Comparison of Efficacy of Lateral Branch Radiofrequency Denervation and Intraarticular Depot Methylprednisolone Injection for Sacroiliac Joint Pain

METHODS: This prospective study enrolled 30 patients with clinically proven sacroiliac joint discomfort and who experienced greater than 50% pain alleviation following intra-articular diagnostic block injection. Patients were randomly assigned to one of two groups: group A received intra-articular methylprednisolone injections, while group B had standard radiofrequency denervation of the L4 L5 dorsal rami and S1-3 lateral branches. Numeric Rating Scale (NRS) before the procedure and at 2 weeks, one month and three months after the procedure, Oswestry Disability Index (ODI) before the procedure and at one and three months after the procedure and Global Perceived Effect (GPE) after three months, were used as outcome parameters to compare between both groups.
