中文摘要 | 齒狀突異常分為5種類型:Os odontoideum、ossiculum terminate、齒狀突發育 不全、齒狀突底未發育與齒狀突未發育。此5種齒狀突異常皆可導致寰椎與樞椎關節的不穩 定,且其臨床的徵象、症狀和治療方法皆相同,唯有放射線檢查才有獨特的特徵加以區分。 其發生率至今未明。本文報告1位15歲男孩由於右側肢體逐漸麻木1個月而住院。經由頭 部放射線攝影與核磁共振檢查證實為 os odontoideum。 病灶以自體髂骨融合術和 Halifax 椎板間夾固定術加以治療。此寰椎與樞椎的後固定手術證實是成功的治療方法。本文將進一 步討論齒狀突異常的臨床變異性、病因學、診斷和外科的處理方法。 |
英文摘要 | There are five types of odontoid anomalies: os odontoideum, ossiculum terminale, hypoplasia of the odontoid, aplasia of the odontoid base and aplasia of the odontoid. All five anomalies may lead to atlantoaxial instability. Their clinical signs, symptoms and treatments are identical. Only radiographic findings are distinctive. The incidence of odontoid anomalies is uncertain. A 15-year-old boy was hospitalized with progressive numbness of his limbs on the right side for one month. Os odontoideum was confirmed by cervical radiography and magnetic resonance imaging. The lesion was stabilized with autogenous iliac bone fusion and Halifax interlaminar clamp fixation. Treatment with posterior fusion of the C1-C2 vertebrae proved successful. The clinical variations, etiology, diagnosis and surgical management of odontoid anomalies are discussed. |
