Official title: Conservative Treatment With Relative Motion Flexion (RMF) Orthosis for Boutonniere Injuries
Run by Lund University Hospital · NCT07921927 · Data updated 2026-11-12
This study tests a Relative Motion Flexion orthosis to treat recent boutonnière injuries of the finger and see if it helps restore finger function without surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults with acute or subacute closed central slip injuries of the finger (zone 3) and a positive pencil test, without open wounds or other exclusion criteria.
✕Probably not a fit
Patients with chronic injuries beyond one year, open injuries, infection, significant joint contracture, or multiple concurrent hand injuries may not benefit from this approach.

What this trial studies
This is a prospective longitudinal pilot cohort study evaluating the Relative Motion Flexion (RMF) orthosis for acute and subacute central slip injuries of the finger. Eligible participants have closed injuries to the extensor tendon zone 3 and a positive pencil test. The study measures functional outcomes over time as the RMF device is used during rehabilitation, with follow-up designed to assess safety and feasibility in a real-world setting. It builds on limited prior evidence by systematically observing outcomes in a defined clinical pathway at a single hand surgery rehabilitation unit. No randomization or control arm is described in the current protocol, and results will inform future larger studies.
Why it matters
Potential benefit: If successful, patients may experience improved finger motion and function with a non-surgical treatment approach.
How similar studies have gone: Previous reports of RMF and similar conservative approaches are limited to small case series; this pilot aims to provide more systematic prospective data.
