Brief summary (from the registry)
Patients with combat-related amputations frequently experience chronic neuroma pain that may interfere with rehabilitation, prosthesis use, mobility, sleep, and quality of life. Ultrasound-guided botulinum toxin type A injection has emerged as a potential treatment option for persistent neuroma pain; however, the optimal injection technique remains unclear. This prospective multicenter study aims to compare two ultrasound-guided botulinum toxin injection techniques for chronic neuroma pain after combat-related amputation: intraneuroma injection and perineuroma injection. Participants with ultrasound-confirmed painful neuromas will undergo one of the two injection approaches based on the treating physician's clinical decision and local practice. Pain intensity, neuropathic pain characteristics, phantom limb pain, prosthesis tolerance, functional outcomes, and adverse events will be evaluated during follow-up. The goal of the study is to evaluate the feasibility, safety, and potential clinical effectiveness of intraneuroma and perineuroma botulinum toxin type A injection techniques in patients with chronic neuroma pain following combat-related amputation.
