Selective Nerve Block

Las Vegas Spine and Pain Clinic

Selective Nerve Block 

If a patient experiences pain in an arm or leg that seems to follow a single nerve, the pain management doctors at Las Vegas Spine and Pain Center may recommend a selective nerve block, placed at the area where the nerve exits the spinal column. Depending on the location and type of pain, a selective nerve block may be performed on any area of the spine; cervical (neck), thoracic (mid-back), and lumbar (lower back). However, all blocks serve the same purpose of reducing inflammation and numbing the pain transmitted by the nerve.

A nerve block is an injection consisting of a local anesthetic and a steroid that will be injected under x-ray guidance at the state-of-the-art procedure center at Las Vegas Spine and Pain Center. Injections in the cervical spine have resulted in 46% of patients reporting significant improvement in pain and functional outcome at 6 months. Injections in the lumbar spine resulted in 46% of patients reporting significant improvement in pain and functional outcome at 1 year. Some patients maybe only experience short-term relief for a few weeks. These types of nerve blocks are usually used higher in patients who participate in physical therapy and strengthening exercises.

The procedure goes as follows: 

  • First, an intravenous line will be placed to help sedate and calm you for the procedure. 
  • Then we will place several monitors on you to check your heart, blood pressure, and pulse during the procedure.
  • Then you will lie on your stomach and the site of the injection is numbed
  • Then our doctor will use x-ray guidance and contrast dye to ensure that the needle is in the correct placement. 
  • A local anesthetic and steroid are then injected into the joint, and the needle is removed. 

The block may be diagnostic in nature to assist a surgeon in determining where treatment will be most effective, and a block can be used as a treatment for pain relief. If the patient experiences pain relief following the nerve block, a series of injections may be recommended for long-term pain relief. There are few side effects with selective nerve blocks with pain at injection site being the most common, and infection, bleeding, and nerve damage the least likely.
