Talocalcaneal luxation with plantar displacement of the head of the talus in a dog and a cat

A dog and a cat suffered talocalcaneal luxation with plantar displacement o f the head of the talus. Each case was associated with luxation of the talo central joint and subluxation of the calcaneoquartal joint. The collateral ligaments were not significantly disrupted and this made it technically dif ficult to reduce the luxations. However, after open reduction, the luxation s were inherently stable and a positional screw provided long-term stabilit y. Both animals returned to their previous level of activity with no detect able signs of lameness.
