頸椎変性疾患に対する前方後方併用手術の検討

抄録

  We analyzed the cases combined ventral and dorsal surgery were performed simultaneously for degenerative cervical spine disease. From January 2005 to May 2007, we experienced 206 cases of anterior fusion and 349 cases of laminoplasty. In those cases, 37 operations (7.3%) were performed using the combined approach. They consisted of 23 men and 14 women (mean age 62 years old, range 40-80 years old). All of the cases caused multilevel cervical spondylosis, accompanied with disc herniation in 18 cases, with kyphotic deformity in 10 cases, with spondylolisthesis in 5 cases, with osteophytes in 3 cases and ossification of the posterior longitudinal ligament (OPLL) in 1 case. There were no cases of neurological deterioration and reccurence postoperatively. For the preventation of recurrence in degenerative cervical spine desease, combined ventral and dorsal surgery is a viable option in the treatment of patients with multilevel canal stenosis (more than 3 vertebral levels or more), accompanying with unilaterally deviated disc herniation, osteophytes, and OPLL, with a kyphotic deformity of more than 10° in the neutral position and an angular deformity of more than 15° in flexion position, and with unstable spondylolisthesis.
