Can a brace replace the cast for certain ankle fractures?
NCT ID NCT05412693
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This trial compares a functional brace to a traditional cast for treating a specific type of partially unstable ankle fracture (Weber B/SER4a). Adults aged 18 to 80 with these fractures are randomly assigned to wear either a brace or a cast for six weeks. The goal is to see if the brace is just as effective as the cast at reducing pain and improving foot and ankle function over two years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a functional orthosis (brace) compared with a traditional cast
- What this could lead to
- If the brace works as well as a cast, people with this type of ankle fracture could have a more comfortable and convenient treatment option.
- What could go wrong
- This is a relatively small trial, and the brace might not provide enough support for proper healing, leading to worse outcomes than a cast.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients: * With isolated Weber type B fractures that are deemed stable on weightbearing radiographs (MCS injured ankle - MCS uninjured ankle \< 1 mm). * With concomitant gravity stress test evaluated as unstable (MCS injured ankle - MCS uninjured ankle \< 1 mm) * Presenting to one of the participating hospitals, and that are available for stability evaluation within 14 days after injury. * 18-80 years of age * With pre-injury walking ability without aids. Exclusion Criteria: * Patients: * with fracture of the medial malleolus, pre-hospital closed fracture reduction, open fracture, fracture resulting from high-energy trauma or multi-trauma or pathologic fracture. * with fracture of the posterior malleolus involving 25% or more of the joint surface or with a step of the intraarticular surface. (non-displaced fractures smaller than 25% can be included) * with neuropathies and generalized joint disease such as Rheumatoid Arthritis. * that are assumed not compliant (drug use, cognitive- and/or psychiatric disorders). * with previous history of ipsilateral ankle fracture. * with previous history of ipsilateral major ankle-/foot surgery. * who live outside one of the participating hospitals catchment areas (not available for follow-up).
