» Dropped head syndrome is a group of disorders with diverse etiologies involving different anatomical components of the neck, ultimately resulting in a debilitating, flexible, anterior curvature of the cervical spine. » Causes of dropped head syndrome include myasthenia gravis, amyotrophic lateral sclerosis, Parkinson disease, radiation therapy, and cumulative age-related changes. Idiopathic cases have also been reported. » Nonoperative treatment of dropped head syndrome includes orthotic bracing and physical therapy. » Surgical treatment of dropped head syndrome consists of cervical spine fusion to correct the deformity. » The limited data available examining the clinical and radiographic outcomes of surgical intervention indicate a higher rate of complications with the majority having favorable outcomes in the long term.
“垂头综合征”是一组病因不同的疾病，涉及颈部不同解剖部位，最终导致颈椎无力、灵活、前凸。“垂头综合征”的病因包括重症肌无力、肌萎缩侧索硬化、帕金森病、放射治疗和与年龄相关的累积性变化。也有报道称其为特发性疾病。“垂头综合征”的非手术治疗包括矫形支具和物理治疗。“垂头综合征”的手术治疗包括颈椎融合术以矫正畸形。现有关于手术干预的临床和影像学结果的有限数据表明，并发症发生率较高，但大多数患者的长期预后良好。
