Lumbar facet joint blocks (FJB) are performed for diagnostic and/or therapeutic purposes, and are generally carried out under fluoroscopy-guidance. Precise intra-articular injection is desirable for diagnostic specificity, and therapeutic efficacy. Our purpose was to assess the rate of procedural success profile of FJB under CT-guidance and to estimate patient periprocedural radiation doses.

Methods & Materials

We retrospectively reviewed a series of clinically indicated FJB procedures in 37 consecutive patients (13 men, 24 women; mean age 60±12 years; age range 37-82 years) for a total of 47 procedures, and a total of 84 targeted facet joints. All procedures were performed under local anesthesia using a 22G beveled spinal needle, either 3.5â
