Summary

Medical records of 6 Vietnamese pot-bellied pigs with articular fractures of the distal portion of the humerus were reviewed. Evaluation of the medical records did not reveal a sex predilection. All fractures were associated with minor traumatic episodes in young pigs. Of 6 fractures involving the humeral condyle, 4 involved the medial portion, 1 involved the lateral portion, and 1 was a Y-shaped fracture. Five of the pigs underwent surgical repair of the fracture, and all 5 did not have signs of lameness at follow-up evaluations (mean, 11 months). Of 4 pigs that had follow-up radiography, all had evidence of mild to moderate degenerative joint disease. Articular fractures of the distal portion of the humerus should be considered as a differential diagnosis in all Vietnamese pot-bellied pigs with forelimb lameness, even if the trauma sustained appeared mild. Surgical repair in Vietnamese pot-bellied pigs is straightforward, and excellent clinical results can be expected.
