[Treatment strategies for pathological fractures of the spine]

Pathological fractures and instabilities of the spine are most often caused by primary tumors that hematogenously metastasize into the spine. In this context breast, prostate, kidney cell and bronchial carcinomas are the most relevant causative diseases. Furthermore, multiple myeloma is another frequent entity. Primary tumors of the spine are correspondingly rare and only make up a small proportion of all malignant processes in the spine.

The main symptom of pain is prognostically unfavorable in this context and is often associated with progressive instability or pathological fractures. To objectify the treatment approach the neurological status, an oncological assessment, the biomechanical stability and (systemic) general condition (NOMS criteria) of the patient have to be considered. Another major factor is the radiation sensitivity of the tumor. The spinal instability neoplastic (SIN) score is recommended to assess stability. Regardless of whether conservative or surgical treatment is carried out, interdisciplinary cooperation between the specialist departments must be guaranteed in order to achieve adequate treatment for the patient.

If a curative approach is followed an individualized and interdisciplinary surgical strategy must be performed to achieve an R0 resection, usually as a spondylectomy. In the case of palliative treatment, the goal of surgical treatment must be pain reduction, stability and avoidance or restoration of neurological deficits. This requires stabilization in a percutaneous or open technique, possibly in combination with decompression and local tumor debulking.
