Outcome from surgery for cervical spondylosis is often disappointing. To identify possible causes of poor outcome 56 such patients referred for post-operative computed myelography or MRI were evaluated, 22 of which eventually had further surgery. Alternative diagnoses to cervical spondylosis were eventually established in 14.3%; 26.8% had spinal cord atrophy 15.6% of which also had myelomalacia; 28.6% had diffuse spinal canal stenosis; and in 57.1% surgery had failed to decompress the spinal canal. These findings can be partly explained by patient selection criteria; nevertheless they do serve to emphasises the point often ignored in discussions of the efficacy of surgery in cervical spondylosis, that operations significantly often fail to achieve adequate decompression. Furthermore there was no evidence in this material that osteophytes regress after spinal fusion.
颈椎病手术的结果往往令人失望。为了确定预后不良的可能原因，对56例因术后脊髓造影或磁共振成像（MRI）而转诊的此类患者进行了评估，其中22例最终接受了进一步手术。最终，14.3%的患者被确诊为除颈椎病之外的其他疾病；26.8%的患者存在脊髓萎缩，其中15.6%还伴有脊髓软化；28.6%的患者存在弥漫性椎管狭窄；57.1%的患者手术未能实现椎管减压。这些发现部分可以通过患者选择标准来解释；然而，它们确实有助于强调在讨论颈椎病手术疗效时经常被忽视的一点，即手术常常无法实现充分减压。此外，该资料中没有证据表明椎体骨赘在脊柱融合术后会消退。
