title: [360 degrees instrumentation for cervical instability due to metastatic bone disease. Case report].
abstract: The spine is the most common site for bone metastases; being the breast, prostate and lung cancer which have most affected. The thoracic spine is involved in 70% of cases, followed by the lumbar and cervical region.
  
  
  
  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.
  
  
  
  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.
