VERTEBRAL BIOPSY
Percutaneous vertebral biopsy is a safe and effective technique for the evaluation of spinal lesions. It can be performed during a Kyphoplasty or Vertebroplasty procedure with a single transpedicular passage using the coaxial technique, with little patient discomfort and improved safety.
VERTEBROSTEEL™, VERTEBROPLASTIC™, RENOVA SPINE™ 11G and RENOVA SPINE™ 8G kyphoplasty systems can be used as introducer needles for the transpedicular access. Then, through its cannula with a coaxial technique, it is possible to put a biopsy needle and thereafter perform a VTP/KYP with the cement.

1.
PREPARE THE WORKING CHANNEL
Start by creating a stable working channel using the instruments provided in the RENOVA SPINE™ or vertebroplasty kit. Follow the specific instructions for use to ensure safe and accurate access to the vertebral body.
2.
INTRODUCE THE BIOPSY NEEDLE
Insert the VERTEBRAL BIOPSY DEVICE (Option 1 or 2) into the working channel. Ensure precise positioning at the targeted biopsy location, always under fluoroscopic guidance.
3.
PERFORM THE BIOPSY
OPTION 1 – ASPIRATION METHOD: Once the biopsy site is reached with Device Option 1, attach a syringe to the Luer Lock connector and perform an aspiration to collect the tissue sample.
OPTION 2 – ROTATIONAL CUTTING: With Device Option 2, rotate the needle 360° twice to internally cut and isolate the tissue sample. This technique avoids displacement or trauma to surrounding structures.
4.
REMOVE THE SYSTEM
For both options, carefully withdraw the entire biopsy system from the working channel, maintaining the integrity of the sample during removal.
5.
SAMPLE EXTRACTION
OPTION 1: Insert the Extractor from the grip side to push out the sample and place it onto a slide or container for analysis
OPTION 2 – First, extract the internal stylet using cutting wire. Then, insert the finger-protection device and the Extractor from the opposite side of the grip to safely retrieve the sample.
6.
FINAL CHECKS AND SAMPLE HANDLING
Ensure that the sample is properly collected and preserved for histological examination.
It is now possible to continue with kyphoplasty or vertebroplasty operations.
