颈椎间管切开减压治疗神经根型颈椎病27例

Treatment of cervical spondylosis of the nerve root type with facetectomy

采用颈椎间管切开减压治疗症状严重的神经根型颈椎病２７例３２侧。随访１０个月～３．３ａ，按Ｏｄｏｍ标准评定疗效。结果：优１５例，良９例，改进３例，优良率８９％。提示：非手术疗法久治无效，后外侧型颈椎间盘脱出有明显单根神经根功能障碍者，适合于颈椎间管切开减压术；手术减压范围以切除关节突内侧５～６ｍｍ的椎板，暴露神经根长度６～７ｍｍ为宜。

cases(32 sides)of cervical spondylosis of the nerve root type were treated with facetectomy.The follow-up of 10 months to 3. 3 years showed satisfactory results according to the criterion of Odom.The results indicated that there were 15 excellent cases,9 good,and 3 improved.The rate of superiority was 89%.It is concluded that fecetectomy was preferable to the cases of cervical disc herniation of the posterolateral type with obvious defunction of the single nerve root and failing in non-operative treatment for cervical spondylosis of the never root type.The resection of 5～6mm from the inside to the outside and exposed 6～7 mm nerve root was the best range.By reaching this range,the nerve root can be decompressed completely and the stability of the cervical vertebra can be maintained to the most extent.
