The authors discuss routine removal of inferior articular processes and their facets during laminectomy, with wide visualization of the lumbar nerve roots, which has proven to be most successful in relief of the symptoms of lumbar spondylosis. No instance of postoperative vertebral instability has been found. In a consecutive series of 70 patients averaging 58.3 years of age, 91% of patients adequately followed did well. Of six patients who did poorly, three had apparent explanations and, presumably, such errors are avoidable. Despite the generally advanced age of this series (12 patients aged over 70 years) there was no mortality or undue morbidity. Patients previously operated on for disc herniation, as a group, were somewhat younger and the spondylosis tended to be more localized (to the area of previous surgery) than in patients operated on for the first time.
作者讨论了在椎板切除术中常规切除下关节突及其关节面，并广泛显露腰神经根，事实证明这在缓解腰椎间盘退变症状方面最为成功。未发现术后椎体不稳定的情况。在连续的70例平均年龄为58.3岁的患者中，91%得到充分随访的患者情况良好。在6例情况不佳的患者中，3例有明显原因，想必此类错误是可以避免的。尽管该系列患者普遍年龄较大（12例年龄超过70岁），但无死亡或过度发病情况。作为一个群体，既往因椎间盘突出接受过手术的患者年龄稍小，且椎间盘退变往往比首次接受手术的患者更局限于（既往手术区域）。
