Rerouting nerves during amputation may stop phantom pain before it starts

NCT ID NCT05408520

First seen Jul 24, 2026 ยท Last updated Jul 24, 2026

Summary

This trial tests whether a surgical technique called targeted muscle reinnervation (TMR) can reduce nerve pain and phantom limb pain after a leg amputation. TMR reroutes severed nerves to nearby muscle nerves to encourage organized regrowth. Adults scheduled for a below- or above-knee amputation will be randomly assigned to receive either standard amputation or amputation plus TMR, and their pain levels will be compared over time.

What this could mean

Our plain-language read of the trial. This is informational only โ€” not medical advice or a prediction.

Active substance
a surgical procedure called targeted muscle reinnervation (TMR) that reroutes severed nerves to nearby muscle nerves to encourage organized regrowth
What this could lead to
If it works, this could become a standard surgical technique to prevent chronic nerve pain and phantom limb pain after leg amputation.
What could go wrong
This is a single-center trial with a small planned enrollment, so results may not apply broadly. The procedure adds surgical complexity and carries typical surgical risks like infection or bleeding.
