The percutaneous cavity coblation method for the treatment of tumours and metastases in the spine represents a sure, minimally invasive procedure for patients as demonstrated by short-term and long-term results. Due to the percutaneous, minimally invasive access, the OP risks, especially blood loss and OP times are clearly low and shorter. This new method is as yet only available in a few medical centres in Germany as well as in other countries but at the moment it is being used successfully and from our point of view has a promising future.

Tumours and metastases of the spine are extremely stressful for patients, especially for elderly multimorbid patients. The modern cavity/coblation method offers a very good therapeutic alternative for such patients. The goal of this article was to evaluate and present the characteristics, significance, opportunities, issues of the minimum invasive cavity/coblation method as well as the results of the treatment of 302 patients with vertebral tumours and metastases.

The cavity/coblation method has been demonstrated to be a safe, minimally invasive procedure, with good short- and long-term results and lower complication rates. A comprehensive diagnostic, including tumour staging, the correct indication, and prognosis estimation, is important.
