One-Needle Vs Three-Needle Radiofrequency in Low Back Pain Due to Facet Joint Arthritis

The primary outcome is to study the efficacy of the described technique which creates a lesion that we estimate to be 11.0-mm wide and 11.6-mm long along the course of the medial branch adjacent to the SAP ensuring adequate coverage and treatment using VAS score. Responder status was defined as a 30% or greater improvement in VAS pain score from the pre-procedural VAS pain score. Outcomes were summarized by means and standard deviations for continuous outcomes, and frequencies (%) for categorical outcomes.

The primary outcome is to study the efficacy of the described technique by maximizing the lesion size (compared to control group) along the course of the medial branch adjacent to the SAP ensuring adequate coverage and treatment using VAS score.
