Facet joints are paired joints in the neck and back region and serve to connect one vertebrae to the next, hence forming a joint. Facet joint injections are sometimes known as facet blocks, as they are essentially administered to block pain that is generated from the facet joints as diagnosed clinically and by MRI. Medial branch blocks are another less invasive approach designed as both diagnostic and therapeutic for facet mediated pain and are often preferred, especially for extremely arthritic, narrow joints. A local numbing agent and, sometimes, a tiny dose of a steroid medication, will be given to both diagnose and offer pain relief and improve function. These injections can last from hours to months depending on the patient and severity of the arthritis in the facet joints. If they do not provide considerable relief for a few months, then your physician will likely suggest a procedure called Radiofrequency Ablation, which is another pain relief procedure for facet joint mediated pain that can last on average from 6-12 months. Many patients feel immediate relief after the numbing agent alone, without the steroid, but some may need the additional steroid relief. Keeping a pain diary is helpful to aid the doctor in assessing the injection results and planning treatment going forward and Dr. Cardamone will provide one and request that you fill this out for the first few hours following your procedure.
