颈椎管扩大成形术与椎板切除术的疗效比较研究

CANAL—EXPANSIVE LAMINOPLASTY AND LAMINECTOMY IN THE CERVICAL VERTEBRA:A CLINICAL COMPARATIVE STUDY

本研究采用随机对比的方法评价了颈椎管扩大成形术与椎板切除术的疗效。共对48例多节段脊髓型颈椎病、颈椎管狭窄症及颈椎后纵韧带骨化症的患者施行了手术.术后随访结果显示:颈椎管扩大成形术组的平均改善率为70.90±19.94%,而椎板切除术仅为57.59±17.67%;两组间的差异明显(P<0.05)。建议用颈雄管扩大成形术取代常规的于板切除术,以提高手术疗效。

The CUratove effects of Cervical Canal—expamSive laninoplasly andlamineectomy were evaluated in this randomized Comparative study.The operat-ions were performed on forty—eight patients with cervical spondylotie myelopa-thy,s inal Canal Stenosis,or OPLL.The average recovery rate after surggerywas 70.96±19.91% in the grou) of Canal-expansive IaminoplaSty and 57.59±17.69%in the group of laminectomy.There was a significant difference(P〈0.05)betw-een the two groups It is suggested that the ordinary laminectomy should be re-placed by Canal--expanSive laminoplaSty to get better resulst
