Can you tell me what is bilateral facet joint effusions?

Arthritis: Joints in the spine are similar to joints in the rest of the body. When they degenerate due to arthritis they become fluid filled. That fluid is referred to an effusion. An effusion is basically indicative of degeneration of that joint. It can lead to pain, and in severe cases, instability of that vertebral level.

Water in the joint: When joints get worn or degenerative, they can produce more joint fluid than usual and it is called an effusion. It is the joint's attempt to heal. Bilateral means on both sides as there are two facet joints per level. This can also be a sign of inflammation or arthritis of the joints that could lead to pain and/or instability.

Facet joint effusion: There are 3 moving parts of each level of the spine--2 facet joints, and disc. The joints protect the spine and spinal cord from abnormal motion or translation. In everybody, as we age, the joints degenerate and lead to "changes" seen on studies. An effusion is a sign that there is abnormal translation occurring, most commonly resulting in a spondylolisthesis.

Spine Joints: Facet joints are places on the spinal bones where two bones actually meet and articulate. Many times arthritis or inflammation can arise here and cause pain. Sometimes this inflammation results in extra fluid in the joint that aggravates the joint, that is the effusion. Suggest seeing a spine specialist to get help with either steroid injections or PRP to help strengthen ligaments.
