摘要

Cespace is a cervical implant designed to obtain intervertebral fusion without bone grafting. The implant is built in titanium and coated with plasmapore (a sort of pure titanium powder). Bone growing through titanium microstructure is induced by the plasmapore, and fusion is progressively obtained once this boneinduction is completed. From January 2002 to December 2008 we operated upon 104 patients employing this implant at one or two cervical spine levels. The more frequent condition was radiculopathy caused by disc herniation or spondilosis (N= 85; 81.7%), followed by mielopathy (N=13; 12,5%). Six cases (5.7%) corresponded to cervical fractures or dislocations. In these latter ones Cespace was implanted as a method of spinal stabilization combined with Caspar plates, avoiding bone grafting. The total number of Cespace implants placed was 120. Clinical results were good in 85,5% of patients. Primary stability was obtained in all cases. Secondary stability (fusion) was evident after 1 to 2 years in all cases, confirming the bone-induction capability of plasmapore without bone grafting. No specific implant complications (pseudoartroses, settling, instability, etc) were registered. We conclude that radical microdiscectomy and Cespace box implant constitutes a good procedure for the treatment of cervical radiculopathy or mielopathy caused by disc herniation or spondylosis, avoiding bone grafting and providing high rates of vertebral fusion. In some cervical fractures associated to instability, Cespace can be used as a reliable substitute of intervertebral bone grafting in combination with anterior plate fixation.
