Zusammenfassung: | OBJECTIVE: To report the difficulties in managing a case of os odontoideum. METHODS: Female patient, 12 years old who developed a quadiparesis after minor cervical trauma in October 2005. In the emergency department a congenital cervical anomaly was identified. The patient was placed in a Stryker® frame and, few days later, in a halo bracing. After 3 months, an infection around the pins emerged and the halo vest had to be removed. A severe C1-2 instability persisted and a C1-C2 Gallie procedure was attempted. In the following weeks the bone disappeared and another procedure was attempted in June 2006 - C1 laminectomy and occiput-C3 fusion. In the following months the neurological status of the patient improved and a complete mass of occiput-C3 fusion was observed. RESULTS: We choose a posterior cervical arthrodesis of C1-C2 using the Gallie technique. Since the condition was not resolved we performed a second surgery, C1 laminectomy (determined by SAC of 8, 3 mm in MRI) followed by posterior occiput-C3 fusion. In our case, until now, there is no evidence of axial decompensation, but a more prolonged follow-up is needed. CONCLUSIONS: The treatment of os odontoideum has many considerations but the essential that in the presence of instability and neurological deficit a solid fusion is achieved. In case of failure of posterior atlantoaxial wiring, the occiput-C2 or C3 fusion with rods seems to be an excellent option with a high rate of success, avoiding the need for additional support.
OBJETIVO: Informe sobre las dificultades para tratar un caso de os odontoideum. MÉTODOS: Paciente, una adolescente, de 12 años de edad, que desarrolló una cuadriparesia después de un traumatismo cervical leve en octubre de 2005. En el Departamento de Primeros Auxilios, se identificó una anomalía cervical congénita. La paciente fue colocada en un marco de Stryker®, unos días después, en un braguero de halo. Cuando transcurrieron 3 meses, surgió una infección alrededor de los pernos y se tuvo que retirar el chaleco de halo. Persistió una grave inestabilidad C1-2 y se intentó un procedimiento de Gallie C1-C2. En las semanas siguientes, el alambre desapareció y, en junio de 2006, se intentó otro procedimiento - laminectomía C1 y fusión de occipucio-C3. En los meses siguientes, el estado neurológico de la paciente mejoró y se observó una masa completa de fusión occipucio-C3. RESULTADOS: Elegimos una artrodesis cervical posterior de C1-C2 usando la técnica de Gallie. Como la condició |
