[Anterior cervical diskectomy and fusion with allograft and internal fixation].
OBJECTIVE
To evaluate the effect of cylindrical titanium mesh packing cancellous allograft in the anterior cervical fusion for the cervical spondylosis with anterior titanium plate.


METHODS
Ninety-eight patients with cervical spondylosis underwent diskectomy and cancellous allograft contained in cylindrical titanium mesh enhanced by anterior titanium plate system. Sixty-four patients were followed up clinically and radiographically. The mean follow-up time was (15.2 +/- 1.7) months. JOA scores and Nurick myelopathy grading system were used for clinical assessment. Roentgenograms were analyzed to identify the stability of fused levels.


RESULTS
In all patients of 98 cases, the wounds were normally healed without acute or chronic infection. In statistical analysis of 64 patients followed up, the mean JOA scores was (11.6 +/- 1.8) preoperatively and improved to (16.0 +/- 1.2) at final follow-up (P < 0.05). And the mean Nurick grades were (2.7 +/- 0.7) and (0.7 +/- 0.8) before and after surgery respectively (P < 0.05). The X-ray films demonstrated that no meshes were found displacing or subsiding. New bone formation occurred in the back of meshes at 5 months after surgery. The final follow-up fusion rate was 95%.


CONCLUSIONS
The cancellous allograft impacted into titanium meshes for cervical fusion has gained excellent or good results clinically and radiographically in short term follow-up.
