Non-Facet Degenerate Joint Disease or DJD
First, let’s explain that the spine consists of a column of moveable bones called the vertebrae. The vertebrae connect to one another by means of articulation.
Each vertebrae works as a three-joint system with a large pliable disc in the anterior portion of the bone. There are two facet joints posteriorly or towards the back of the bone.
This triple-design is very sturdy and keeps the bones connected together while also allowing the spine to bend and twist.
The facets are synovial joints which are lined with cartilage. This cartilage is lubricated with synovial fluid and covered by a joint capsule.
A healthy facet joint glides or moves as the spine moves but help to prevent over-twisting.
So a Non-Facet DJD or Not Facet DJD would be any other part of the spine that does not include the articulating facet area.
If your radiology report says your degenerative joint disease is “not facet” than it is saying your disease is simply not related to the facet area of the spine.
