This paper describes the clinical and diagnostic features of 20 cases of scapulohumeral osteoarthritis in Shetland ponies, miniature horses and falabella ponies. The history and clinical signs were similar in all the cases Radiographically they all had consistent changes which consisted predominantly of articular osteophytes and periarticular enthesiophytes. Six of the cases had radiographic evidence of dysplasia of the scapulohumeral joint, although it was uncertain whether this was a primary or a secondary finding. No specific treatment appeared to be advantageous. At follow up, six of the ponies had to be euthanased owing to continuing severe lameness; the other 14 ponies remained lame, but were maintained at pasture by the occasional use of oral non-steroidal anti-inflammatory drugs. No definitive aetiology for the condition was identified, but it is proposed that an underlying dysplasia, or lack of collateral support may predispose the scapulohumeral joint of miniature horse breeds to the disease.
本文描述了设得兰矮种马、小型马和法拉贝拉矮种马20例肩胛肱骨骨关节炎的临床和诊断特征。所有病例的病史和临床症状相似。影像学检查显示，它们都有一致的变化，主要包括关节骨赘和关节周围附着点骨赘。6例病例有肩胛肱骨关节发育异常的影像学证据，不过尚不确定这是原发性还是继发性表现。似乎没有哪种特定治疗方法具有优势。随访时，6匹矮种马因持续严重跛行而不得不实施安乐死；另外14匹矮种马仍有跛行，但偶尔使用口服非甾体抗炎药后可在牧场饲养。该病症的确切病因尚未明确，但有人提出，潜在的发育异常或缺乏侧支支持可能使小型马品种的肩胛肱骨关节易患此病。
