Rupture of the peroneous tertius was diagnosed in a 7-year-old stallion, based on clinical examinations.
The stifle joint flexed as the limb was advanced forward without flexing the hock. When the limb was pulled
backward, the hock joint extended but the stifle was in the normal position. The recommended treatment
included complete stall rest for 6 weeks followed by limited exercise for 2 months. The animal, ultimately,
returned back to its normal exercise.
