Summary

Adult patients who were planned for lumbar facet joint medial branch nerve Radiofrequency ablation under fluoroscopic guidance because of facet joint-originated chronic lower back pain will be included in this study. Pain scores (Numerical Rating Scale and Oswestry Disability Index) will be recorded before and one month after the intervention. The morphology of the transverse processes and the facet joints (sizes and angles) will be evaluated using the computer tomography images that patients have in routine examination process. The possible relationship between the success rate of the procedure and the morphology of the transverse processes will be assessed by statistical analysis.

Conditions

  • Lower Back Pain Chronic

Interventions

PROCEDURE

Lumbar facet joints medial branch nerve radiofrequency ablation

Patients will be positioned prone on the operation table. Intravenous access is opened. Monitorization for vital signs is performed. Light sedation with midazolam is performed. Under fluoroscopic guidance, medial branch nerve of each lumbar facet joint is found by searching the specific response to the stimulations of the radiofrequency needle. When the tip of the radiofrequency needle is close enough to the corresponding medial branch nerve, ablation with 80 degrees Celsius for 90 seconds is performed. Average 6-10 nerves are ablated in each procedure and the average duration of the procedure is 20-60 minutes.

PROCEDURE

Lumbar facet joints medial branch nerve radiofrequency ablation

Patients are positioned prone on the operation table. Intravenous access is opened and monitorization of vital signs is applied. Skin is cleaned by povidone iodine solution. Light sedation is applied by midazolam. Lumbar vertebral region is seen under C-arm fluoroscopic view. Medial branch nerve of the lumbar facet joints is searched by 22 G width, 10-cm length radiofrequency needles. When the needle tip is close enough to the nerve, an 80 Celsius, 90-second radiofrequency ablation is applied. In each procedure, average 5-10 nerves is ablated and the duration of the procedure is 20-60 minutes.
