What this trial studies

This observational study aims to evaluate the effectiveness of Regenerative Peripheral Nerve Interfaces (RPNI) surgery in alleviating neuroma pain in patients who have undergone digit or hand amputations. Participants will be assessed using validated patient-reported outcomes and will undergo a thorough evaluation of their pain management and functional capabilities before and after the surgery. The study will compare the outcomes of RPNI surgery with standard care practices to determine the potential benefits of this innovative approach.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a history of unilateral digit or hand amputation and discrete neuroma pain.

Not a fit: Patients who have previously undergone surgical treatment for symptomatic neuromas or have other major injuries causing chronic pain may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce pain and improve function for patients suffering from neuromas after amputation.

How similar studies have performed: While the use of RPNI is a novel approach, similar studies have shown promise in addressing neuroma pain, indicating potential for success.
