## Indications for use
A RF Injection Needle is an injection needle, which may be used either for percutaneous nerve blocks with local anesthetic solution or for radiofrequency lesioning. The nerve is localized either by using electrical stimulation through the needle or by injection contrast medium through the needle and using radiography concomitantly. The nerve may then be blocked by injecting local anesthetic or a radiofrequency lesion may be made.
