title: [Comparison between solis fixation fusion and titanium plate fixation by cervical anterior approach].
abstract: OBJECTIVE
  To investigate the effect difference between the Solis fixation fusion and the titanium plate fixation by the cervical anterior approach after decompression and bone graft implantation.
  
  
  METHODS
  Of the 104 patients with cervical disease from September 2001 to March 2004, 36 were treated with the Solis implantation after decompression by the cervical anterior approach, and 68 were treated with the titanium plate fixation after decompression and bone graft implantation. The recovery of the neurological function in all the patients were assessed with the JOA Scoring at 6 weeks, 3, 6, 12, 24 and 36 months. The fragment fusion and its stability as well as the changes in the intervertebral height were assessed with X-ray examination.
  
  
  RESULTS
  According to the JOA Scoring, the excellent and good outcomes accounted for 94.4% in the Solis group and 94.1% in the titanium plate group. In all the patients, the fragment fusion was achieved in 3 months. The change in the Cobb angle of the fused fragment was less than 5 degrees at the flexion-extension posture, 3.6 +/- 0.8 degrees in the Solis group, 2.4 +/- 0.7 degrees in the titanium plate group. There was significant differences between the two groups (P < 0.05). The intervertebral height of the operation fragment in the Solis group increased 1.6 +/- 0.7 mm, which was higher than that in the titanium plate group (P < 0.05).
  
  
  CONCLUSIONS
  Clinical effects of the two internal fixation operations are good; however, the Solis fixation has more advantages because of its simpler performance, less trauma, and fewer complications.
