New pain shot could replace catheters after leg amputation

NCT ID NCT05140499

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested two standard pain relief methods after below-knee amputation: a long-lasting numbing injection (liposomal bupivacaine) versus a continuous nerve catheter that delivers numbing medicine. The goal was to see which provides better pain control and reduces the need for opioids. Only 11 people took part before the study was stopped early, so the results are very preliminary.

What this could mean

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

Active substance

Liposomal bupivacaine (Exparel) and bupivacaine hydrochloride

What this could lead to

If this works, it could show that a single injection controls pain as well as a catheter, possibly reducing opioid use and simplifying recovery after amputation.

What could go wrong

This is a very small pilot study (11 participants) that was terminated early, so results are preliminary and may not apply widely. Neither method is new, so the upside is modest.
