title: [Association between cervical curvature and cervical sympathetic symptoms].
abstract: OBJECTIVE
  To investigate the association between cervical curvature and cervical sympathetic symptoms.
  
  
  METHODS
  The clinical data of 318 patients with cervical spondylosis who underwent surgical treatment in our department between July 2003 and December 2007 were retrospectively analyzed. All patients were divided into group without sympathetic symptoms (n = 284) and group with sympathetic symptoms (n = 34) . The curvatures of both groups on cervical lateral radiographs were measured using Borden method and statistical analysis was performed.
  
  
  RESULTS
  The incidence of abnormal cervical curvature in group with cervical sympathetic symptoms were 67.6% (23/34), which was significantly higher than that in group without cervical sympathetic symptoms (50.7%, 144/284) (P < 0.05).
  
  
  CONCLUSIONS
  Cervical curvature abnormality may be an independent factor that affects the cervical sympathetic symptoms.
