title: [Case-clinical studies on three different intervertebral fusion with bone graft and internal fixation in the treatment of cervical spondylotic myelopathy].
abstract: OBJECTIVE
  To evaluate the therapeutic effects of three different intervertebral fusion with bone graft and internal fixation in the treatment of cervical spondylotic myelopathy.
  
  
  METHODS
  In the retrospective study, 83 patients (38 males and 45 females, with an average age of 69 years) with cervical spondylotic myelopathy were divided into three groups. The patients in three groups were treated by autogenous iliac bone grafting (Robingson grafting) with anterior cervical plate-screw fixation, Pyramesh with anterior cervical plate-screw fixation and BAK fixation respectively. JOA scores and the bony fusion time were recorded and the results were evaluated by numeric computer system.
  
  
  RESULTS
  The JOA scores of all the patients were higher than those before surgery (t = 1.55, P < 0.05). There were no statistical difference of JOA scores in the three groups (F = 2.51, P > 0.05).
  
  
  CONCLUSIONS
  It is concluded that internal fixation of the three types is promising to the treatment of cervical spondlotic myelopathy. Robingson grafting with anterior cervical plate-screw fixation provides good stability and bony fusion. BAK is better technically required but there was height loss in clinic. Pyramesh with anterior cervical plate-screw fixation combines the merits of both two techniques above but the cost is higher.
