Ultrasound-Guided Cryoablation of a Traumatic Hip Disarticulation Neuroma.

OBJECTIVE Traumatic amputation at the pelvic level is a rare procedure with few studies addressing long-term complications. Painful neuroma formation may form at the site of nerve transection and cause significant impairments in daily living. Ultrasound-guided cryoablation therapy has grown in popularity and should be considered in patients with painful neuromas. This is a case report of complete pain relief in a patient with rare traumatic hip disarticulation with neuroma formation, treated with ultrasound-guided cryoablation. The patient gave consent for publication. DESIGN Single case report. SETTING Mount Sinai Medical Center. PATIENT A 57-year-old man with traumatic hip disarticulation over 30 years ago with a 10-year history of severe residual limb pain from neuroma formation. INTERVENTIONS Ultrasound-guided cryoablative injection therapy. OUTCOME MEASURES Pain reduction. RESULTS Ultrasound-guided cryoablation of a traumatic hip disarticulation neuroma resulting in complete pain relief and improved functionality and independence. CONCLUSIONS This case illustrates a rare incidence of painful neuroma formation in a patient with traumatic hip disarticulation. Cryoablation with ultrasound guidance resulted in resolution of all pain. We report, to the best of our knowledge, the first occasion of an ultrasound-guided cryoablation resulting in complete pain relief in a traumatic hip disarticulation neuroma.
