New screw technique aims to mend stubborn ankle breaks
NCT ID NCT07539922
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a surgical procedure using two compression screws to fix ankle fractures that have not healed after at least 6 months. Ten adults aged 18 to 65 with a specific type of non-union will be treated and followed for 12 weeks to see if the bone heals and pain improves. The goal is to find a better way to treat these difficult fractures.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Double compression screw fixation procedure
- What this could lead to
- If successful, this could provide a reliable surgical option to heal non-union ankle fractures, restoring function and reducing pain.
- What could go wrong
- This is a very small, early study with only 10 participants, so results may not apply to everyone. Surgery carries risks like infection or nerve damage.
