[Percutaneous vertebral surgery. Indications, technics and possibilities]

The authors report their own experience with percutaneous vertebroplasty, one of the so called--minimally invasive methods, used to treat a certain group of spinal lesions affecting the vertebral bodies. The paper contains a brief review of the current literature, basic problems, indications and operative technique. The authors remark, that insertion of the needle into the vertebral body gives an access for biopsy before cement injection. This procedure was realised in the case of diagnostic uncertainty. Technical details of transpedicular biopsy are described. The authors present 2 representative cases.
