Two sibling male castrated gray wolves (Canis lupus) developed acute onset right forelimb lameness, one at 8 and the other at 11 yr of age. In both cases, the right carpus was swollen, carpal hyperextension was notable, and the wolves exhibited significant intermittent lameness of the affected limb. Radiographs revealed right accessory carpal bone luxation in both cases, with type III fracture of the accessory carpal bone in one wolf. Although carpal bone luxation in domestic dogs is frequently treated surgically, conservative medical management resolved the lameness in both wolves with no further complications.
