New nerve block may help you walk sooner after bunion surgery
NCT ID NCT03922412
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two different nerve blocks for pain after hallux valgus (bunion) surgery. One group received a standard sciatic block, while the other received a plantar block combined with a distal peroneal block. The goal was to see which approach allows patients to walk better and recover faster. Sixty adults scheduled for outpatient bunion surgery took part, and their walking ability, pain, and satisfaction were measured for three days after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- nerve block (local anesthetics mepivacaine and ropivacaine with dexamethasone)
- What this could lead to
- If successful, this could show that a plantar block allows better walking ability after bunion surgery compared to a standard sciatic block.
- What could go wrong
- This is a small, single-center study with only 60 participants, so results may not apply to all patients. The study is completed, but findings may not lead to a change in practice without larger trials.
