tend to be more complex and that this good prognosis may not be appropriate to extrapolate. Depending on the nature and severity of injuries, joint preservation may not always be a realistic goal. If the joint cannot be preserved, arthrodesis may become necessary.
