La columna torácica es afectada en un 70% de los casos, seguida de la región lumbar y cervical.  Material y métodos:  se presenta el caso de un paciente con diagnóstico de adenocarcinoma mamario derecho, con enfermedad ósea metastásica en región cervical a nivel de C2, C3, inestabilidad del segmento cervical por fractura por compresión del cuerpo C3 de mayor al 80%, sin invasión a canal medular, inicia con parestesias de extremidades torácicas. Se realiza instrumentación 360º en dos tiempos. Posterior al procedimiento la paciente evolucionó sin dolor cervical y tolerando la vía oral.  Discusión:  la enfermedad ósea metastásica genera lesiones importantes en la columna vertebral condicionando inestabilidad; la instrumentación mejora el estado funcional y el pronóstico.]]></p></abstract>

The thoracic spine is involved in 70% of cases, followed by the lumbar and cervical region.  Material and methods:  This is a 59 years old female diagnosed with breast adenocarcinoma and metastatic bone disease in cervical spine C2, C3 level and instability of that segment because of a compression fracture of C3 greater than 80% without invasion of the spinal canal, she begins with paresthesias of upper limbs. A 360º instrumentation was performed in two stages. After the surgical procedure the patient were without neck pain and a good neurological status.  Discussion:  Metastatic bone disease causes significant damage to the spine sometimes create instability proper instrumentation is needed to improve the functional status and prognosis of these lesions.]]></p></abstract>
