The use of intraoperative X-rays is necessary in a large number of procedures. In lumbar spine disorders, they are needed to identify the vertebral segment that should be operated and to focus the surgical incision on this segment. X-rays are used in the percutaneous treatment of chronic pain such as facet joint infiltration, epidural and foraminal infiltrations and radiofrequency procedures. In addition X-rays are essential for the confirmation of the correct position of some spinal implants (transpedicular screws, disc prostheses, etc …). In DBS surgeries X-rays are useful to confirm the correct depth of the implanted electrodes.
