title: Effectiveness of the laminoplasty in the elderly patients with cervical spondylotic myelopathy.
abstract: OBJECTIVE
  The purpose of this study is to evaluate clinical and radiological outcomes analysis of the laminoplasty in the elderly patients, and to compare with the non-elderly patients.
  
  
  METHODS
  A retrospective study of the short term result in patients who had treated with the laminoplasty for cervical spondylotic myelopathy (CSM) was performed. From January 2008 to December 2012, total 62 patients were operated with single open-door technique because of CSM; 28 patients were the elderly and 34 patients were the non-elderly. We evaluated some factors including sex, symptom duration, estimated blood loss during operation, operation time, hospitalization day, complications, pre- and postoperative modified Japanese Orthopedic Association (mJOA) score, recovery rate of mJOA score, achieved mJOA score, mean cervical canal width and expansion ratio of antero-posterior diameter in order to identify difference between the two group. Clinical outcomes were calculated with the recovery rate of mJOA score at the time of one year after operation.
  
  
  RESULTS
  Mean age were 71.9 in the elderly group and 52.9 in the non-elderly group. Although postoperative mJOA score in the elderly group was lower than that of the non-elderly group, achieved mJOA score was statistically same between the two groups. Other clinical and radiological outcomes were also statistically same.
  
  
  CONCLUSIONS
  We conclude that the laminoplasty also assures good clinical outcomes in the elderly patients with CSM, same as in the non-elderly group.
