A four year-old intact male Dalmatian was referred to the veterinary teaching hospital at Louisiana State University for acute, non-weight-bearing left hindlimb lameness of three weeks duration. Information supplied by the referring veterinarian indicated the lameness was first diagnosed and treated seven months previously, but recurred three weeks ago. External rotation of the left stifle, mild discomfort upon stifle flexion, mild to moderate muscle atrophy and palpable joint effusion were noted during physical examination. Slight cranial drawer movement with a soft end-point was discovered during manipulation of the left stifle. A triangular bone fragment and thickened, confluent intracapsular soft tissues were observed on radiographs of the stifle. Radiographically, moderate degenerative changes suggested chronicity. This report describes the clinical and radiographic findings of a rarely reported partial avulsion of the origin of the cranial cruciate ligament in a skeletally mature dog.
一只4岁未绝育的雄性斑点狗被转诊至路易斯安那州立大学兽医学院教学医院，其左后肢急性非负重跛行已持续三周。转诊兽医提供的信息表明，该跛行最初于七个月前被诊断并接受治疗，但三周前复发。体格检查发现左膝关节外翻、膝关节屈曲时轻度不适、轻度至中度肌肉萎缩以及可触及的关节积液。在对左膝关节进行手法检查时，发现有轻微的颅侧抽屉运动，终点较软。膝关节X光片显示有一个三角形骨碎片以及增厚、融合的关节囊内软组织。影像学检查显示中度退行性改变，提示病程较长。本报告描述了一只骨骼成熟犬罕见的颅侧十字韧带起点部分撕脱的临床和影像学表现。
