To describe a clinical case of Schmorl's node affecting the lumbosacral disc in an Airedale Terrier including surgical management, short-term outcome, and review of the literature.
A five-year-old male Airedale Terrier with signs of chronic spinal pain and right hindlimb muscle fasciculation was diagnosed with a Schmorl's node with computed tomography. Repeat imaging performed two months later identified enlargement of the defect in the seventh lumbar vertebra (L7) and herniation of the lumbosacral disc into the spinal canal.
Dorsal laminectomy and discectomy were performed and the defect was treated with curettage and stabilization of the L7 and first sacral vertebra disc space with pins and bone cement. Immediately postoperatively, the patient had proprioception deficits in the hindlimbs and decreased right patellar reflex. Over the next four months the dog's neurological condition improved and no neurological or gait deficits were present six months postoperatively.
Schmorl's node may be a cause of signs of chronic pain in dogs. Successful management may be achieved surgically, although in the case reported here, recovery was prolonged. To the authors' knowledge, this is the first report of progressive enlargement of a Schmorl's node in a dog.
描述一只艾尔谷梗犬腰荐椎间盘施莫尔氏结节的临床病例，包括手术治疗、短期预后，并对文献进行综述。
一只患有慢性脊柱疼痛和右后肢肌肉抽搐症状的5岁雄性艾尔谷梗犬，经计算机断层扫描诊断为施莫尔氏结节。两个月后进行的重复成像显示第七腰椎（L7）的缺损扩大，腰荐椎间盘疝入椎管。
实施了背侧椎板切除术和椎间盘切除术，并用刮匙处理缺损处，并用钢针和骨水泥对L7和第一骶椎椎间盘间隙进行固定。术后即刻，患犬后肢本体感觉缺失，右膝反射减弱。在接下来的四个月里，犬的神经状况有所改善，术后六个月时未出现神经或步态缺陷。
施莫尔氏结节可能是犬慢性疼痛症状的一个原因。虽然在此病例中恢复时间延长，但手术治疗可能成功。据作者所知，这是犬施莫尔氏结节进行性扩大的首例报告。
