title: Surgical outcomes of elderly patients with cervical spondylotic myelopathy.
abstract: BACKGROUND
  Cervical spondylotic myelopathy is a potentially serious neurologic disorder that commonly presents with gait difficulty and hand dysfunction. Because the development of CSM is in large part related to advanced spondylosis and degenerative disk disease, elderly patients appear to be at an increased risk to develop this condition. The surgical outcomes of this patient population have been understudied; the authors seek to report their clinical results in a series of patients with CSM older than 75 years who underwent surgical treatment.
  
  
  METHODS
  This report is composed of a cohort of 36 elderly patients (older than 75 years) and 34 younger patients (younger than 65 years) who underwent decompressive surgery for CSM at one institution between 2001 and 2005. The patients' functional status was evaluated preoperatively and postoperatively using the mJOA disability scale.
  
  
  RESULTS
  The mean follow-up time in the elderly group was 24 months, with a range from 12 to 48 months. There was a statistically significant improvement between mean preoperative (11.3) and postoperative (14.4) mJOA scores (P< .0001). The younger group had a higher neurologic recovery rate (71%) than the elderly group (59%); however, this was not statistically significant (P= .29). The postoperative complication rate in the elderly population (38%) was higher than in the younger group (6%; P= .002).
  
  
  CONCLUSIONS
  Elderly patients with CSM are likely to obtain neurologic improvement after decompressive surgery. Their postoperative complication rate is higher than that of younger patients, yet most complications appear to be self limiting and do not adversely affect neurologic outcome.
