VICARIO, C. et al. Anterior cervical fusion with tantalum interbody implants: Clinical and radiological results in a prospective study. Neurocirugía [online]. 2006, vol.17, n.2, pp.132-139. ISSN 1130-1473.

Anterior cervical discectomy and interbody fusion (ACDF) is a widely accepted surgical technique in the treatment of cervical disc disease. Tantalum cages have been recently introduced in spine surgery for interbody fusion because of the advantages of their mechanical properties. We present the results of a prospective clinical and radiological study on 24 consecutive patients who underwent an ACDF with tantalum cages. Clinical evaluation was assessed preoperatively and after surgery by a questionnaire that included a Visual Analogic Scale (VAS) of neck and arm pain, the Oswestry Dissability Index and the Zung Depression Scale. Results were classified by Odom's criteria. Radiological evaluation included flexion-extension X-rays, and changes in distance between spinous processes and Cobb angle were measured. Postoperatively patients were reviewed 3 and 12 months after surgery. A statisitical significative improvement in all clinical data was reported. According to Odom's criteria in 75% of patients the results were considered like excellent or good. Only one case of radiological and clinical pseudoarthrosis was confirmed. No significative differences were reported 3 and 12 months after surgery. Tantalum cages are a very promising and usefull alternative among implants available for ACDF. Compatibility with MRI postoperative studies and the unnecessariness of autograft are some of their advantages.
