The Application Of Peek Cages And Bone Crumbs In-situ In Anterior Cervical Discectomy With Fusion

Objective: To investigate whether PEEK cages and bone crumbs in-situ could substitute for iliac-crest bone in cervical spinal fusion. Methods:We review the 27 patients with cervical spondy myelopathy involving a single level, 13 patients with two,3 patients with three and 1 with four,all of which had been managed with anterior cervical disectomy and fusion and arthrodesis by the bone crumbs in-suit and cages. We also review 23 patients with one level, 15 patients with two as matched group. All cases had been followed-up for an average of 2.25 years. The latest results were analyzed according to JOA score system and recovery rate. The fusion outcome were evaluated by anteroposterior and flexion and extension lateral radiographs of the cervical spine. Results:Compared to the matched group, the follow-up of 44 patients also shown an good and excellent rate of 88.6%. The grafted bone was completely fused with the host vertebrae and the stability of cervical spine was also pretty good. Conclusion: This technique was an idea substitute for iliac-crest bone in cervical spinal fusion. The bone grafting,havesting, decompression and bone grafting in situ could be synchronously performed in one incision. The merits of this technique include shorter operation time, simpler procedure and less trauma and complication to the patient as well as perfect fusion rate and stability of cervical spondylotic.
