BACKGROUND
Cervical deformity can influence global sagittal balance. We report two cases of severe low back pain and lower extremity radicular pain associated with dropped-head syndrome. Symptoms were relieved by cervical corrective surgery.
CASE PRESENTATION
Two Japanese women with dropped head syndrome complained of severe low back pain and lower extremity radicular pain on walking. Radiographs showed marked cervical spine kyphosis and lumbar spine hyperlordosis. After cervicothoracic posterior corrective fusion was performed, cervical kyphosis was corrected and lumbar lordosis decreased, and low back pain and leg pain were relieved in both patients.
CONCLUSIONS
Cervical deformity can influence global sagittal balance. Marked cervical kyphosis in patients with dropped-head syndrome can induce compensatory thoracolumbar hyperlordosis. Low back symptoms in patients with dropped-head syndrome are attributable to this compensatory lumbar hyperlordosis. Symptoms of lumbar canal stenosis may result from cervical deformity and can be improved with cervical corrective surgery.
背景
颈椎畸形会影响整体矢状面平衡。我们报告两例与低头综合征相关的严重腰痛和下肢神经根性疼痛病例。症状通过颈椎矫正手术得到缓解。
病例报告
两名患有低头综合征的日本女性抱怨行走时严重腰痛和下肢神经根性疼痛。X线片显示颈椎明显后凸和腰椎前凸增加。在进行颈胸段后路矫正融合术后，颈椎后凸得到矫正，腰椎前凸减小，两名患者的腰痛和腿痛均得到缓解。
结论
颈椎畸形会影响整体矢状面平衡。低头综合征患者明显的颈椎后凸可诱发代偿性胸腰段过度前凸。低头综合征患者的腰痛归因于这种代偿性腰椎过度前凸。腰椎管狭窄症状可能由颈椎畸形引起，可通过颈椎矫正手术改善。
