M\u00c9TODO: An\u00e1lise retrospectiva dos prontu\u00e1rios dos pacientes tratado de 2002 a 2010 no IOT-HCFMUSP. Crit\u00e9rio de inclus\u00e3o: fratura da pars interarticularis de C2. RESULTADOS: 68% dos pacientes do sexo masculino com idade m\u00e9dia de 39,1 anos. Utilizamos a classifica\u00e7\u00e3o de Effendi, modificada por Levine-Edwards. Observamos fratura do tipo I em cinco pacientes (31,2%) e tipo II em oito pacientes (50%). Apenas tr\u00eas pacientes (18%) apresentaram fratura do tipo IIa. N\u00e3o houve casos do tipo III. Mecanismo: Oito acidentes automobil\u00edsticos e quatro quedas. Outros mecanismos: atropelamento e mergulho. Tratamento: tra\u00e7\u00e3o com halo craniano em onze pacientes. Foram usados gesso minerva e halo-gesso. Tempo de consolida\u00e7\u00e3o: 3,6 meses. Tempo de seguimento: 9,6 meses. DISCUSS\u00c3O: Nossos resultados confirmam que fratura do enforcado apresenta bom progn\u00f3stico. N\u00e3o houve necessidade de cirurgia em nenhum caso. A incid\u00eancia de d\u00e9ficit neurol\u00f3gico \u00e9 baixa. Nenhum paciente apresentou fratura inst\u00e1vel, tipo III. CONCLUS\u00c3O: Este trabalho sugere que a espondilolistese traum\u00e1tica do \u00e1xis continua sendo uma les\u00e3o satisfatoriamente tratada de forma conservadora na maioria dos casos.
