TI  - Correlation between cervical spine sagittal alignment and clinical outcome after 
      anterior cervical discectomy and fusion.
PG  - E81-4
AB  - Studies have shown that maintenance of lordosis improves outcomes after anterior 
      cervical discectomy and fusion (ACDF). The relationship between maintenance or 
      restoration of lordosis after ACDF and health-related quality of life (HRQOL) 
      measures has not been evaluated. Preoperative and 2-year postoperative cervical 
      lordosis (C2-C7) and segmental lordosis were measured from upright lateral 
      cervical spine radiographs in patients who had ACDF. Data on the Neck Disability 
      Index (NDI), Short- Form-36 Physical Composite Summary Score, arm, and neck pain 
      scores were also collected. Paired t-tests were used to compare preoperative and 
      2-year postoperative radiographic measures and HRQOL measures. Receiver operating 
      characteristic curves were constructed to identify sagittal parameters that 
      predict achievement of a Minimum Clinically Important Difference (MCID) in 
      outcome measures. One hundred one patients (75 female; mean age, 52 years) were 
      included. There was improvement in all HRQOL measures from preoperative to 2 
      years postoperative. There was no significant difference in preoperative and 
      2-year postoperative sagittal alignment. Receiver operating characteristic curve 
      analysis showed that a postoperative cervical lordosis of at least 6 degrees  predicted 
      achievement of MCID for NDI (8 point change in NDI). This suggests that 
      maintenance or restoration of overall cervical lordosis is important in achieving 
      a successful result after ACDF.
