Sixteen patients 75 years old or older (range, 75-81 years; mean age, 77.5) with cervical myelopathy who underwent surgery were reviewed. There were 12 patients with cervical spondylosis, three with ossification of the longitudinal ligament, and one with disc herniation. Laminoplasty was performed in 12 patients, and anterior decompression with interbody fusion was performed in four.The mean values of the preoperative Japanese Orthopaedic Association score (JOA score), postoperative JOA score, and recovery ratio (RR) were 9.2, 11.8, and 30.2%, respectively. The range of motion in the upper cervical intervertebral regions (C3/4, C4/5) was slightly larger than that in the lower regions (C5/6, C6/7) without significance. On magnetic resonance imaging (MRI), responsible lesions were detected in the upper intervertebral regions (C3/4, C4/5) in most patients. The mean Pavlov's ratio at the responsible lesion level was 0.68. The prevalence of preoperative complications and the incidence of postoperative complications were 87.5% and 43.7%, respectively.In conclusion, cervical myelopathy in elderly patients tended to occur in the upper cervical levels and be associated with the severe disability. Therefore even in patients with mild cervical myelopathy, surgery should be performed if exacerbation is noted. However, preoperative and postoperative complications must be considered.
