The authors did not perform synovial cyst rupture as part of their intervention.Percutaneous rupture of lumbar facet joint synovial cysts has been described in a number of retrospective studies.2–8 Technical success can be achieved in almost all patients using proper image guidance and appropriate technique. Traditionally, fluoroscopy has been used for needle placement as it is widely available, inexpensive, and provides real time procedural guidance. CT imaging provides significant advantages over fluoroscopy for accessing degenerated facet joints that develop synovial cysts as cross-sectional imaging can reveal an approach to osteophytic … ER -
