Double Cervical Bird Beak Sign Resulting in Dysphagia

Objective: The authors report a rare case of ossification of the anterior longitudinal ligament in the cervical spine underlying dysphagia. Case Report: We report the case of a 50-year-old male presenting with difficulty swallowing and choking. CT of the cervical spine demonstrated anterior longitudinal ligament hypertrophy with osteophytes worst at C1-C2 and C6-C7, without spinal cord compression. A videofluoroscopic swallow study revealed reduced epiglottic inversion and hyolaryngeal elevation resulting in incomplete clearance from the pharynx, as well as compression of the esophagus. Subsequently, the patient underwent osteophytectomy. There were no intraoperative or postoperative complications. Two weeks after the surgery, videofluoroscopic swallow demonstrated improved function and reduced compression. Four weeks postoperatively, the patient completely regained swallowing function without pain.

胸椎黄韧带骨化症的诊断与治疗

本文报告１１例胸椎黄韧带骨化症的临床资料，其中５例是氟骨症患者，临床表现及影象学检查均较为严重，且手术治疗效果差，胸椎黄韧带骨化症常表现为较典型的胸椎管狭窄症状，早期症状主要表现为下肢麻木、无力，好发部位为Ｔ９～Ｔ１２，ＣＴ及ＭＲＩ是理想有效的检查手段，治疗目前以后路全椎板切除减压为主。

对颈椎间盘突出症的再认识

报告经ＣＴ、ＭＲＩ及手术证实的颈椎间盘突出症２７例，着重讨论了颈椎间盘突出症与颈椎病的关系，认为颈椎间盘退变是两者的共同病理基础。颈椎间盘突出不仅是单纯的髓核突出，晚期还可伴有骨赘增生、椎管狭窄、ＯＰＬＬ等改变。作者认为，凡是与颈椎间盘突出有关的颈椎病变都应归入颈椎间盘突出症的范畴。
