Once the needle passes the pedicle into the vertebral body, the needle tip can be advanced to the junction between anterior and middle third of the vertebral body. Then the second needle is placed into the contralateral half of the vertebra body in a similar fashion.
We use Codman cranioplastic (30g), sterile barium sulfate powder (12g), and tobramycin (1.2g).
First powder polymethylmethacrylate is mixed with barium sulfate and tobramycin in a sterile plastic bowl. Then liquid polymethylmeth-acrylate is added to the powder and admixtured by a tongue blade to a dough-like consistency. The cement is then poured into a 10 ml syringe, and divided into multiple one-milliliter Luer-Lock syringes.
We use 1 ml syringes attached directly to the bone biopsy needle to inject the cement. Fluoroscopic control is important for early detection of leakage.
