摘要
目的:探讨腰椎管狭窄症CT影像学分类方法,为手术减压部位及术式选择提供依据.方法:把腰椎管管壁致狭窄病变的组织分为关节突(A)、椎体与椎弓骨性组织(B)、钙化结缔组织(C)、椎间盘(D)、硬膜外瘢痕(E)和黄韧带(F)六个类别,把椎管分为前壁(1)、侧壁(2)、后壁(3)三个区.通过对43例共70个节段腰椎管狭窄症的CT影像学病因诊断,用字母-数字化代码对椎管管壁狭窄因素进行分类,根据不同狭窄因素行个体化治疗.结果:共统计出12类椎管管壁狭窄因素.43例中40例得到定期随访,随访1～5年,优良率90.0%.结论:腰椎管狭窄症管壁狭窄因素分类方法可表达椎管狭窄的性质、部位,有助于术前减压目标的确定、术式选择和电脑信息化处理.
Objective:According to the morphology of the lumbar spinal stenosis showed by CT,a digital classification of the stenotic factors of the lumbar spinal stenosis was considered for the establishment of a concise diagnosis.Method:(1)The classification of the tissues of the spinal canal was designed as follows:A (articular process),B (bony tissue of vertebral body and arch),C(calcified connective tissue),D(disc),E (epidural cicatrix), F(ligamentum flavum).The region of the canal wall:1(the anterior wall),2(the lateral wall),3(the posterior wall).One diagnostic code was composed of a letter and a digit expressing a kind of the stenotic factors of the lumbar spinal stenosis.(2)According to the difference of the stenotic factors of the lumbar spinal stenosis,43 patients were respectively treated with interlaminal fenestration decompression or laminectomy.Result:The rate of the diagnostic coincidence of 43 operating cases was 100%.40 patients were followed up for 1~5 years.The excellent and good rate was 90.0%.Conclusion:This classification of the stenotic factors of the lumbar spinal stenosis is useful for the establishment of an accurate diagnosis,for the concise expression of the lumbar spinal stenosis,as well as for the computerized management.
