Clinical efficacy assessment of cooled radiofrequency ablation of the hip in patients with avascular necrosis.
Aim: This pilot case series examined feasibility of anterior radiofrequency approach under combined ultrasound and fluoroscopy guidance to control pain from avascular necrosis of the hip. Patients & methods: Data on 11 consecutive patients were collected on longevity of cooled radiofrequency ablation (CRFA), pain relief and opioid use. Results: The average age was 56 (28-66), BMI 29.5 (16.5-34), in four women and three men. Their average opioid use was 92 mg MS04 equivalents (median 35 mg). The pain score decreased to 3.3 after the CRFA. Five patients claimed more than 50% of pain relief. The average time interval of greater than 50% of pain relief from the CRFA was 70-250 days. Conclusion: CRFA may be an effective treatment of chronic pain from avascular necrosis.
