|a1=The peroneus tertius has ruptured. The classical signs shown here are extension of the hock with the stifle flexed, and ‘puckering’ of the Achilles tendon (gastrocnemius and superficial digital flexor tendons).

|a4= There is no suitable surgical treatment. Complete box rest for 6–8 weeks, followed by a graduated exercise programme over the next 8–12 weeks, is the treatment of choice. The prognosis is fair to good. <br><br>

Healing is by scar tissue formation between the ruptured tendon ends. Return to a functional unit may not occur, or the peroneus tertius may be injured when the animal returns to work. <br><br>

The location of the injury affects the prognosis. Avulsion of the origin of the peroneus tertius may result in an intra-articular fracture with a hopeless prognosis.
