During the operation, the sampling work “canal” is introduced into the vertebra through a small (3-5 mm) incision. To introduce the work “canal”, the surgeon inserts a piercing device called needle into the vertebra with image intensification (X-ray) targeting, and then removes a staple wire that ends in the vertebral body by removing its inner conductive stem. The surgeon then pulls off the sleeve of the piercing device called the needle from the staple wire, and then pulls the work “canal” onto the wire. The work “canal” is essentially a tube with a thicker pen diameter. The sample is taken through the tube.
Following histological sampling, the weakened vertebral body can be filled with “bone cement” as needed to stabilize the structure. Filling with “bone cement,” or vertebroplasty, may be necessary to prevent the weakened structure of the vertebra from collapsing, which can occur under much less strain than in the case of a healthy vertebra.
If filling is carried out as well with “bone cement”, the material called Polymethylmethacrylate (PMMA) used as bone cement is loaded through the same work “canal” through which the sampling took place. PMMA does not decompose, does not rebuild, only fills gaps.
