Bracing options after an ankle fracture

Official title: Bracing After Ankle Fracture (BAF): a Randomised Multicenter Non-inferiority Trial Comparing Ankle Stirrups to Walkers on Pain, Function and Social Interaction for Adults After Ankle Fracture - Study Protocol

Run by Odense University Hospital · NCT07163091 · Data updated 2026-11-12

This trial will test whether a less rigid ankle stirrup works as well as a standard walker to reduce pain and improve function three months after an ankle fracture in adults.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with a recent ankle fracture treated surgically or non-surgically who can adhere to follow-up and read Danish are ideal candidates.

Probably not a fit

Patients with open or pathological fractures, those who need prolonged immobilisation or restricted weightbearing, or those unable to adhere to procedures (for example severe neuropathy or major psychiatric disorders) are unlikely to benefit from the less restrictive stirrup.

What this trial studies

This randomized non-inferiority trial compares an ankle stirrup to a standard foot-ankle brace (walker) in adults with surgically or non-surgically treated ankle fractures. The primary outcome is pain and function measured by the Manchester-Oxford Foot Questionnaire (MOXFQ) at three months, with a planned sample of up to 1,400 participants to enable subgroup analyses by age, sex, and treatment type. Secondary outcomes include time to return to work, complication rates, and cost, and participants will be followed for recovery and adverse events. The trial aims to determine whether the less restrictive stirrup offers similar clinical outcomes while improving patient experience and recovery speed.

Why it matters

Potential benefit: If successful, patients could have a less restrictive brace option that may speed recovery, improve comfort, and shorten time off work without increasing complications.

How similar studies have gone: A prior randomized trial (Smeeing et al. 2020) indicated similar functional outcomes and faster return to work with less restrictive devices but was terminated early and underpowered, so evidence remains limited and inconclusive.
