Anterior cervical diskectomy and fusion with allograft and internal fixation / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of cylindrical titanium mesh packing cancellous allograft in the anterior cervical fusion for the cervical spondylosis with anterior titanium plate.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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%.</p><p><b>CONCLUSION</b>The cancellous allograft impacted into titanium meshes for cervical fusion has gained excellent or good results clinically and radiographically in short term follow-up.</p>
