Plain-English summary

Two Miniature ponies were brought in for severe shoulder pain. One pony refused to lift either front leg and walked in a strange way, while the other had sudden lameness in one front leg and wouldn't put weight on it. Despite trying pain relief, neither pony improved, and sadly, both were euthanized due to the severity of their condition, which was linked to shoulder joint disease. A fracture was found in one pony's shoulder joint during examination.

Abstract

Two cases of severe scapulohumeral osteoarthritis in Miniature ponies are described, one bilateral and the other unilateral. The condition is thought to occur in miniature breeds as a result of scapulohumeral dysplasia. The presentation in one of the ponies was unusal: it refused to pick up either fore limb, with progression to a uniquely bizarre gait with narrow forelimb placement, an arched back and widely placed hindlimbs camped well forward under the body. The other pony was presented for an acute unilateral non-weight bearing forelimb lameness. Response to analgesia in both cases was poor and both ponies were euthanased. A pathological fracture was evident in one affected glenoid cavity.
