What are these Lumbar Facet Joints?

Simply put, Lumbar Facet Joints are the small joints in our lower back, behind the vertebrae (spine). These are also called (Zygapophysial joints).

Think about your knee. Just as the knee joint allows us to bend and extend our leg, these facet joints allow us to bend forward, rotate to the sides, and keep our spine straight. There is a lubricating fluid inside these joints. This helps these joints move smoothly without rubbing against each other.

However, when these joints wear out, that is, when arthritis conditions such as Facet Arthropathy'' occur, unbearable back pain can occur.

So what is this Lumbar Facet Joint Injection?

This is also called a Lumbar Facet Joint Block. This involves injecting a local anesthetic agent into or near the painful spinal joint. Sometimes a steroid is also added to this to reduce pain and swelling. Depending on your condition and the number of joints that are affected, you may need to have one or more injections.

This is a standard treatment method commonly used by doctors who treat back pain. It is particularly effective for pain caused by degenerative disc disease and some mechanical causes of lower back pain (mechanical lower back pain).

This treatment is performed by doctors or specially trained nursing staff who have received specialist training in pain management , spinal treatment, or physical therapy and rehabilitation.
