摘要
目的 :探索一种颈椎管成形同时扩大神经根管的术式。方法 :78例颈椎管狭窄症患者 ,按施术方式不同分成两组 ,双开门成形并神经根管扩大术者 4 2例为 A组 ,施术方法为 :用微气钻在关节突内 1/ 3处向前外斜挖骨槽 ,折断椎弓双开门成形后 ,神经根管后壁后移 ,从而扩大神经根管 ;单纯椎板双开门成形术 3 6例为 B组 ,对比观察两组疗效。结果 :78例获 18个月～ 4年 10个月 ,平均 2年 4个月的随访 ,优良率分别为 :A组 88.1% ,B组 63 .9%。统计学处理 :0 .0 5 >P>0 .0 1,差异有显著性。结论 :双开门椎管成形并神经根管扩大术式 ,减压有效 ,克服了单纯椎板成形术后脊髓、神经根后移 。
Objective:To probe into a new kind of operation on cervical vetebra canaloplasty and the enlargtment of intervertebra foramenotomy Methods:78 cases of patients with stricture of cervical vertebra canal were devided into two groups.The patients in Group A(42 cases)were operated by double opening doors plasty and the enlargement of the canal of the nervous roots,and ditched obliquely at about one-third of the internal side of the articular process by pheumatic drill After doule opening doors,the vertebra arch was broken off and the backwall of the canal was formed,so that the nervovs root was enlarged.36 cases in Group B were simply perfommed double opening doors.ResultsL:78 cases of the patients were followed up for 18 months to 4 years and 10 months,the excellent rate in Group A was 88.1% while that in Group B 63.9%(0.05>P>0.01).Conclusion:The operation mentioned above is simple and effective to expend the canal of the nervous root.
