NAGASSE, Yoshinobu et al. Retrospective study of cervical arthrodesis with autograft versus hydroxyapatite graft. Coluna/Columna [online]. 2010, vol.9, n.4, pp.440-444. ISSN 1808-1851.

OBJECTIVE: the authors carried out a study to compare the radiografic result in the use of hydroxyapatite graft and iliac crest bone graft (autologous) in the surgical treatment of cervical discal herniation in one level, and a cervical arthrodesis was carried out previously with plate. METHODS: a retrospective study with patients who were submitted to cervical artrodesis, comparing two groups of ten patients: one in which the hydroxyapatite graft was used and the other in which the autologous iliac crestwas used. Postoperative x-rays were measured and compared, in search for losses of angular alignment. RESULTS: the two types of grafts demonstrated an alignment in similar rates, with consolidation in all patients. The study did not show fragmentation of the hydroxyapatite graft or acquittal of the synthesis material. CONCLUSION: in this small series of cases, no significant difference was observed between the results of the anterior cervical arthrodesis with hydroxyapatite graft in relation to the iliac crest bone graft.
