摘要

Background: Pain generated from lumbar facet joint affection is considered a common cause of low back pain. Image-guided facet joint infiltration is performed to reduce pain severity and to confirm its source. Aim: The objective of this study is to assess the accessibility, and accuracy and to evaluate the functional outcome of the CT-guided lumbar facet joint infiltration in management of low back pain. Subjects and Methods: This retrospective study included thirty four patients. All patients were diagnosed with low back pain due to lumbar facet syndrome. Adequate conservative therapy failed to improve the patient’s symptoms. Totally, 81 lumbar facet joints were treated by CT-guided intra-articular infiltration. Mean time of hospital stay was 6 - 8 hours. In the procedure technique, measures were applied to reduce the patients’ radiation exposure. The response to treatment was evaluated by the visual analogue scale (VAS) before procedure and at follow-up visits. Results: Among 34 adult patients included in this study, 26 were males and 8 were females. The mean age was 49.5 ± 8.5 years. Mean Duration of low back pain on admission was 8.2 ± 3.5 months. Bilateral CT-guided intra-articular infiltration was performed in 23 patients (67.5%). Assessing the response after facet joint infiltration, 82.4% of the patients showed immediate pain improvement after the procedure;85.3% of the patients reported pain relief after 1 month and 67.6% at 12 month follow up. There was a statistically significant relief of pain after the intervention at 12 month follow up (p Conclusion: Lumbar Facet joint infiltration guided with CT scanning seems to be a reliable and safe procedure for low back pain management. Beside immediate and long term pain relief achieved using this minimally invasive technique;CT guidance provides an accessible and accurate route for the needle with low radiation dose exposure.
