Systematic Review and Meta-analysis of Radiofrequency Ablation for Morton's Neuroma: Outcomes and Predictors of Success.

OBJECTIVE

Morton's neuroma presents a challenge in terms of pain management. This study aimed to evaluate the available evidence on the efficacy and safety of radiofrequency ablation for Morton's neuroma.

DESIGN

The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. Prospective clinical trials, cohort studies, and case series were also included. Data analysis was performed using Review Manager 5.4. Meta-analysis applied fixed- or random-effects models depending on the heterogeneity. Sensitivity analyses were performed to assess the effects of temperature, radiofrequency cycles, and imaging guidance.

RESULTS

Eight studies ( N = 237) were included. Significant pain reduction was observed at the final follow-up (mean difference = 5.74; 95% confidence interval = 5.58, 5.90). At the final follow-up, 47.57% (95% confidence interval = 25.13%-70.00%) experienced complete pain relief, while 16.40% (95% confidence interval = 11.86%-20.94%) reported no benefit at final follow-up. Sensitivity analyses found higher-temperature settings (≥85°C) conferred greater relief on visual analog scale (mean difference = -6.97; 95% confidence interval = -6.75 to -7.18) compared to temperatures <85°C (mean difference = -3.94; 95% confidence interval = -3.68 to -4.19). Fewer radiofrequency cycles (≤3) also demonstrated significantly greater visual analog scale improvement (mean difference = -6.97; 95% confidence interval = -6.75 to -7.18) versus >three cycles (mean difference = -4.79; 95% confidence interval = -3.02 to -6.57). Complications were minimal (2.1%), and most resolved without significant interventions.

CONCLUSIONS

Radiofrequency ablation, particularly at specific temperatures and cycle thresholds, is effective and safe for the management of Morton's neuroma.
