摘要:

背景:对于严重的颈椎间盘突出、后纵韧带钙化、黄韧带增生,实施前后联合入路不仅可以达到彻底减压的目的,同时植入cage及前路钢板矫形固定可部分恢复椎体间隙及颈椎生理曲度。
目的:比较颈椎病颈后路单开门椎管扩大成形及增加前路cage融合内固定对治疗后患者颈椎曲度、稳定性及轴性症状发生的影响。
方法:回顾性分析颈椎病外科治疗50例患者的临床资料。其中行一期前后联合入路脊髓减压(前路cage+钢板融合固定)22例(前后路联合治疗组);单纯行颈后路单开门椎管扩大成形(后路开窗铆钉固定)28例(单纯后路治疗组)。治疗后随访6-24个月,分别对两组治疗后神经功能恢复情况、轴性症状的发生率及颈椎曲度指数、病变节段椎间滑移度进行统计分析。
结果与结论:两组患者的神经功能恢复均获得较好的日本骨科学会(JOA)改善率,前后路联合治疗组患者轴性症状的发生率相对低,颈椎曲度指数较单纯后路治疗组患者有较为明显的改善,而单纯后路治疗组椎间滑移度相对较大。结果表明一期前后联合入路使用cage、前路钢板、后路铆钉行脊髓减压可以有效维持颈椎的生理曲度从而维持矢状面的平衡,减少患者轴性症状的发生率,对维持治疗后颈椎长期的稳定性起到重要作用。

Abstract:

BACKGROUND: The combination of anterior and posterior approaches for severe cervical intervertebral disk herniation, posterior longitudinal ligament calcification and ligament flava hyperplasia can completely reduce compression. Simultaneously, cage implantation and anterior plate fixation partially recover vertebral interspace and physiological curvature of cervical vertebra.
OBJECTIVE: To compare the effects of cervical posterior single-door laminoplasty for cervical spondylosis and anterior cage-assisted fusion on curvature, stability and axial symptoms after treatment.
METHODS: Clinical data of 50 patients, who received surgical treatment for cervical spondylosis, were retrospectively analyzed. 22 cases underwent I-stage spinal decompression by the combination of anterior and posterior approaches (anterior fusion cage + steel plate fixation) (combination group). 28 cases underwent cervical posterior single-door laminoplasty (posterior windowing rivet fixation) (posterior approach group). They were followed up for 6 to 24 months. The recovery of neurological function, incidence of axial symptoms, cervical curvature index, and slipping degree of affected intervertebral segments were analyzed statistically.
RESULTS AND CONCLUSION: The neurological functions were greatly improved according to Japanese Orthopaedic Association in both groups. Incidence of axial symptoms was relatively low in the combination group. Cervical curvature index was obviously improved in the combination group compared with the posterior approach group. The slipping degree of affected intervertebral segments was relatively greater in the posterior approach group than that in the combination group. Results suggested that fusion cage, anterior steel plate and posterior 
rivet for spinal decompression in I-stage combination of anterior and posterior approaches can effectively maintain cervical physiological curvature and the balance of sagittal level, reduce incidence of axial symptoms, and play a key effect on keeping posttreatment long-period cervical stability.
