Is this trial a fit for you?

Likely a good fit

Adults (18+) with intractable postamputation pain due to painful neuromas who are eligible for surgery and can consent.

Probably not a fit

Patients with contraindications to anesthesia or those whose pain persists despite surgical intervention may derive little or no benefit.

What this trial studies

This observational study at Leiden University Medical Center explores surgical approaches for postamputation pain due to neuromas. It focuses on two techniques, fascicular split and targeted muscle reinnervation, to see if they provide pain relief when non-surgical options have failed. Participants are adults with intractable postamputation pain and suitable for anesthesia. Outcomes include pain relief and quality of life following the procedures. The study builds on long-standing experience with neuroma treatment at the Leiden Nerve Center and reports results from real-world clinical practice.

Why it matters

Potential benefit: If successful, participants may experience meaningful reduction in residual and phantom limb pain and improved prosthesis use.

How similar studies have gone: Previous experiences with fascicular split and nerve implantation techniques have reported substantial pain relief in selected patients, supporting potential benefit of these approaches.
