Comparative Evaluation of Intraneuroma and Perineuroma Botulinum Toxin Type A Injection Techniques for Chronic Neuroma Pain After Combat-Related Amputation

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.

Evacuation Time and Tourniquet Use as Risk Factors for PTSD in Combat-Related Amputation

This study aims to evaluate the relationship between evacuation time, tourniquet use, and the development of post-traumatic stress disorder (PTSD) in patients with combat-related amputations. In the context of modern warfare, prolonged evacuation times and extended tourniquet application may contribute not only to physical injury but also to psychological trauma. The study will prospectively follow patients over 18 months to identify key predictors of PTSD and to assess their interaction.
