Ultrasound-Guided Cryoneuroablation as a Treatment for Post-Amputation Neuroma in a Pediatric Patient

Abstract

Introduction: Post-amputation pain is a frequent and limiting complication, especially in pediatric patients. Stump neuromas represent a common cause of refractory neuropathic pain, with few effective therapeutic options available.
Objective: To describe the use of ultrasound-guided cryoneuroablation as a minimally invasive alternative for the treatment of painful post-amputation neuroma in a pediatric patient.

Methods: A 10-year-old girl with left transtibial amputation due to meningococcal sepsis and severe neuropathic pain (VAS 8/10) secondary to a tibial nerve neuroma, refractory to conventional treatment. Ultrasound-guided cryoneuroablation of the tibial nerve was performed under general anesthesia.
Results: The procedure was completed without complications, achieving pain reduction to VAS 1/10 and full functional recovery within two weeks.
Conclusions: Ultrasound-guided cryoneuroablation is a safe, effective, and minimally invasive technique for the management of painful post-amputation neuroma in the pediatric population, providing novel evidence in this understudied group.
