Explain kenalog (triamcinolone) facet joint injections?

Why?: Although i used to give them, studies by deyo, et al, and others more recently, have shown little benefit over a systemic steroid injection. The injection is delivered to the facet joint, the true synovial joints of the spine. Afcet joints problems are likely if you have pain with backward extension of your spine.

Given for diagnosis: Facet blocks are used for diagnostic purposes and can be also combined with a steroid such as kenalog (triamcinolone) for additional short term relief if this is the source of the back pain. The facet joints are true joints located in the spine, 2 at each level that are load bearing and allow for certain motions and can be injured or develop arthritis.
