Summary

This study planned to see if injecting a patient's own fat into the fingertip could reduce pain and discomfort after a fingertip amputation. It was designed for adults with persistent nerve pain lasting 6 to 24 months after injury. However, the study was withdrawn before enrolling any participants, so no conclusions can be drawn.

What this could mean

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

Active substance
autologous fat graft (lipofilling)
What this could lead to
If it worked, this could offer a simple surgical option to reduce chronic pain and sensitivity after fingertip amputation.
What could go wrong
The study was withdrawn before any participants were enrolled, so no results are available. It is unknown if the procedure is effective or safe for this use.
