Study summary

In a randomised prospective comparative Trial the investigators aim to compare the conservative Treatment of acromioclavicular dislocations (Rockwood III) with a conventional sling versus a Acromion 2.0 brace, which exerts a direct Reposition force on the Joint.

The sling/brace will be worn for 6 weeks and the patients will be regularly checked clinically and radiologically.The investigators are interested in differences of shoulder function, Patient satisfaction as well as cosmetic and radiological results.

Inclusion criteria

  • First acute acromioclavicular dislocation Rockwood Type III

Exclusion criteria

Exclusion Criteria:

  • Previous injury to acromioclavicular Joint
  • Previous surgery of acromioclavicular Joint
  • Known or allergy to fabric of product
  • Pregnancy
  • Known or suspected non-compliance, drug or alcohol abuse
  • Inability to follow the procedures of the study, e.g. due to language problems, psychological disorders, dementia, etc. of the participant
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2017 to primary completion in Dec 2020, 39 months.

Of 24 interventional studies with no phase under Joint Dislocations, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 68. This study's 39 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 13, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
