What this trial studies

This single-center Phase 2 interventional trial at Massachusetts General Hospital applies the Tulavi Allay nerve cap to transected digital nerves at the time of traumatic finger or toe amputation. Participants are English-speaking adults undergoing primary traumatic digital amputation who meet device safety criteria and are followed for patient-reported pain, neuroma incidence, and emotional and social impact measures. The protocol excludes revision or non-traumatic amputations, those under 22 years, pregnant or breastfeeding individuals, and people with known allergies to device components. Study outcomes compare post-amputation pain and functional impact with historical rates and previously reported surgical techniques to determine if the nerve cap reduces symptomatic neuroma and need for later surgery.

Who should consider this trial

Good fit: Adults aged 22 or older who are English-speaking and undergoing a primary traumatic single or multiple digital amputation at Massachusetts General Hospital, without allergy to the device materials, are ideal candidates.

Not a fit: People having revision or non-traumatic amputations, those under 22, pregnant or breastfeeding individuals, or patients with known PEG or specified dye allergies are excluded and would not benefit from this trial.

Why it matters

Potential benefit: If successful, the nerve cap could lower the chance of painful neuroma formation after digital amputation and reduce the need for follow-up surgeries, improving daily function and comfort.

How similar studies have performed: Earlier descriptive reports and one small prospective trial comparing conventional surgical techniques exist, but the use of a synthetic nerve cap like Tulavi Allay is relatively novel with limited clinical outcome data.
