Hip chronic pain: ultrasound guided ablation of anterior articular branches plus posterior neurolysis of the nerve to the quadratus femoris versus the alone anterior approach-a retrospective observational study.
Journal of Ultrasound 2024 March 22
INTRODUCTION: Chronic hip pain is a common painful condition in the elderly population. A mini invasive technique that is increasingly being considered for management of CHP is the percutaneous denervation of hip articular branches via radiofrequency ablation. We described a new ultrasound-guided technique based on the combination of 90° ultrasound-guided anterior radiofrequency ablation of the articular branches of femoral nerve, accessory obturator nerve and obturator nerve for anterior hip, combined with 90° ultrasound-guided ablation of the articular branches of the nerve of the quadratus femoris for posterior pericapsular neurolysis of the hip.
MATERIAL E METHODS: We retrospectively analyzed the medical records of patients from September 2022 to September 2023 treated for chronic hip pain in the ambulatory of Pain Management, identifying 22 patients who underwent ultrasound guided radiofrequency denervation of anterior hip articular branches alone (Group B); and 22 patients in which was also applied a radiofrequency denervation of the posterior articular branches, in addition to the anterior denervation (Group A). We analysed the pain intensity of both groups measured with numeric rating scale.
RESULT: The combined anterior plus posterior approach ensured that the results obtained were maintained 6 months after the procedure (T3) with excellent pain control and an average NRS of 1455 for group A. While for the group B, with the anterior approach alone, the NRS at six months showed an upward trend with an average NRS of 3818. The dual approach is more effective in pain relief at 6 months with a statistically significant difference in NRS values (p < 0.001).
CONCLUSION: This retrospective observational study highlighted the greater impact of the double approach (anterior plus posterior) in the denervation of the hip joint, compared to anterior neurolysis alone.
