Abstract：Objective To compare the Zero-p and conventional titanium plate internal fixation system in the short-term and medium-term curative effect. Methods The clinical data of 48 patients with cervical intervertebral disc herniation who underwent anterior cervical discectomy and fusion(ACDF)by Zero-p implant(n = 23)or traditional titanium plate with cage (n = 25)between June 2009 and July 2009 were retrospectively analyzed. The Bazaz dysphagia grading、the Neck Disability Index(NDI)、Japanese Orthopaedic Association(JOA)scoring、ameliorative rate of symptom in both groups were measured and compared. The radiographs of the cervical spine were made to assess bone graft fusion and internal fixation complications、adjacent-level ossification development. Results The incidence and severity of postoperatie dysphagia of Zero-p group were lower than the titanium plate group. Postoperative symptoms,JOA score,NDI scores of 1 year follow-up were improved signifi-cantly. At the medium-term evaluation of curative effect,the Zero-p was better than the conventional titanium plate internal fix-ation at improving symptoms,improving quality of life,reducing adjacent segmental heterotopic ossification occurred on compet-itive advantage. Conclusion Zero-p can effectively reduce the difficulty of swallow,compared with the conventional titanium plate internal fixation. The short-term curative effect of two groups is similar. At the medium-term evaluation of curative effect, the Zero-p is superior to the conventional titanium plate internal fixation.
