Abstract

A 1-year-old 13.5 kg male neutered French bulldog presented for acute left thoracic limb non-weight-bearing lameness following minor trauma. Orthopaedic examination revealed left elbow joint effusion and discomfort on elbow manipulation, particularly in extension. Computed tomography showed separation of the left anconeal process, incomplete fusion of the right anconeal process, and bilateral humeroulnar incongruity. Elbow arthroscopy confirmed complete separation of the left anconeal process. The fragment was removed via caudolateral arthrotomy. Histopathology of the excised fragment demonstrated organized fibrosis and multifocal bone proliferation extending along the separation line, consistent with traumatic separation secondary to an ununited anconeal process. On follow-up examination 4 weeks postoperatively, there was a mild left thoracic limb lameness that had completely resolved by 5-month postoperative. No lameness was reported at long-term follow-up (20 months postoperative).
