Stump Pain

Persistent residual limb pain is common after traumatic amputation and significantly impairs rehabilitation and prosthetic use. Postoperative stump infection may contribute to peripheral nerve sensitization, scar fibrosis, and long-term pain persistence. This prospective cohort study aims to determine whether early post-amputation stump infection independently predicts persistent clinically significant residual limb pain at 3 and 6 months after surgery.

Patients with combat-related amputations frequently experience chronic neuroma pain that may interfere with rehabilitation, prosthesis use, mobility, sleep, and quality of life. Current treatment approaches often provide only temporary pain relief. Platelet-rich plasma (PRP) has emerged as a potential regenerative treatment option because of its possible effects on tissue healing, neuroinflammation, and peripheral nerve irritation. However, its role in the treatment of chronic neuroma pain after amputation remains unclear. This prospective multicenter controlled study aims to compare ultrasound-guided PRP injection around the neuroma with ultrasound-guided local anesthetic injection in patients with chronic neuroma pain after combat-related amputation. Participants will undergo one of the two injection treatments and will be followed over time to evaluate changes in pain intensity, neuropathic pain symptoms, phantom limb pain, prosthesis tolerance, and functional outcomes. The goal of the study is to evaluate the safety, feasibility, and potential clinical effectiveness of PRP injection for chronic neuroma pain following combat-related amputation.
