Surgical Techniques for Phantom and Residual Limb Pain After Amputation

This study is looking at two surgical techniques, Targeted Muscle Reinnervation (TMR) and Regenerative Peripheral Nerve Interfaces (RPNI), to help cancer patients who have had an amputation and are experiencing chronic residual limb pain or phantom limb pain. These techniques involve connecting cut nerves to muscles to help them heal. Researchers want to see if using TMR, RPNI, or a combination of both is most effective in reducing pain. They will also look at how much pain medication you use and if you use a prosthetic limb. This study is for adults aged 18 and older who are having an amputation for cancer reasons and have suitable nerves for these procedures. The study aims to understand the safety and effectiveness of these treatments.

Study design
This interventional study plans to enroll 45 participants. You would be randomly assigned to one of three groups: TMR alone, RPNI alone, or TMR combined with RPNI.
What's involved
You would undergo one of the surgical procedures and then have follow-up appointments at 3, 6, and 12 months after the surgery.
Compensation
Not stated in the trial record.
Follow-up
You would be followed for an average of 1 year to monitor safety and adverse events.

Eligibility criteria

Inclusion

Patients greater than or equal to 18 years of age who are receiving an amputation for oncologic reasons
Patients with available mixed major nerves and donor motor nerves in the amputation stump or reconstructive tissue
Patients able to complete informed consent

Exclusion

Patients under 18 years of age
Patients unable to give consent
Patients receiving an amputation for non-oncologic purposes
Patients with amputations performed for immediate palliation (life expectancy less than 3 months), as this technique takes a minimum of 3-6 months for effect
Patients with multiple limb amputations
Patients receiving nerve management in a delayed fashion (patients who have previously received an amputation and present with neuroma)
