title: Suspected primary scapulohumeral osteoarthritis in two Miniature ponies.
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.
