Proximal Nerve Cryoablation Versus Perineuroma Cryoablation for Chronic Neuroma Pain After Combat-Related Amputation

Sponsor: Ukrainian Society of Regional Anesthesia and Pain Therapy

Summary

atients with combat-related amputations frequently develop chronic neuroma pain that interferes with rehabilitation, prosthesis use, mobility, sleep, and quality of life. Cryoablation is a minimally invasive treatment that produces controlled nerve injury using extreme cold. Although the freezing effect is localized around the cryoprobe, axonal interruption followed by distal Wallerian degeneration may extend functional denervation distal to the ablation site. This study aims to compare two ultrasound-guided cryoablation strategies for chronic neuroma pain after combat-related amputation: cryoablation performed directly near the neuroma and cryoablation performed proximal to the neuroma along the affected nerve. The study will evaluate whether proximal nerve cryoablation produces greater or longer-lasting analgesic effects compared with perineuroma cryoablation.
