A retrospective study of operative results after a minimum follow-up period of five years was carried out in a series of 34 patients operated upon for cervical spondylotic myelopathy (CSM). In all the cases, myelography showed involvement of two or more intervertebral spaces. Constitutional spinal cord narrowing was not present, and only one operation was performed in each patient. Of the 34 patients, 16 also had symptoms of cervical spondylotic radiculopathy (CSR). Seventy-four percent of the patients thought that operation resulted in overall improvement of the preoperative clinical picture. This subjective improvement was similar whether the operative procedure consisted of anterior intersomatic fusion or of laminectomy. Amelioration of CSM symptoms occurred in only 8 of the 20 patients subjected to anterior fusion (40%), in contrast to 10 of the 14 patients subjected to laminectomy (71%). In the 16 patients with CSR symptoms associated with CSM, amelioration of CSR symptoms occurred in 6 of the 11 patients subjected to anterior fusion (55%), and in 4 of the 5 patients subjected to laminectomy 80%). It is suggested that laminectomy offers the best results for CSM, associated or not with CSR, when two or more intervertebral spaces are affected.
对34例因脊髓型颈椎病（CSM）接受手术治疗的患者进行了一项回顾性研究，这些患者的最短随访期为5年。在所有病例中，脊髓造影显示两个或更多椎间隙受累。不存在先天性脊髓狭窄，且每位患者仅接受一次手术。34例患者中，16例还伴有神经根型颈椎病（CSR）症状。74%的患者认为手术使术前临床表现总体得到改善。无论手术方式是前路椎间融合术还是椎板切除术，这种主观改善情况相似。接受前路融合术的20例患者中，仅8例（40%）的CSM症状得到改善，相比之下，接受椎板切除术的14例患者中有10例（71%）症状得到改善。在16例伴有CSM的CSR症状患者中，接受前路融合术的11例患者中有6例（55%）的CSR症状得到改善，接受椎板切除术的5例患者中有4例（80%）症状得到改善。研究表明，当两个或更多椎间隙受累时，无论是否伴有CSR，椎板切除术对CSM的治疗效果最佳。
