Spinal stenosis

This is the narrowing of the spinal canal and nerve root canal which can lead to lower back pain and leg pain.

Degenerative disc

Spondylolisthesis

The weakness or fracture between the upper facets and the lower facets of the vertebra is known as spondylolisthesis. This may cause the vertebra to slip forward and compress the nerve roots leading to pain.

Sciatica

Your doctor uses the fluoroscope to see through your skin in order to know if the needle is in the right position. A contrast dye is then injected into the area so that your doctor can see the position of the needle more clearly.

When the needle is placed in the right position, corticosteroid medication is injected into the area to reduce the inflammation and an anesthetic agent such as lidocaine or bupivacaine is also applied to relieve the pain.

The corticosteroids and anesthetic agent injected will spread over several spinal segments and cover both sides of the spinal canal.

After the medication has been injected, your doctor will then slowly remove the needle and clean up the skin around the injection site.

It usually takes between 20-40 minutes for the procedure to be completed.

After the procedure

Results of the procedure
