Cervical myelopathy is often associated with lesions of other levels in the spine such as lumbar canal stenosis and thoracic myelopathy. In case three are difficulties in preoperative diagnosis to determine which level is most involved, postoperative recovery of myelopathy will be poor because of multiple lesions. Seven cases of cervical myelopathy who had such a lesion are presented and the postoperative results are evaluated. Six out of them had lumbar canal stenosis, whereas one had thoracic myelopathy due to OPLL. They all underwent decompressive surgeries of two stages in each level, while they showed no satisfactory results compared with those of cervical myelopathy only.
