Central and lateral stenoses of the lumbar neural canal are relatively less common causes of chronic pain in the lumbar back and the legs. However, their incidence is much higher than was previously thought. Accurate anatomical diagnosis was difficult until the advent of high resolution computed tomographic scanning. Appropriate decompressive surgery can now be designed and "guided" by the scans and the clinical syndrome. New or highly modified surgical procedures are now being used with good to excellent clinical results in as high as 80% of the cases depending upon the technique chosen. Many of these cases are failed back surgical cases and those whose diagnoses were not established by standard means, e.g., plain films, myelography, low resolution tomography, discography, etc. The good results reported here include patients with pain and disorders of long standing.
腰椎神经管中央和侧方狭窄是引起腰背部和腿部慢性疼痛相对少见的原因。然而，其发病率比以前认为的要高得多。在高分辨率计算机断层扫描出现之前，准确的解剖学诊断很困难。现在可以根据扫描结果和临床综合征设计并“指导”适当的减压手术。根据所选择的技术，新的或经过高度改良的手术方法目前正在使用，高达80%的病例取得了良好至极佳的临床效果。这些病例中有许多是脊柱手术失败的病例，以及那些通过标准方法（如平片、脊髓造影、低分辨率断层扫描、椎间盘造影等）未能确诊的病例。这里报告的良好结果包括患有长期疼痛和病症的患者。
