It is considered a late complication of lumbar spine arthrodesis. It has been very important due to the procedures in the last years. Objective: To evaluate the risk factors associated with the disease at adjacent level as well as its relationship with the natural history of degenerative disease of the lumbar spine. Material and Methods: This was a retrospective study, from January 2000 to December 2002.Thirty-eight patients undergoing arthrodesis in the lumbosacral spine using the pedicle screw fixation participated in the study. Results: These patients had a mean follow-up of 30 months; 10 patients presented adjacent segment disease, 7 disc degeneration, 2 spinal stenosis and one discal spine hernia. The patients´ mean age was 48.5 years; female sex was the majority. Degeneration occurred in 4 patients with stenosis; 4 with spondylolisthesis, and 1 with post disc hernia; all these had been submitted to arthrodesis of lumbosacral spine. The majority was asymptomatic, after being treated by arthrodesis in multiple levels. There was no statistical difference when the above factors were related. Conclusion: Adjacent segment disease is a late complication in the arthrodesis of lumbosacral spine with no relationship of risk factors presented in this study. Therefore, its origin could be related with the natural history of the degenerative disease of lumbar spine. / A doença do nível adjacente é definida como um processo anormal que se desenvolve no nível adjacente, acima e/ou abaixo do segmento artrodesado. Considerada como uma complicação tardia da artrodese da coluna vertebral, tem-se tornado muito importante em decorrência do aumento dos procedimentos nos últimos anos. Objetivo: Avaliar os fatores de risco associados à ocorrência da doença do nível adjacente e sua relação com a história natural da doença degenerativa da coluna vertebral. Material e métodos: Análise retrospectiva de janeiro de 2000 a dezembro de 2002, realizada em 38 pacientes submetidos a artrodese de coluna lombosacra com a utilização de parafuso pedicular. Resultado: Os pacientes analisados apresentavam follow up médio de 30 meses, com a presença de 10 pacientes com doença do nível adjacente; sendo 7 com degeneração discal, 2 com estenose de canal vertebral e 1 com hérnia de disco. A idade média dos pacientes foi 48,5 anos, com predomínio no sexo feminino. A degeneração ocorreu em 4 pacientes com estenose de canal, em 4 pacientes com espondilolistese, em 1 paciente com escoliose e em 1 paciente pós hérnia de disco, os quais tinham sido submetidos a artrodese da coluna lombosacra. A maioria dos pacientes foram submetidos a artrodese em múltiplos níveis e apresentavam-se assintomáticos. Nenhuma diferença estatística foi evidenciada quando relacionados os fatores acima. Conclusão: A doença do nível adjacente é uma complicação tardia existente na artrodese de coluna lombosacra, não relacionada aos fatores de risco apresentados; portanto o seu aparecimento estaria relacionado à história natural da doença degenerativa da coluna lombar.
